Answer:

Since you want me to answer 3 lb 1 oz - 1 lb 15 oz instead, the answer is 18 oz

Step-by-step explanation:

First, convert pounds and ounces to just ounces, then subtract the total ounces. Finally, convert back to pounds and ounces to get the result of 8 lb 1 oz minus 3 lb 6 oz, which is 4 lb 11 oz.

Subtracting Mixed Measurements

To find the result of 8 lb 1 oz − 3 lb 6 oz, follow these steps:

Convert everything to ounces for easier subtraction (since there are 16 ounces in a pound).

Subtract the ounces first, then subtract the pounds.

Step-by-Step Solution

Step 1: Convert to ounces
8 lb 1 oz = (8 × 16) + 1 = 128 + 1 = 129 ounces
3 lb 6 oz = (3 × 16) + 6 = 48 + 6 = 54 ounces

Step 2: Subtract the ounces
129 ounces - 54 ounces = 75 ounces

Step 3: Convert back to pounds and ounces
75 ounces = 4 lb 11 oz (since 75 ÷ 16 = 4 remainder 11)

Therefore, 8 lb 1 oz − 3 lb 6 oz = 4 lb 11 oz.

Step-by-step explanation:

given x² - 6x - 21 = 0 ( add 21 to both sides )

x² - 6x = 21

to complete the square

• add ( half the coefficient of the x-term)² to both sides

x² + 2 (- 3)x +9 = 21 + 9

(x - 3)² = 30 ( take the square root of both sides )

x - 3 = ± [tex]\sqrt{30}[/tex] ( add 3 to both sides )

x = 3 ± [tex]\sqrt{30}[/tex]

x = 3 - [tex]\sqrt{30}[/tex] = - 2.48 ( to 2 dec. places ) or

x = 3 + [tex]\sqrt{30}[/tex] = 8.48 ( to 2 dec. places )

Answer:

df/dx = e^x(1/x+ ln(x))

Step-by-step explanation:

f(x) = e^x * ln(x)

We can solve this by partial derivatives

df/dx = u dv + v du

let u = e^x and v = ln(x)

df/dx = e^x * 1/x + ln(x) * e^x

Factor out the e^x

df/dx = e^x(1/x+ ln(x))

Answer:

D

Step-by-step explanation:

The quadratic formula is

[tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex].

It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions.  Using the formula will require less work than finding the factors if factorable. We will substitute a=2, b=16 and c=-9.

[tex]x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}\\x=\frac{-(16)+/-\sqrt{(16)^2-4(2)(-9)} }{2(2)}\\x=\frac{-16+/-\sqrt{256+72} }{4}[/tex]

We will now simplify and solve.

[tex]x=\frac{-16+/-\sqrt{328}}{4}\\x=-4+/-\sqrt{\frac{328}{16}}\\x=-4+/-\sqrt{\frac{41*8}{2*8}}\\x=-4+/-\sqrt{\frac{41}{2}}[/tex]

Answer:

B

Step-by-step explanation:

f(x) = [tex]x^{2} -8x+3[/tex]

=> f(x)= [tex]x^{2} -2(x)(4)+4^{2}-4^{2}+3[/tex]

=> f(x) = [tex](x-4)^{2}-4^{2}+3[/tex]

=> f(x) = [tex](x-4)^{2}-16+3[/tex]

=> f(x) = [tex](x-4)^{2}-13[/tex]

Answer:

f(x) = (x - 4)² - 13

Step-by-step explanation:

f(x) = x² − 8x + 3

x² − 8x + 3 = 0

x² - 8x = -3

x² - 8x + 4² = -3 + 4²

x² - 8x + 4² = -3 + 16

x² - 8x + 4² = 13

(x - 4)² = 13

(x - 4)² - 13 = 0

The vertex form of a quadriatic function  f(x) = x2 − 8x + 3 is;

f(x) = (x - 4)² - 13

Final answer:

To find the measure of angle K in the isosceles trapezoid JKLM, set the expressions for angle J and angle M equal to each other and solve for x. Substituting the value of x into one of the angle expressions will give the measure of angle K.

Explanation:

To find the measure of angle K in the isosceles trapezoid JKLM, we can use the fact that the opposite angles in an isosceles trapezoid are congruent. Since angle J and angle M are given in terms of x, we can set them equal to each other and solve for x:

17x + 7 = 11x + 13

Simplifying the equation, we get:

6x = 6

x = 1

Now that we have the value of x, we can substitute it back into one of the angle expressions to find the measure of angle K:

m∠K = 17(1) + 7 = 24 degrees

Answer:

C. 81[-4/3]^n-1

Step-by-step explanation:

The explicit formula for a geometric sequence is given by a_n = a * r^(n-1). Using the provided values of a2 = 108 and a5 = 256, we can establish two equations to solve for 'a' and 'r'. This results in two possible explicit formulas for the sequence.

In a geometric sequence, each term after the first is obtained by multiplying the previous term by a fixed, non-zero number called the common ratio. If we denote the first term of the sequence by 'a' and the common ratio by 'r', then the explicit formula of the sequence is: a_n = a * r^(n-1). Given that a2 = 108 (the second term is 108) and a5 = 256 (the fifth term is 256), we have two equations: a*r = 108 and a*r^4 = 256. Dividing the second equation by the square of the first equation, we get r^2 = 256/108^2 = 0.022. So, r is about +- 0.148. Substituting r into the first equation, we can solve for a. This gives us two possible explicit formulas for the sequence depending on whether we take the positive or negative value of r.

