Answer:

15km

Step-by-step explanation:

Use the Pythagorean Theorem

a²+b²=c²

9²+12²=c²

81+144=c²

225=c²

Square root both sides

c= 15km

Answer:

d=15

Step-by-step explanation:

So in this question we are using the Pythagorean Theorem. a^2 + b^2 = c^2

The side opposite to the right angle is the hypotenuse.

So to solve the equation put in the values for a and b.

9^2 + 12^2 = c^2

81 + 144 = c^2

225 = c^2

Now take the square root of 225

$\sqrt{225}$ = 15

so d = 15

What are the zeros of f(x) = x3 + 6x2 + 3x – 10 ?

schepotkina [342]

One of the zeroes would be : x = 1

f (1) = 1^3 + 6(1) ^2 + 3 (1) - 10

f(1) = 1 + 6 + 3 - 10

f (1) = 10 - 10

f (1) = 0

Hope this helps

How do you do this question?

Answer:

C) π/6

Step-by-step explanation:

The area under the curve from x=-π/2 to x=k is 3 times the area under the curve from x=k to x=π/2.

$\int\limits^k_{-\frac{\pi }{2}} {cos\ x} \, dx = 3\int\limits^{\frac{\pi }{2}}_k {cos\ x} \, dx\\sin\ x\ |^{k}_{-\frac{\pi }{2}} = 3\ sin\ x\ |^{\frac{\pi }{2}}_k\\(sin\ k - (-1)) = 3\ (1 - sin\ k)\\sin\ k + 1 = 3 - 3\ sin\ k\\4\ sin\ k = 2\\sin\ k = \frac{1}{2}\\k = \frac{\pi}{6}$

Pls help! What's the answer?

Answer:

The answer is b = 8a

Step-by-step explanation:

As, 0 x 8 = 0

2 1/2 = 5/2, 5/2 x 8 = 20

5 x 8 = 40

7 1/2 = 15/2, 15/2 x 8 = 60

10 x 8 = 80

13 1/2 = 27/2, 27/2 x 8 = 108

So all variables "a" when multiplied by 8 will give us the value in "b"

So b = 8a
