Answer:

The expression for length of the rectangle is x-2 meters.

Step-by-step explanation:

Given the area of the rectangle as : x²- 7x+10 square meters

The width of the rectangle is : x-5 meters

Area of a rectangle is given by the product of its length and width.

Dividing the expression for area with the expression for width will give the expression for length.

Here, perform the long division of the polynomial; where the numerator is  x²- 7x+10 and the denominator is x-5

First divide  x²- 7x+10 by x-5 to get x

Multiply x by x-5 to get x²-5x

Subtract x²-5x from x²-7x+10 to get  -2x+10

Then divide -2x+10 by x-5 to get -2

Multiply x-5 by -2 to get -2x+10

Perform subtraction to remain with zero.

The expression for length will now be x-2 meters

Step-by-step explanation:

5) Volume  = Volume of rectangular prism 1  + volume of rectangular prism2

 =  10* 6 * 4 +  (7*4*2)

 = 240 + 56

 = 296 cm³

6) Volume = (5*6*8) + (9*6*2)

                  = 240 + 108

                   = 348 ft³

7) Volume = (11*12*4) + (5*5*12)

                 = 528 + 300

                 = 828 m³

Answer:

h=m+43, 66cm

Step-by-step explanation:

For each month, it grows by one centimeter, which is represented by 1m or just m. You also have to add the height it already has, which makes h=m+43. For 21 months, substitute 21 for m to get h=21+43 which simplifies into h=66 cm

Answer:

1.68 seconds.

Step-by-step explanation:

The question, is, essentially asking for time, t, at position 325 feet.

So:

Set h(t) equal to 325.

325 = 16t^2 + 168t + 5

Subtract 325 over, to get the quadratic:

0 = 16t^2 + 168t - 320

Factor out an eight, simply to make the equation easier:

0 = 2t^2 + 21t - 41

Now, use the quadratic formula to find the "zeros", or solutions:

{-21 + (21^2 - [(4)(2)(-41)]^.5}/(2)(2); {-21 - (21^2 - [(4)(2)(-41)]^.5}/(2)(2)

Simplify:

(-21 + [441 + 328]^.5)/4; (-21 - [441 + 328]^.5)/4

(-21 + [769]^.5)/4; (-21 - [769]^.5)/4

(-21 + 27.73)/4; (-21 - 27.73)/4

(6.73)/4; (-48.73/4)

t = 1.68, -12.18

It makes no sense for t to be negative, since t represents time.

Therefore, the potato is 325 feet in the air after 1.68 seconds.

I hope this helped! :)

The potato is 325 feet in the air after 1.68 seconds on the way back down.

The quadratic function is defined as a function containing the highest power of a variable is two.

The question is effectively inquiring about time, t, at 325 feet.

Set h(t) equal to 325.

325 = 16t² + 168t + 5

Subtract 325 over, to get the quadratic:

0 = 16t² + 168t - 320

Factor out an eight, simply to make the equation easier:

0 = 2t² + 21t - 41

2t² + 21t - 41 = 0

Compare the given function to the standard quadratic function f(x) = ax² + b x + c.

We get a = 2, b = 2 and c = -12

Now, use the quadratic formula to find the "zeros", or solutions:

[tex]\quad x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]t=\dfrac{-21\pm \sqrt{21^2-4\cdot \:2\left(-41\right)}}{2\cdot \:2}[/tex]

[tex]\sqrt{21^2-4\cdot \:2\left(-41\right)}[/tex]

[tex]=\sqrt{21^2+328}[/tex]

t = (-21 + 27.73)/4; (-21 - 27.73)/4

t = (6.73)/4; (-48.73/4)

t = 1.68, -12.18

Because t symbolizes time, it makes no sense for it to be negative.

As a result, after 1.68 seconds, the potato is 325 feet in the air.

Answer:

$512.67 (surplus)

Step-by-step explanation:

Monthly fixed expenses = $3,900

Monthly living expenses = $676

Monthly annual expenses = $561

⇒ Total monthly expenses = 3900 + 676 + 561 = $5,137

Annual net income = $67,796

⇒ Monthly net income = $67,796 ÷ 12 = $5,649.67

Monthly budget = Monthly net income - Total monthly expenses

                           = $5,649.67 - $5,137

                           = $512.67 (surplus)

Answer:

can u please tell what is 158° here

Answer:

x = 11

Step-by-step explanation:

the inscribed angle CDE is half the measure of its intercepted arc CE , so

8x - 9 = [tex]\frac{1}{2}[/tex] × 158 = 79 ( add 9 to both sides )

8x = 88 ( divide both sides by 8 )

x = 11

Answer:

0.02835

Step-by-step explanation:

Let p be the probability who are in favor of the project and q be the probability who are not in favor of the project.

p = 30% = 0.30

q = 1 - p = 1 - 0.30 = 0.70

n = 5, x = 4

Now, by binomial distribution formula:

[tex]P(X=x)=^nC_x \:p^x \:q^{n-x}[/tex]

[tex]\implies P(X=4)=^5C_4\: (0.30)^4\: (0.70)^{5-4}[/tex]

[tex]\implies P(X=4)=5 (0.30)^4 \:(0.70)^{1}[/tex]

[tex]\implies P(X=4)=5 (0.0081) \:(0.70)[/tex]

[tex]\implies P(X=4)=0.02835[/tex]

The probability that exactly 4 of them favor the new building project is 0.02835.

Answer:

2/3 = 8/12

1/4 = 3/12

Step-by-step explanation:

2/3

12/3 = 4, so for the fraction 2/3, we multiply the numerator and denominator by 4.

2/3 = 8/12

1/4

12/4 = 3, so for the fraction 1/4, we multiply the numerator and denominator by 3.

1/4 = 3/12

Answer:

[tex]\frac{8}{12}[/tex] and  [tex]\frac{3}{12}[/tex]

Step-by-step explanation:

To do this, you must multiple the numerator and denominator of each fraction by whatever number gives you 12 on bottom.

for [tex]\frac{2}{3}[/tex] , you would multiply it by 4 since 4×3=12. You would also need to multiply the top by 4, making that fraction [tex]\frac{8}{12}[/tex]

For [tex]\frac{1}{4}[/tex] , multiply it by 3, which would equal [tex]\frac{3}{12}[/tex]
