How do i slove for x2 + 19 = 3
Answer:
x = ± 4i
Step-by-step explanation:
x^2 + 19 = 3
Subtract 19 from each side
x^2 +19-19 = 3-19
x^2 = -16
Take the square root of each side
sqrt(x^2) = sqrt(-16)
x = sqrt(-1*16)
x =sqrt(-1) * sqrt(16)
We know that the square root of -1 is the imaginary number i
x = ± 4i

Pickle cannot get the cart up the ramp. In order to be successful he should
make the ramp longer.
make the ramp shorter.
make the ramp steeper.
back up and begin with a running start.
Answer: Make the ramp longer
making the ramp shorter and making the ramp steeper would be the same, and backing up wouldn't really help
Pickle should make the ramp longer in order to be successful.
Option A is the correct answer.
What is a ramp?The ramp refers to a sloped surface that connects a lower level to a higher level.
We have,
- A longer ramp will provide a more gradual slope, which will make it easier for the cart to move up the ramp.
- If the ramp is too short,
The slope will be too steep and it will be difficult to push the cart up.
- Making the ramp steeper will also make it more difficult to push the cart up.
- Starting with a running start may provide some initial momentum, but it will not address the underlying problem of the ramp being too short.
Thus,
Pickle should make the ramp longer in order to be successful.

B. The measure of angle AGB is greater than the measure of angle AED.
C. Segment AE and Segment AB have the same length.
D. The ratio of AG to AE is the same as the ratio of AB to AD.
Answer:
D
Step-by-step explanation:
....iam not sure but i think its a because the other impossible
Answer:
The answer is D.
Step-by-step explanation:
For A- I don't think it's greater, I think they are the same.
For B- I don't think it's greater, I think they are the same.
For C- Segment AE is longer than Segment AB.
So D seems like the more logical answer.

A restaurant is making table cloths for their four round tables. Each table is a circle with a radius of 2 ft. Each table cloth needs to be 20% larger than the table surface.
How many whole table cloths can the restaurant get out of a piece of fabric with an area of 64 ft²?
Please help!!
Answer:
4
Step-by-step explanation:
Since it gives us the amount of area of material to use we know we want to find how many times we can divide it into tablecloths. So now we need to find how much each tablecloth is.
so first it tells us that each table has a radius of 2 ft, so we find the area using that. area of a circle is [tex]\pi r^2[/tex] so plugging in 2 ft we get 4π square feet or 12.56.
It also says that each tablecloth needs to be 20% bigger, so we find what 20% larger than 4π is. to do this you do 4pi*1.2 = 4.8π = 15.072 square feet.
Now, how many tablecloths with areas of 15.072 square feet can be made from 64 square feet. Hopefully it's obvious you divide. so 64/15.072 = 4.25
Since we want whole tablecloths and that .25 is a remainder, 4 whole tablecloths can be made.

If i get the correct answer Please!!!!
Answer:
A. 3.2
Step-by-step explanation:
Given
Circumference (c) = 19.8 in
Radius (r) = ?
We know
2πr = c
2 * 3.14 * r = 19.8
6.28 r = 19.8
r = 19.8 / 6.28
r = 3.2 in

Answer:
g has an average rate of change of zero at the intervals [-5,4] and [-2,2]
Step-by-step explanation:
When we talk of the average rate of change, we mean the change in y values divided by the change in x values
Once the change in y-values is zero, then over that interval, the average rate of change is zero
at the point t =- 5, g(t) = 6; at the point t = 4, g(t) = 6
As we can see here, within the interval [-5,4]; the average rate of change is 0
This same pattern is repetitive at points or ranges where we have same values for g(t)
such as;
[-2,2]

Find the area of the figure. (Sides meet at right angles.)
Answer: 37ft^2
Step-by-step explanation:
Create two separate figures. A full square 3x3 and a rectangle 7x4.
The 7ft line on the right minus 3 ft (because we are cutting out that section of the figure) = 4ft
Area of 3x3 square = 3^2 = 9ft^2
Area of 7x4 rectangle = 7x4 = 28ft^2
28+9= 37ft^2
