Answer:
Step-by-step explanation:
Start by moving the 3 to the other side of the equals sign to get

so with that replacement:

By the Zero Product Property,
or 
Yes these are both the same, so we only need one of them. Once we find the angle, they are both the same, so we only need one of these equations.
If
, take the inverse tangent of both sides to give you:
and
so

Tangent increases in increments of pi or 180, so the other angle within the given interval is 35.8 + 180 = 215.8
Answer:

Step-by-step explanation:
Given the dimensions of the cylinder as d=4cm and h=4cm, its volume can be calculated using the formula:

Hence the volume of the cylinder is 50.27
About Slope Intercept Form:
- y = mx + b
- m is the slope
- b represents the y-intercept
For the graphing one, since the slope is positive, you have to go up 5 and right 2 because the slope equals <u>rise</u>
run.
5 represents rise & 2 represents run. Then -4 is the starting point, the y-intercept.
Hope this info helps!! :)
Answer:
D) The function is always decreasing
Step-by-step explanation:
As you move along the x axis, the x value approaches: a) negative infinity when x < 0 and b) 0 when x > 0
Answer:
Julie can buy 4 plants
Step-by-step explanation:
A plant costs £6.80 and Julie has £30.
In order to find out how many plants she can buy with £30, we need to see how much times £6.80 can go into £30. In other words, we need to divide £30 by £6.80 so we get the number times it can go into £30. That will be the number of plants.
£30 ÷ £6.80 = 4.41176470588
Julie can't get 0.41176470588 of a plant so we have to round it to 4. She can buy 4 plants.
She has a bit of money left over (you can tell by the decimal number), but that isn't enough to buy another plant. So she buys 4 and has £2.80 left.
£6.80 x 4 = £27.20
