Answer:

x=29

Step-by-step explanation:

The sum of angles in a triangle is 180deg.

We know this is a right triangle, so the third angle is 90deg, leaving us with 90deg for the other two.

(2x-2) + (x+5) = 90

3x + 3 = 90

3x = 87

x = 29

Find the volume of the compound shape.

jeyben [28]

<h3>Given:</h3>

Hemisphere ×2 or sphere
Cylinder

<h3>Solution:</h3><h3>Volume of the sphere:</h3>

$v = \frac{4}{3} \pi {r}^{3}$

$v = \frac{4}{3} \times \pi \times {2}^{3}$

$v = 33.51 \: {m}^{3}$

<h3>Volume of the cylinder:</h3>

$v = \pi {r}^{2} h$

$v = \pi \times {2}^{2} \times 6$

$v = 75.40 \: {m}^{3}$

<h3>Total volume:</h3>

$v = 75.40 + 33.51$

$v = 108.91 \: {m}^{3}$

Hence, the volume of the given compound shape is 108.91 cubic meters.

pickupchik [31]

Answer:

52 weeks

Step-by-step explanation:

The club starting with $270 (club 1) is increasing their bank balance each week by ...

... $280 -270 = $10

The club starting with $10 (club 2) is increasing their bank balance each week by ...

... $25 -10 = $15

Club 2 is gaining on Club 1 by $15 -10 = $5 each week. So, the initial difference of $270 -10 = $260 will be overcome in ...

... $260/($5/week) = 52 weeks

_____

The same result is shown in the attached graph, which also shows that both clubs' bank balances will be $790 at that time.

For the functions f(x)=x4−x3−7x2+9x−2 and g(x)=x−1, find (f/g)(x) and (f/g)(2).

Fed [463]

Answer:

(f/g)(x) = x³ - 7x + 2

(f/g)(2) = -4

Step-by-step explanation:

To find (f/g)(x), divide f(x) by g(x). The process is shown in the attached image.

(f/g)(x) = x³ - 7x + 2

To find (f/g)(2), plug in 2 wherever there is an x.

(f/g)(x) = x³ - 7x + 2

(f/g)(2) = (2)³ - 7(2) + 2

(f/g)(2) = 8 - 14 + 2

(f/g)(2) = -6 + 2

(f/g)(2) = -4
