Step-by-step explanation:

no explation

Without more information, we cannot give a specific numerical answer for the total interest on a 20-year loan. As a rule, total interest paid will be less on a shorter loan, despite higher monthly payments.

The question is asking how much total interest would Misty pay on a 20-year loan, given she knows the total interest paid on a 25-year loan to be $57,810. We're not given enough information to provide a specific numerical answer for this - the loan interest for a 20-year loan and a 25-year loan involve different payment schedules and amounts - so we can't directly compare or convert the total interest paid.

However, generally speaking, the total interest paid over a shorter loan term (i.e. 20 years) is expected to be less than that of a longer term (i.e. 25 years), assuming all else (loan amount, interest rate) remains equal - this is because the principal balance is being paid down more rapidly, leaving less time for interest to accrue. The trade-off is that monthly payments would be higher on the shorter term loan.

Answer:

11.6 cm²

Step-by-step explanation:

The area (A) of the shaded region is

A = area of sector - area of triangle

area of sector = area of circle × fraction of circle

                       = π × 9.28² ×[tex]\frac{68.9}{360}[/tex] ≈ 51.78 cm²

area of triangle = [tex]\frac{1}{2}[/tex] × 9.28 × 9.28 × sin68.9°

                         = 0.5 × 9.28² × sin68.9 ≈ 40.17 cm²

Area of shaded region = 51.78 - 40.17 ≈ 11.6 cm²

Answer:

y = -2x + 5.

Step-by-step explanation:

The general form is y = mx + b where m = the slope and b = the y-intercept.

So here m = -2 and b = 5 so our equation is:

y = -2x + 5.

ANSWER

The solution is (2,1)

EXPLANATION

The given equations are:

2x+4y=8...(1)

3x-5y=1...(2)

We make x the subject in the first equation to get:

2x=8-4y

This means that,

x=4-2y...(3)

Put equation (3) into equation (2)

3(4-2y)-5y=1

Expand:

12-6y-5y=1

-6y-5y=1-12

-11y=-11

y=1

Put y=1 into equation (3).

x=4-2(1)=2

The solution is (2,1)

Answer:

The right answer is 3a - 11 ≤ 7 ⇒ 4th answer

Step-by-step explanation:

* Lets study the problem

- From the figure

# The blue line started from 6 and the point is bold that means

   the inequality sign is ≤ or ≥

# The blue line started from 6 and moved to the negative numbers

   that means the inequality is less than or equal

∴ a ≤ 6

* Now lets look to the answers

- There is only one answer has the sign ≤ , the last answer

* Now lets solve it to be sure

∵ 3a - 11 ≤ 7 ⇒ add 11 to the both sides

∴ 3a ≤ 18 ⇒ divide the both sides by 3

∴ a ≤ 6

* The right answer is 3a - 11 ≤ 7

Answer:

x^2 + y^2 + 6x - 8y + 21= 0.

Step-by-step explanation:

The center of this circle is (-3, 4) and the radius id 2.

So in Standard form, the equation is:

(x + 3)^2 + ( y - 4)^2 = 2^2

Converting to General form we have:

x^2 + 6x + 9  + y^2 - 8y + 16 = 4

x^2 + y^2 + 6x - 8y + 9 + 16 - 4 = 0

x^2 + y^2 + 6x - 8y + 21= 0.

Answer:

sandals costed $32.55

Step-by-step explanation:

Final answer:

To find the cost of the sandals, subtract the cost of the T-shirt from the total cost. The equation 8.95 + c = 41.50 leads to c = 32.55, meaning the sandals cost $32.55.

Explanation:

The question asks us to find the cost of sandals that Tina bought, given the total cost of a T-shirt and the sandals combined, and the cost of the T-shirt alone. To solve for the cost c of the sandals, we start with the equation 8.95 + c = 41.50. We then isolate c by subtracting 8.95 from both sides of the equation:

c = 41.50 - 8.95

c = 32.55

Therefore, the cost of the sandals was $32.55.

Step-by-step explanation:

The given logarithmic equation is:

[tex]\log_7(x+1)+\log_7x=\log_712[/tex]

Recall and apply product rule of logarithms.

