Answer:

[tex]\large\boxed{L.A.=153\pi\ mm^2}\\\boxed{S.A.234\pi\ mm^2}[/tex]

Step-by-step explanation:

The formula of a lateral area of a cone:

[tex]L.A.=\pi rl[/tex]

r - radius

l - slant height

The formula of a surface area of a cone:

[tex]S.A.=\pi r^2+\pi rl[/tex]

We have r= 9mm and l = 17mm. Substitute:

[tex]L.A.=\pi(9)(17)=153\pi\ mm^2[/tex]

[tex]S.A.=\pi(9^2)+153\pi=81\pi+153\pi=234\pi\ mm^2[/tex]

Answer:

y=15

Step-by-step explanation:

The formula for direct variation is

y = kx

5 =k*2

Solve for k

Divide by 2

5/2 = k

y = 5/2 x

Now we substitute x=6

y = 5/2(6)

y = 15

Answer:

y = 15

Step-by-step explanation:

If the variables are directly proportional, increasing one by a factor of 3 will mean the other one also increases by a factor of 3.

6 is 3 times 2, so the value of y will be 3 times 5, or 15.

___

You can write the relation as a proportion:

y/x = 5/2 = ?/6

Multiplying by 6 gives ...

(5/2)·6 = ? = 15

___

Or, you can bother with an equation relating x and y:

y = kx

5 = k·2 . . . plug in the given values and solve for k

5/2 = k . . . divide by 2

Then ...

y = (5/2)·6 = 15 . . . . same as the proportion, above.

If you rearrange this to y = 5·(6/2) then you see the relation described at the beginning of this solution. The new value of y is the old value multiplied by the factor by which x changes.

Answer:

1.5 times

Step-by-step explanation:

6.75/4.5 = 1.5

To find out how many times longer Mike's ride was than Noah's, you first need to convert the mixed fractions to improper fractions. Then you divide the length of Mike's ride by Noah's ride length. The result is 1.5, meaning Mike’s bike ride was 1.5 times longer than Noah’s.

This problem falls under the category of division of fractions. The question is asking for how many times longer Mike's ride was than Noah's. In order to do this, we must divide the length of Mike's ride by the length of Noah's ride.

First, we convert the mixed fractions to improper fractions. Mike biked 6 3/4 = 27/4 miles, and Noah biked 4 1/2 = 9/2 miles.

To find how many times longer Mike's ride was than Noah's, we divide 27/4 by 9/2. This is equivalent to multiplying 27/4 by the reciprocal of 9/2 (which is 2/9).

When we perform this multiplication, we get (27/4) * (2/9) = (27 * 2) / (4 * 9) = 54 / 36. The result is 1.5, so this means Mike’s bike ride was 1.5 times longer than Noah’s bike ride.

For this case we must find the inverse of the following function:

[tex]f (x) = - \frac {1} {2} \sqrt {x + 3}[/tex]

We follow the steps below:

Replace f(x) with y:

[tex]y = -\frac {1} {2} \sqrt {x + 3}[/tex]

We exchange the variables:

[tex]x = - \frac {1} {2} \sqrt {y + 3}[/tex]

We solve for "y":

[tex]- \frac {1} {2} \sqrt {y + 3} = x[/tex]

Multiply by -2 on both sides of the equation:

[tex]\sqrt {y + 3} = - 2x[/tex]

We raise both sides of the equation to the square to eliminate the radical:

Answer:

The common ratio for the given geometric sequence is -1/2.

Step-by-step explanation:

The common ratio in a geometric sequence is simply the number that multiplies one term to arrive at the next term. From the sequence given, we can let the common ratio be x and determine its value using any of the following set of equations;

1/2 * x = -1/4

-1/4 * x = 1/8

1/8 * x = -1/16

using the first equation;

1/2 * x = -1/4

we divide both sides by 1/2 to solve for x.

x = (-1/4)/(1/2)

x = -1/4 * 2

x = -1/2

Thus, the common ratio for the given geometric sequence is -1/2.  

Answer:

Common ratio is -1/2

Step-by-step explanation:

Common ratio is the amount between each number in a geometric sequence.

It is called the common ratio because it is the same to each number.

