What is the y-intercept of the function f(x) = -3x<br> Ο<br> Ο<br> on who wire on<br> Ο<br> Ο
morpeh [17]

Answer:

see the explanation

Step-by-step explanation:

we know that

The y-intercept is the value of the function when the value of x is equal to zero. Also is called the initial value of the function

I will analyze two cases

Part 1) we have

f(x)=-3x

so

For x=0

substitute

f(0)=-3(0)=0

therefore

The y-intercept is the point (0,0)

Part 2) we have

f(x)=-3^x

so

For x=0

substitute

f(0)=-3^0=-1

therefore

The y-intercept is the point (0,-1)

For my math it says someone ordered a poster with a height of 2 feet and width of 0.7 feet what is the area of the poster
Phantasy [73]
STEP-BY-STEP SOLUTION:

Let's solve this problem step-by-step.

As posters are generally rectangular in shape, we will establish the formula for the area of a rectangle which we will be using as displayed below:

Area = height × width

Now let's find the area of the postwr using the above formula.

Height = 2 feet

Width = 0.7 feet

Area = height × width

Area = 2 × 0.7

Area = 1.4 square feet

ANSWER:

Therefore, the answer is:

The area of the poster is 1.4 square feet.
