Answer:
h ≈ 11.9
Step-by-step explanation:
Since the triangle is right we can use the cosine ratio to find h
cos24° = 
= 
Multiply both sides by 13
13 × cos24° = h
⇒ h = 11.9 cm ( to 1 dec. place )
Answer:
1. x²-2x+15
This can't be factored, I've tried multiple ways now, but it just can't be factored.
2. y²-19y+90
Let's factor y^2−19y+90
y^2−19y+90
The middle number is -19 and the last number is 90.
Factoring means we want something like
(y+_)(y+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -19
Multiply together to get 90
Can you think of the two numbers?
Try -9 and -10:
-9+-10 = -19
-9*-10 = 90
Fill in the blanks in
(y+_)(y+_)
with -9 and -10 to get...
(y-9)(y-10)
Answer:
(y−9) (y−10)
Total cost independent variable
Pounds of candy dependent variable
Step-by-step explanation:
A variable is a condition that is liable to change. Most experimental hypothesis use variables to draw up suitable statements to test.
- An independent variable is that variable that does not rely on another variable. It induces the change or variation in another variable. In the statement above, the total cost is the independent variable.
- The other variable which is the effect resulting from the variation of the independent variable is the dependent variable. Here it is the number of pounds of the candy that changes when total cost varies.