[tex]\log_aM+\log_aN=\log_aMN[/tex]

We apply this property to the left side of the equation to get;

[tex]\log_7x(x+1)=\log_712[/tex]

We take the antilogarithm of both sides to get:

[tex]x(x+1)=12[/tex]

We expand to obtain:

[tex]x^2+x=12[/tex]

We rewrite in the standard quadratic form:

[tex]x^2+x-12=0[/tex]

We factor to obtain:

[tex](x-3)(x+4)=0[/tex]

Either [tex](x-3)=0[/tex] or [tex](x+4)=0[/tex]

Either [tex]x=3[/tex] or [tex]x=-4[/tex]

But the domain is[tex]x\:>\:0[/tex].

[tex]a=1.46[/tex]

Step-by-step explanation:

The triangle of the figure is a straight triangle.

We know the length of the hypotenuse, h = 2, and we know the angle A = 43°. We need to find the length a. Side a is the side adjacent to the 43° angle

By definition we know that

[tex]cosx = \frac{adjacent}{hypotenuse}[/tex]

Then

adjacent = a

hypotenuse  =2

x =43°

[tex]cos(43\°) = \frac{a}{2}[/tex]

[tex]a= 2cos(43\°)[/tex]

[tex]a= 1.46[/tex]

a) The amount after 2 years with continuous compounding is approximately $6539.48.

b) It will take approximately 2.32 years for the amount to reach $8000 with continuous compounding.

a) To calculate the amount after 2 years with continuous compounding, you can use the formula:

[tex]A = P \times e^{rt}[/tex]

Where:

A = the amount after time 't'

P = the principal amount (initial investment)

e = Euler's number (approximately 2.71828)

r = the interest rate (as a decimal)

t = the time in years

Given that P = $5800, r = 6% (0.06 as a decimal), and t = 2 years, we can now calculate the amount (A):

[tex]A = 5800 \times e^{0.06 \times 2}[/tex]

[tex]A=5800 \times e^{0.12}[/tex]

[tex]A=5800 \times 1.1275[/tex]

A=6539.48

Hence,  the amount after 2 years is approximately $6539.48.

b) To find how long it takes for the amount to be $8000, we need to solve for 't' in the formula:

[tex]A = P \times e^{rt}[/tex]

Given that A = $8000 and P = $5800, we can rearrange the formula:

[tex]e^{rt}=\frac{A}{P}[/tex]

[tex]e^{0.06t}=\frac{8000}{5800}[/tex]

Take logarithms on both sides:

[tex]0.006t=log(\frac{8000}{5800})[/tex]

[tex]0.006t=0.139[/tex]

t=0.139/0.06

t=2.327

Hence, it takes 2.32 years for the amount to be $8000.

After 2 years, the investment grows to approximately $6498.78. It will take around 5.37 years for the investment to grow to $8000.

We can use the formula for continuously compounded interest, which is A = Pe^(rt), where P is the principal amount ($5800), r is the interest rate (6% or 0.06), t is the time, and e is the mathematical constant approximated as 2.71828.

a) To find the amount after 2 years, sub in $5800 for P, 0.06 for r, and 2 for t to get: A = $5800 * e^(0.06*2). Evaluating this gives approximately $6498.78.

b) To find out when the amount will be $8000, we set A to $8000 and solve for t, getting: t = ln($8000 / $5800) / 0.06. Evaluating this gives approximately 5.37 years.

Answer:

True

Step-by-step explanation:

The area of a regular polygon is found by multiplying 1/2 times the apothem times the perimeter.  The area for a single triangle is 1/2 times the height (which is the same as the apothem of a regular polygon) times the base (which is one of the sides of the regular polygon which you are multiplying by  to find the perimeter of the polygon).

Answer:

The given statement is true.

Step-by-step explanation:

The area of a regular heptagon can be found by breaking the heptagon into seven congruent triangles and then taking the sum of their areas.

This is true.

Breaking down in 7 triangles and adding separately the areas of these triangles, will give the complete area of the heptagon. We can also find the area of one triangle and multiply that by 7 to get the same result.

