Answer:

30x^5 + 15x^4 + 105x^3

Step-by-step explanation:

V = l*w*h

l = 3x

w = 5x^2

h = 2x^2 + x + 7

l*w = 3x * 5x^2 = 15x^3 (add exponents when multiplying variables)

l*w = 15x^3

V = l*w*h = 15x^3(2x^2 + x + 7) = 30x^5 + 15x^4 + 105x^3

  • L=3x
  • B=5x^2
  • H=2x^2+x+7[/tex]

\\ \rm\longmapsto V=LBH

\\ \rm\longmapsto V=3x(5x^2)(2x^2+x+7)

\\ \rm\longmapsto V=15x^3(2x^2+x+7)

\\ \rm\longmapsto V=30x^5+15x^4+105x^3

Is the relationship shown by the data linear? x -9, -5, -1, 3 y -2,-7,-12, -17
Temka [501]
                x               y
            ------           -----
              -9              -2
             -5               -7
             -1              -12
              3               -17

ur x's all have a difference of 4, and ur y's all have a difference of -5...so yes, this is linear with a slope of (-7+2) / (-5 + 9) = -5/4

Answer:

FICA tax should his employer withhold be $24.92 .

Option (D) is correct .

Step-by-step explanation:

As given

Bill’s FICA tax is 7.65% of his earnings of 325.78 per week.

7.65 % is written in the decimal form.

= \frac{7.65}{100}

= 0.0765

FICA tax price = 0.0765 × Earning of a week

Putting values in the above

FICA tax price = 0.0765 × 325.78

                         = $ 24.92 (Approx)

Therefore the  FICA tax should his employer withhold be $24.92 .

Option (D) is correct .

D is the midpoint of ec and f is the midpoint of ea ac=14
kati45 [8]

<u>Answer </u>

Option B) 7 is the correct answer  

FD = 7cm

<u>Explanation </u>

Here triangle AEC. D is the midpoint of EC and F is the midpoint of EA

So D and F be the midpoint of triangle AEC.  

FD be the midpoint  joining line.

We know that if any triangle, line joining the midpoint  of two sides is the half of the third side.

Here the third side is 14cm, then FD = 14/2 = 7cm

So option B) is the correct answer.

The point (- 3, 6) is on a circle with a center at (2, 3) What is the equation of the circle?
anzhelika [568]

Answer:

(x - 2)^{2} + (y - 3)^{2} = 36 is the equation of the circle

Step-by-step explanation:

(x - h)^{2} + (y - k)^{2} = r^{2}   where (h, k) is the center and r is the radius

In this case h = 2 and k = 3 and r = 6 (see below)

r adius =

\sqrt{(2 + 3)^{2} + (3 - 6)^{2}  } \\= \sqrt{5^{2} + (-3)^{2} } \\= \sqrt{25 + 9\\}\\ = \sqrt{36}  = 6

Therefore,  (x - 2)^{2} + (y - 3)^{2} = 36 is the equation of the circle
