marishachu [46]3 years ago
4 0

Answer:

D)

Step-by-step explanation:

y=\frac{-3}{2}x-4

Coefficient of x is -3/2 and so multiply the whole equation by 2

2*y=2*\frac{-3}{2}x-2*4\\\\2y=-3x-8

3x + 2y = -8

The bar of the square pyramid shown has and area of 576 units. If the slant height of the pyramid is 29 units, what is the heigh
Aloiza [94]

Answer:

\sqrt{697}

Step-by-step explanation:

If the base of the square pyramid has an area of 576 units, then the side length must have a length of \sqrt{576}=24. 24/2=12, and using the pythagorean theorem you can find that the height of the pyramid is \sqrt{29^2-12^2}=\sqrt{697}. Hope this helps!

Determine the amplitude, period, and phase shift of the function f(x)=cos (8(x-1))+2​
SCORPION-xisa [38]

We have been given a function f(x)=\text{cos}(8(x-1))+2. We are asked to find the amplitude, period and phase shift of the function

We can see that our given function is in form f(x)=A\cdot \cos(B(x-C))+D, where,

|A| = Amplitude.

Period = \frac{2\pi}{|B|}

C = Horizontal shift,

D = Vertical shift.

We can see that value of a is 1, therefore, the amplitude of given function would be 1.

We can see that B is equal to 8, so we will get:

\text{Period}=\frac{2\pi}{|B|}= \frac{2\pi}{|8|}=\frac{\pi}{4}

Therefore, the period of given function is \frac{\pi}{4}.

Since the value of C is 1, therefore, horizontal shift is 1.

Since the value of D is 2, therefore, vertical shift would be 2.

At Lesile's party 1/4 of the people had long hair. 1/2 of the people were boys, and 1/4 of the girls had short blonde hair. None
dybincka [34]

Answer:

4 girls have short red hair

Step-by-step explanation:

Total number of guests at the party is 32

1/2 of the guests are boys

The number of girls with long hair is

= 32×1/4

= 8 girls.

The number of girls with short blonde hair is:

= 16×1/4

= 4 girls

Therefore, we apply the formular below to calculate the maximum number of girls with short red hair.

Total number of girls- ( girls with long hair+ girls with short blonde hair)

= 16-(8+4)

=16-12

= 4

Thus, 4 girls have short red hair
