Answer:
f(x) = -(x+3)(x-4)
f(x) = -[tex]x^{2}[/tex]+x+12
Step-by-step explanation:
The equation of the parabola is y = -(x + 3) (x - 4).
What is parabola?In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.
Given that a graph of a parabola, we need to find the equation of the parabola,
Intercept form equation of the parabola:
y = a(x - p) (x - q), x-intercepts are (-3, 0) and (4, 0).
x = -3 ------ x + 3 = 0
x = 4 ------- x - 4 = 0
y = a(x + 3) (x - 4)
It passes through (0, 12). Substitute (x, y) = (0, 12)
12 = a(0+3)(0-4)
12 = -12a
a = -1
Intercept form equation of the parabola:
y = -(x + 3) (x - 4)
Hence, the equation of the parabola is y = -(x + 3) (x - 4).

The function f(t) = |98.6-x|, represents a persons's variance from normal body temperature, where x represents a person's current body temperature in degrees Fahrenheit. Medical professionals say healthy individuals should have a variance of no more than 0.5 degrees Fahrenheit.
Answers
Answer:
98.1°F ≤ x ≤ 99.1°F
Step-by-step explanation:
Given the function:
f(x) = |98.6 - x|
Variance = 0.5
98.6°F - x = ± 0.5
Lower bound :
98.6 - 0.5 ≤ x
98.1 ≤ x
Upper bound :
x ≤ 98.6 + 0.5
x ≤ 99.1
Hence,
98.1°F ≤ x ≤ 99.1°F

The perimeter of a worksheet is 48 inches. The worksheet is 14 inches long. How tall is it?
inches
Answers
Answer: 10 inches
Step-by-step explanation:
1. multiply 14 by 2 to get 28.
2. Subtract 28 from 48 to get 20
3. Divide 20 by 2 to get 10
your answer is 10
Answer: 10 inches
Step-by-step explanation:
a worksheet is usually a rectangle
the formula for the perimeter of a rectangle is 2x + 2y
Lets say that x = the length and y = the height
it already gives you x = 14, so plug everything in to find y
P = 2x + 2y
48 = 2(14) + 2y
48 = 28 + 2y plug in x = 14 and multiply
20 = 2y subtract 28 from both sides to get this
y = 10 then divide both sides by 2 to get the answer

I need help plzzzzzzz
Answers
Answer:
6
Step-by-step explanation:
180-80=100
100-10=90
90 divided by 15=6
they’re supplementary angles (they add up to 180°), so we need to set up an equation by adding them to equal 180°:
15x + 10 + 80 = 180
combine like terms
15x +90 = 180
subtract 90 from move sides
15x = 90
divide both sides by 15
x= 6

A restaurant manager states the number of customers that enter the restaurant is equal to 4
times the number of people that buy a hotdog from the hotdog cart plus 11. The manager also
states that the number of customers that enter their restaurant is equal to 1 times the number of
people that buy a hotdog from the hotdog cart plus 38. What number of people buying a hotdog
from the hotdog cart across the street makes the equation 4x + 11 = 1x + 38 true? Round
your answer to the nearest whole number.
Answers
Answer:
9
Step-by-step explanation:
No of customers that enter the restaurant is equal to 4 times the number of people that buy a hotdog from the hotdog cart plus 11.
The number of customers that enter their restaurant is equal to 1 times the number of people that buy a hotdog from the hotdog cart plus 38.
The equation that shows the given condition,
4x + 11 = 1x + 38
x is the no of people
Taking the like terms,
4x-1x=38-11
3x=27
x = 9
So, there are 9 people buying a hotdog from the hotdog cart.

Max and his brother exercise together. Max does half as many sit-ups as his brother does during a workout. If Max's brother does between 100 and 150 sit-ups, which expression describes s, the number of sit-ups that Max does?
A. 0 ≤ s ≤ 50
B. 50 ≤ s≤ 75
C. 100 ≤ s ≤ 150
D. 200 ≤ s ≤ 300
Answers
Answer:C is the correct answer,
Step-by-step explanation:
50 ≤ s≤ 75 describes the number of sit-ups that Max does so option (B) will be correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Max does "s" number of sit-ups then max brother will do "2s".
Now,
Given that,
Max's brother does between 100 and 150 sit-ups
So,
100 ≤ 2s ≤ 150
Divide by 2 into both sides
50 ≤ s ≤ 75
Hence " 50 ≤ s≤ 75 describes the number of sit-ups that Max does".

At the grocery store, Jerry spent $24.75 for 3 pounds of chicken and 3 pounds of cheese. The cheese cost $4.50 per pound. What was the cost of the chicken
per pound?
Answers
Answer:
$3.75 per pound of chicken
Step-by-step explanation:
Price of 3 pounds of cheese $ 4.50x3= $13.50
$24.75-$13.50 = $11.25 (price of 3 pounds of chicken)
Chicken : $11.25/ 3 = $3.75 per pound
$11.25 + $13.50 = $24.75

Using function concepts, it is found that the correct option is given by:
D. The function is negative when x<0
How the sign of a function is determined?If the graph is above the x-axis, it is positive.If the graph is below the x-axis, it is negative.In this problem, the graph of the function is the red line, and:
For values of x < 0, the function is below the x-axis, hence it is negative.For values of x > 0, the function is above the x-axis, hence it is positive.Thus, option D is correct.
