Answer:
1st graph.
Step-by-step explanation:
The function y = -x² + 5, reflects the 1st graphic.
Reasoning:
- If we make x equal to 0, y=5, it meas the parabole crosses y-axis at 5.
- In every quadratic function, if the value of x is negative, the parabole goes downwards.
Answer is d) 20 cubic millimeters and I showed working in the pic
Answer:
C. 176.6 Square feet (I think)
Step-by-step explanation:
I tried many different ways and got three of the answers above but I think this is the right one.
The equation to find area of a circular cone base: 
- We are given the diameter (15 Feet) but we need to find the radius. So we use the diameter to radius formula:
- Plug in numbers:
≈ 
- Use the Area formula now that you have radius:
- Solve and get =
- Looking at the options the closest one to our answer (off by one-tenth) is C.
Sorry if you get this wrong. I tried lol.
We need to use the formula for simple interest which is
I= prt
Where I is the amount of money you earned or pay in interest
p is the principal, the amount you deposited or borrowed
r is the interest rate expressed as a decimal
t is time in terms of years
In this problem, I= 1,680
p= 3000
t= 8
'. r is what we are looking for.
Substituting the numbers into the simple interest formula, we get
I=. p r t
1,680=(3000)(r)(8). Multiplying
1,680= 24,000r Divide both sides by 24,000
0.07= r
So, the percentage is (0.07)(100)= 7%...
