Answer:

Step-by-step explanation:

V = (4 * pi /3) * (38 + 0.16t)^3

t = 208 seconds.

V = (12.56/3) * (38 + 0.16 * 280)^3

V = 4.186 * ( 38 + 44.8)^3

V = 4.286 * (82.8)^3

V = 4.286 * 567663

V = 2433005 which is close enough. The precise answer will be obtained by using a better value for pi. Anyway that's the only answer that gives about 2.5 million so B is correct.

20 points!! Solve this system of lineal equations.separate the x- and y- values with a comma

Zielflug [23.3K]

Solve the following system:{12 x = 54 - 6 y | (equation 1)-17 x = -6 y - 62 | (equation 2)
Express the system in standard form:{12 x + 6 y = 54 | (equation 1)-(17 x) + 6 y = -62 | (equation 2)
Swap equation 1 with equation 2:{-(17 x) + 6 y = -62 | (equation 1)12 x + 6 y = 54 | (equation 2)
Add 12/17 × (equation 1) to equation 2:{-(17 x) + 6 y = -62 | (equation 1)0 x+(174 y)/17 = 174/17 | (equation 2)
Multiply equation 2 by 17/174:{-(17 x) + 6 y = -62 | (equation 1)0 x+y = 1 | (equation 2)
Subtract 6 × (equation 2) from equation 1:{-(17 x)+0 y = -68 | (equation 1)0 x+y = 1 | (equation 2)
Divide equation 1 by -17:{x+0 y = 4 | (equation 1)0 x+y = 1 | (equation 2)
Collect results:Answer: {x = 4 {y = 1

Please note the { are supposed to span over both equations but it interfaces doesn't allow it. Please see attachment for clarification.

Given f(x) = 2x – 3, find the x value such that f(x) = 8.

jok3333 [9.3K]

Answer: 5.5

Step-by-step explanation:

Plugging it into the formula, we get

2x-3 = 8

Add 3 to both sides:

2x = 11

Divide by 2 on both sides:

x = 5.5

Which expression is equivalent to 10x2y + 25x2?

babymother [125]

$10 x^{2} y +25 x^{2} = 5 x^{2} ( \frac{10 x^{2} y +25 x^{2} }{5 x^{2} }) = 5 x^{2} ( \frac{10 x^{2} y}{5 x^{2} } + \frac{25 x^{2} }{5 x^{2} } ) = 5 x^{2} ( \frac{2y}{1} + \frac{5}{1} )$

Answer A 5x² * ( 2y + 5)

Steve puts an 18-foot ladder against his house. The ladder reaches a height of 15 feet on the house. How far is the bottom of th

krek1111 [17]

Answer:

$3 \sqrt{11}$

Step-by-step explanation:

Since we are given the hypotenuse which is 18 since it slanted, and leans on the house. And we are given one of the legs which is 15 since it is vertical. We can use the pythagorean theorem to solve for this problem.

${a}^{2} + {b}^{2} = c {}^{2}$