Answer:

[tex]a= \frac{-52-b}{4}[/tex]

Step-by-step explanation:

Rearrange the equation so b is the independent variable.

To get 'b' as a independent variable , we need to get 'a' alone

WE need to solve for 'a' so that 'a' depends on variable b and 'b' becomes independent variable

4a+b=−52

To get 'a' alone , subtract 'b' from both sides

4a = -52-b

Divide by 4 on both sides

Answer:

Running rate of Destiny is 15 kmph

Step-by-step explanation:

Running rate of Destiny is the speed at which Destiny is running.

It can be calculated by finding the difference in the distance covered to the difference in the time taken.

So,

Running rate = Difference in distance covered / Difference in time taken

Difference in distance covered = 5-3 = 2 km

Difference in time taken = 10:44 am - 10:36 am = 44 -36 minutes = 8 mins =8/60 hour = 2/15 hour

Running rate = 2/(2/15) kmph =(2*15)/2 = 15 kmph

∴Running rate of Destiny is 15 kmph

Final answer:

To find the equation of the circle, we need the center coordinates and the radius. In this case, the center is (3, -2) and the circle passes through the point (0, 2). Using the distance formula, the radius is found to be 5. Therefore, the equation of the circle is [tex](x - 3)^2 + (y + 2)^2 = 5^2[/tex].

Explanation:

To find the equation of a circle, we need the center coordinates and the radius. In this case, the center is (3, -2) and the circle passes through the point (0, 2). We can use the distance formula to find the radius, which is the distance between the center and the point on the circle.

Using the distance formula, [tex]d = \sqrt{((x2 - x1)^2 + (y2 - y1)^2)[/tex], we have:

[tex]d = \sqrt{((0 - 3)^2 + (2 - (-2))^2)} = \sqrt{((-3)^2 + (4)^2)} = \sqrt{(9 + 16)} = \sqrt{(25)} = 5[/tex]

So, the radius is 5. Therefore, the equation of the circle is

[tex](x - 3)^2 + (y + 2)^2 = 5^2[/tex]

To find the equation of the circle with center at (3, -2) and passing through the point (0, 2), use the standard form and calculate the radius. Then, the equation is (x - 3)² + (y + 2)² = 25.

To find the equation of a circle with center at (3, -2) and passing through the point (0, 2), we can use the standard form of the equation of a circle, which is:

(x - h)² + (y - k)² = r²

Here, (h, k) is the center of the circle, and r is the radius. Given the center (3, -2), we substitute h = 3 and k = -2:

(x - 3)² + (y + 2)² = r².

Next, we find the radius by calculating the distance between the center (3, -2) and the point (0, 2) using the distance formula:

r = [tex]\sqrt{(0 - 3)^2 + (2 + 2)^2}[/tex]

= √(9 + 16)
= √(25)
= 5.

With r = 5, we can now write the full equation of the circle:

(x - 3)² + (y + 2)² = 25

To summarize, the equation of the circle with center at (3, -2) and passing through the point (0, 2) is (x - 3)² + (y + 2)² = 25.

Answer:

∠CAT = 140°

Step-by-step explanation:

Since AB bisects ∠CAT then ∠BAT = ∠CAB, hence

5x + 20 = 2x + 50 ( subtract 2x from both sides )

3x + 20 = 50 ( subtract 20 from both sides )

3x = 30 ( divide both sides by 3 )

x = 10

∠CAT = ∠BAT + ∠CAB = 5x + 20 + 2x + 50 = 7x + 70

substitute x = 10 into the expression

∠CAT = (7 × 10) + 70 = 70 + 70 = 140°

The correct answer option is A. x2 – 3x + 15.

Step-by-step explanation:

We are given the following expression and we are supposed to simplify it:

[tex]7x^2+6x-9x-6x^2+15[/tex]

Before solving it, a good idea will be to arrange all the like terms together in their decreasing power and write the expression as:

[tex]7x^2-6x^2+6x-9x+15[/tex]

Simplifying it to get:

[tex]x^2-3x+15[/tex]

Therefore, the first option A is the correct answer x2 – 3x + 15.

Answer:

A. [tex]x^{2} - 3x +15[/tex]

Step-by-step explanation:

Given:

7x^2 + 6x – 9x – 6x^2 + 15.

On combining the x^2, and "x" terms we get,

= (7x^2 – 6x^2) + (6x – 9x)  + 15

Now, here simple addition of integers takes places

=  x^ - 3x + 15

20h   =    195

20            20

h       =     9.75

Answer:

30% of the meat on the platter is ham.

Step-by-step explanation:

90 slices = 100%

10% = 9 slices

90 - 63 = 27 slices (this is the amount of ham)

10% x 3 = 30% = 27 slices of ham

Answer:

27 slices of ham which is about 30% of the meat.

Step-by-step explanation:

In this problem we have given

no. of slices of meat=90

no of slices of turkey's meat=63

Percent of ham in platter=?

No of ham slices= Total slices -turkey slices

=90 - 63

= 27 slices

therefore no of ham slices=27

percent of ham slices=Ham slicesx100/total slices

=27x100/90%

=30%

Therefore  percent of ham's in patter=30%