Answer:

Your salary will be $62,500.

Step-by-step explanation:

This is an arithmetic sequence with first term $45,000 and common difference $2,500.

The appropriate formula is a(n) = a(1) + (n-1)d, where a(1) is the first term, n is a counter and d is the common difference.

In this particular case, a(8) = $45,000 + (8-1)($2,500) = $62,500

Your salary will be $62,500.

A function assigns the values. Your salary after completing the 8th year within the company will be $62,500.

A function assigns the value of each element of one set to the other specific element of another set.

Given that the starting salary will be $45,000 while the salary will increase every year by $2,500. Therefore, the function that can represent the salary after (n-1) years can be written as,

y = $45,000 + $2,500(n-1)

Now, the salary after 8th year will be,

y = $45,000 + $2,500(n-1)

y = $45,000 + $2,500(8-1)

y = $62,500

The missing step is the step shown in the last option:

D. [tex]324=0.042x+16[/tex]

To find which is the missing step, we need to remember that to cancel a square root, we need to elevate it, so:

Starting from the last step before the missing step, we have:

[tex]-18=-\sqrt{0.042x+16}[/tex]

In order to calculate the value of the variable (x) we need to square both sides of the equation, since squaring a root will cancel the root.

We must remember the following properties:

[tex]\sqrt{a^{m} }=a^{\frac{m}{2}}\\\\(a^{b})^{c}=a^{b*c}[/tex]

Now, finding the missing step, we need to find what to do in order to get the expression of the following step.

So, squaring both sides of the equation in order to cancel the square root and isolate the variable, we have:

[tex]-18=-\sqrt{0.042x+16}\\\\(-18)^{2} =(-\sqrt{0.042x+16})^{2} \\324=0.042x+16\\324-16=0.042x\\\\x=\frac{304}{0.042}=7333[/tex]

Step-by-step explanation:

look up cylinder formula and r= radius which is just the diameter cut in half

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The volume of the cylinder is 3421.1944 cm³.

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centers overlap each other to form a right cylinder.

Given the diameter of the cylinder is 22 cm, therefore, the radius of the cylinder is 11cm, Also, given the height of the cylinder is 9 cm.

The volume of the cylinder = πR² × H

                                             = π × (11cm)² × 9cm

                                             = 1089π cm³

B. Data set X is not linear, and data set Y is linear.

Step-by-step explanation:

We assume here that "form a pattern" means "roughly forms a line"... because a pattern doesn't necessarily equal a line, it would be a curve that would easily be interpreted too, but it wouldn't be linear.

Since you cannot form a pattern, and based on your choices for answer, we have have to say that data set X is NOT linear.

On the opposite, since the data set Y produces a pattern, it has to be linear.

So, X = NOT linear, Y = linear.

Answer:

The fourth graph (last graph)

Step-by-step explanation:

Remember that the zeros of a function are the x-intercepts of the graph. To find the zeros we just need to set the function equal to zero and solve for x:

[tex]f(x)=(x-1)(x+4)[/tex]

[tex](x-1)(x+4)=0[/tex]

[tex]x-1=0,x+4=0[/tex]

[tex]x=1,x=-4[/tex]

Now we know that the graph or our function intersects the x-axis at x = 1 and x = -4.

Since both x values inside the parenthesis are positive, our parabola is opening upwards.

The only graph opening upwards whose x-intercepts are x = 1 and x = -4 is the fourth one.

We can conclude that the graph of [tex]f(x)=(x-1)(x+4)[/tex] is the fourth one.

ANSWER

See attachment.

EXPLANATION

The given function is

f(x) = (x – 1)(x + 4).

This parabola will open upwards because the leading coefficient is positive.

The x-intercepts can be found by equating the function to zero.

[tex](x - 1)(x + 4) = 0[/tex]

By the zero product property;

[tex]x - 1 = 0 \: or \: x + 4 = 0[/tex]

This implies that,

[tex]x = 1 \: or \: x = - 4[/tex]

The graph that touches the x-axis at -4 and 1, and opens upwards is the last graph.

The correct choice is D.
