Answer:

2a) x=40.44, y=2.816

Step-by-step explanation:

2a)

Use SOHCAHTOA. You have the opposite (2.4) and the hypotenuse (3.7)

so you use SOH, which means sin(x) = opposite/hypotenuse

so x = sin⁻¹ (2.4 / 3.7) ≈ 40.44.

To find y, we use, CAH: cos(x) = y / hypotenuse

y = cos(x) * hypotenuse = cos(40.439793) * 3.7 ≈ 2.816

Maria practice the piano 5/6 of an hour everyday. How many hours does she practice in 4 days
S_A_V [24]
Answer:
10/3 hours

If Maria practices 5/6 hours a day, then she practices (5/6)(4) hours in 4 days.

(5/6)(4)=20/6

20/6 can be simplified to 10/3 hours.

I hope this helps!

Round off 0.043 to one significant figure
aniked [119]
Hey there :)

0.043
The first 0 before the decimal point is not significant since it is used for cosmetic purpose
The 0 after the decimal is not significant as the 0 is used to locate the decimal point
The 4 is the first nonzero integer and it counts as a significant figure

Therefore, 0.04 will be your answer rounded to 1 s.f

F(x) = x ^ 2 . What is g(x) ?
Bond [772]

Given:

The function is:

f(x)=x^2

The graphs of functions f(x) and g(x).

To find:

The function g(x).

Solution:

We have,

f(x)=x^2

The function f(x) is vertically compresses to get the graph of the function g(x). So, the function g(x) is:

g(x)=kf(x)

g(x)=kx^2               ...(i)

From the given graph it is clear that the graph of the function g(x) passes through the point (3,3). So, putting x=3 and g(x)=3 in the above function, we get

3=k(3)^2

3=9k

\dfrac{3}{9}=k

\dfrac{1}{3}=k

Putting k=\dfrac{1}{3} in (i), we get

g(x)=\dfrac{1}{3}x^2

Therefore, the correct option is D.