Common ratio is the ratio between two successive numbers in a geometric sequence.

x^2 = x3

x^2 - 3x = 0

x(x - 3) = 0

x = 0 and x -3 = 0 or x = 3

x cannot equal zero, therefore the answer is three

The numbers that when squared equal to three times themselves are 0 and 3. This is found by solving the quadratic equation x² = 3x, which factors to x(x - 3) = 0.

To express this mathematically, we let 'x' represent the number, so the equation becomes x² = 3x. This is a quadratic equation that can be solved by rearranging the terms and factoring, resulting in x(x - 3) = 0. Applying the Zero Product Property, we have two potential solutions for x: 0 or 3. Therefore, the numbers that fit the condition are 0 and 3.

[tex] {x}^{2} + 6x - 7 = (x + 3) {}^{2} - (3) {}^{2} - 7 \\ = (x + 3) {}^{2} - 16[/tex]

The equation x^2 + 6x - 7 can be written in the form (x+a)^2 + b as (x + 3)^2 - 16 by completing the square.

To solve this, we will complete the square for the polynomial x^2 + 6x - 7. The equation (x+a)^2 + b involves squaring a binomial (x+a) and adding a constant. Completing the square can convert x^2 + 6x - 7 to this form.

Step 1: Half of the coefficient of x is (6/2)=3 so a=3. Then we square a to get a^2 = 9.

Step 2: We adjust the original equation by subtracting and adding a^2 within it: (x^2 + 6x + 9) - 9 - 7.

Step 3: Simplify the equation to get (x + 3)^2 - 16, which is the form we desired.

It was given that: the volume is 2,279.64 in³

The height of the cylinder is also given as: h=18 in.

We substitute, the given values into the formula to get:

[tex]2279.64= \frac{1}{3} \times (3.14) \times {r}^{2} \times 18[/tex]

[tex]2279.64= 18.84 {r}^{2} [/tex]

[tex] {r}^{2} = \frac{2279.64}{18.84} [/tex]

[tex] {r}^{2} = 121[/tex]

We take positive square root to get;

[tex]r = \sqrt{121} [/tex]

[tex]r = 11in[/tex]

Answer:

B

Step-by-step explanation:

The range is the set of y-values for which the function is defined.

** Attached is the graph of the function

By looking at the graph, we can clearly see that there aren't any y-values that is not permitted in the graph. The function is defined for all y-values. Hence the range is set of all real numbers, or, the range is (-∞, +∞)

Answer choice B is right.

Final answer:

The range of the reciprocal function 1/x is all real numbers except zero, expressed in interval notation as (-∞, 0) ∪ (0, +∞).

Explanation:

The range of the reciprocal function, which is denoted as 1/x, can be understood by considering the behavior of the function as x approaches different values. As x approaches zero from the positive side (x → 0+), the reciprocal 1/x becomes increasingly larger, theoretically 'going to infinity' (∞). Similarly, as x approaches zero from the negative side (x → 0-), 1/x becomes increasingly negative, 'going to negative infinity' (-∞). Thus, the range of the reciprocal function excludes zero, but includes all other real numbers. In interval notation, the range is expressed as (-∞, 0) ∪ (0, +∞).

Answer:

Option D. [tex]\$6,139.25[/tex]

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

[tex]t=4\ years\\ P=\$5,350\\ r=0.035\\n=1[/tex]  

substitute in the formula above  

[tex]A=\$5,350(1+\frac{0.035}{1})^{1*4}[/tex]

[tex]A=\$5,350(1.035)^{4}=\$6,139.25[/tex]

Final answer:

The future amount of money in the account after 4 years with annual compound interest is approximately $6,139.25, which is option D.

Explanation:

The student's question pertains to the calculation of compound interest over a period of 4 years on a principal amount at a given interest rate. To calculate compound interest, we use the formula A = P(1 + r)^n, where A is the total amount after n periods, P is the principal amount, r is the annual interest rate (as a decimal), and n is the number of years the money is compounded. Applying this formula:

P = $5,350 (the principal amount)

r = 0.035 (since 3.5% as a decimal is 0.035)

n = 4 (compounding for 4 years)

Using the formula:

A = $5,350(1 + 0.035)^4

A = $5,350(1.035)^4

A = $5,350 * 1.14888281

A ≈ $6,139.25

Thus, the amount of money in the account at the end of 4 years, with compound interest, will be approximately $6,139.25, which corresponds to option D.
