Answer:

$1343

Step-by-step explanation:

After subtracting 15% from 100% of the original price, the price Mr. Quick paid is 85% of the original price.

0.85 × 1580 = 1343

Mr. Quick paid 1343 for his computer.

What is the length of the tree? Show steps!

Leona [35]

Answer:

The tree is 14 ft. tall.

Step-by-step explanation:

If Ryan is 6 ft. tall and his shadow is 12 ft. tall than his shadow is twice his size. So if the trees shadow is 28 ft. tall then you would divide. Here is the equation:

28 ÷ 2 = 14

To check our work you would do 14 * 2 = 28.

Hope this helps!!

Consider the graph of the cosine function shown below.

nata0808 [166]

Answer:

a. Amplitude: 4

Period: 1

b. The maximum values occur at $\theta=0,1,2$

The minimum values occur at $\theta=\frac{1}{2},\frac{3}{2}$

The zeros occur at $\theta=\frac{1}{4},\frac{3}{4},\frac{5}{4},\frac{7}{4}$

Step-by-step explanation:

We can see from the graph that;

$-4\le f(x) \le 4$ .

This implies that;

$|A|=4$ .

The amplitude is 4.

The function also completed one full cycle on the interval [0,1]

The period is

$T=|1-0|=1$

The maximum values occur at $\theta=0,1,2$

The minimum values occur at $\theta=\frac{1}{2},\frac{3}{2}$

The zeros occur at $\theta=\frac{1}{4},\frac{3}{4},\frac{5}{4},\frac{7}{4}$

This is where the graph intersected the x-axis.

Calcular el volumen en m3 de la esfera en el que el área de uno de sus círculos maximos es 36pim2

Strike441 [17]

Answer:

The volume of the sphere is $V=288\pi\ m^3$

Step-by-step explanation:

<u><em>The question in English is</em></u>

Calculate the volume in m^3 of the sphere in which the area of one of its maximum circles is 36pi m^2

we know that

The radius of the maximum circle in the sphere is equal to the radius of the sphere

Step 1

Find the radius of the maximum circle

The area of the circle is

$A=\pi r^{2}$

we have

$A=36\pi\ m^2$

substitute and solve for r

$36\pi=\pi r^{2}$

Simplify

$36=r^{2}$

take the square root both sides

$r=6\ m$

Step 2

Find the volume of the sphere

The volume of the sphere is

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

substitute the value of r

$V=\frac{4}{3}\pi (6)^{3}$

$V=288\pi\ m^3$
