Answer:
f(x) = 0.5(x + 3)^2 + 5.
Step-by-step explanation:
The horizontal stretch is given by multiplying by 1/2 or 0.5:
f(x) = 0.5x^2
Now a shift of 3 to the left gives f(x) = 0.5(x + 3)^2.
5 units up gives 0.5(x + 3)^2 + 5.
Answer:
where are the choices
Step-by-step explanation:
?
well, we know the shaded region has an area of 5x²+3x-4, there are three more sections of equal shape, so their areas must also be equal, meaning there are four regions of the same area of 5x²+3x-4, thus 4(5x²+3x-4) = 20x²+12x-16.

Answer:</h2>
The number of kilograms a 19 m beam can support is:
378.9474 kg
<h2>
Step-by-step explanation:</h2>
It is given that:
The weight W that a horizontal beam can support varies inversely as the length L of the beam.
Let k denote the constant.
This means that the weight W and Length L is related as:

Suppose that an 8 dash m beam can support 900 kg.
This means that L=8 and W=900
Then,

Now , we are asked to find the value of W when L= 19
i.e.
