Answer:
Step-by-step explanation:
Let's use "completing the square" to solve this quadratic: x^2 − 18x + 58 = 0
We want to rewrite the terms "x^2 - 18x" in the form '(x - h)^2 - h^2 and leave the terms '58 = 0' as they are:
Taking half of the coefficient of x (which coefficient is -18), we get -9. We square this -9, obtaining 81, and then rewrite
"x^2 - 18x" as "x^2 - 18x" + 81 - 81." To this we must append '58 = 0":
x^2 - 18x + 81 - 81 + 58, or x^2 - 18x + 81 - 23 = 0
Now the first three terms condense to the expression
(x - 9)^2, which is then followed by "-23":
(x - 9)^2 = 23
Solve this for x. Taking the square root of both sides, we get
x - 9 = ± √23
so that one root is x = 9 + √23
and the other is x = 9 - √23

A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y).
The results of the regression were:
y=ax+b
a=-1.154
b=39.771
r2=0.386884
r=-0.622
Use this to predict the number of situps a person who watches 8 hours of TV can do (to one decimal place)

The graphs below have the same shape. What is the equation of the blue graph?
Answer:
D. [tex]g(x)=(x+4)^{2}-3[/tex]
Step-by-step explanation:
g(x) is a translated function. Compared to the parent function, f(x)=[tex]x^{2}[/tex], it has been shifted 4 left and 3 down. The rule for quadratic functions is [tex]y=a(x-h)^{2} +k[/tex], where h is the x-translation (horizontal) and k is the y-translation (vertical). In g(x) h=-4 and k=-3. While it might seem like h is positive, remember that since in rule it is being subtracted it must be negative.

Step-by-step explanation:
suppose you fill the cone with water and empty the water into the cylinder. how many times will you empty the water from the cone into the cylinder.
A. 3 TIMES B. 6 TIMES C.9 TIMES
=========================================================
Explanation:
Recall that from a previous screenshot you posted, that
[tex]\text{Volume of Cone} = \frac{1}{3}*\left(\text{Volume of Cylinder}\right)[/tex]
If we multiply both sides by 3 and swap both sides, then we end up with
[tex]\text{Volume of Cylinder} = 3*\left(\text{Volume of Cone}\right)[/tex]
So that's why we need 3 cups of water, if each cup is the cone in the diagram. Keep in mind that the height of the cylinder and the cone must be same. The two radius values must be the same as well. You don't need to have r = h be true.

spend $7.50 a day on
lunch. How many
lunches will I be able to
buy before I run out of
money?
Answer:
13 lunches
Step-by-step explanation:
100 divided by 7.5 = 13 1/3
since you have to buy whole lunches, and since we're talking about money, we need to round down to get 13.
Harsha thinks of a number. She subtracts 2 then multiplies the result by 3. The answer is the
same as subtracting 6 from the number then multiplying by 7. What number did Harsha
think of?
Answer:
-42.
Because you subtract to the 2. -2, multiply by 3, -6. Then multiplying by 7. And getting -42.

The population of Virginia is 30% less than the population of Georgia. If
the population of Georgia is 10.5 million, what is the population of
Virginia?
7,150,000
The population of Georgia is 10,500,000.
The population of Virginia is 30% less than that.
So the population of Virginia is 10,500,000 - 30% which equals 7,150,000

Soil sells for 8 1/4 cents per pound. how much would you save if you bought a 100 pound sack for $7.45?
The amount saved is $0.80 or 80 cents.
Since Soil sells for 8 1/4 cents per pound, the coat for 100 pound sack will be:
= 8 1/4cents × 100
= 8.25 cents × 100
= 825 cents
Since 100 cents = $1
825 cents = 825/100
825 cents = $8.25
Since the 100 pound sack was bought for $7.45, the amount saved will be:
= $8.25 - $7.45
= $0.80
