-Chetan K
Answer: f/2 = -5
Step-by-step explanation:
Given
f/2 + 9 = 4
Subtract 9 on both sides
f/2 + 9 - 9 = 4 - 9
f/2 = -5
Multiply 2 on both sides
f/2 × 2 = -5 × 2
f = -10

Answer:
Correct choice is option A. 6a + 8b ≤ 200
7a + 5b ≤ 150
---> cereal A with grams will be multiplied by the sodium available in one gram of cereal A
----> The solution from the above equation would then be added to the cereal B with grams as well as its sodium content per grams.
6a + 8b ≤ 200
---> Cereal A's grams × Cereal A's calories + Cereal B's grams × Cereal B's calories is ≤ 150
so, 7a + 5b ≤ 150
What is the sum of 5 numbers whose average is 5 more than 5?
Answer:
The sum of 5 numbers with an average of 5 more than 5 is 50
Step-by-step explanation:
Let the first five letters of the alphabet be equal to the 5 numbers being summed.
Let the average be represented by the following equation:
[tex]\frac{a + b + c + d + e}{5} = 10[/tex]
To find the sum, we should get rid of the denominator. To do that we multiply 5 on both sides
[tex]\frac{a + b + c + d + e}{5} (5) = 10(5)\\a + b + c + d + e = 50[/tex]
Therefore, we see to it that the sum of the 5 numbers is 50.
express x²+4x-2 in the form of (x+a)²+b
Answer:
(x+2)^2-6
Step-by-step explanation:
(x+2)^2 = x^2 + 4x + 4
x^2 + 4x + 4 -6 = x²+4x-2
Answer:
(x + 2)² - 6
Step-by-step explanation:
Using the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² + 4x
x² + 2(2)x + 4 - 4 - 2
= (x + 2)² - 6

An insurance company sells a homeowner's insurance policy that is $600 per year per policy. The insurance company predicts that the probability of having a home being damaged in the area it sells this policy is about 11,000. If the home is damaged, the insurance company expects to pay $400,000 to the homeowner. If the company were to sell 250 policies, how much money can it expect to gain or lose
Answer:
profit of $140,910
there is a missing number I will assume that the probability is 1 in 11,000
company expected revenue per policy = $600
companies expected expense = 400,000 * (1/11,000) = -36.36
profit per policy = $536.64
$536.64*250 = $140,910

Find the vertex of the graph of the function.
f(x) = (x - 10)2 - 8 (2 points)
A. (10, -8)
B. (-8, 0)
C. (0, 10)
D. (-8, 10)
Answer:
A. (10, -8)Step-by-step explanation:
Given function:
f(x) = (x - 10)² - 8The vertex form of a quadratic function:
f(x) = (x - h)² + k, where (h, k) is the vertexAccording to the above, the vertex of the given function is:
(10, -8)Correct choice is A
Step-by-step explanation:
y=(x-10)²-8General equation of parabola
vertex form is given by
y=a(x-h)²+kOn comparing we get
h=10k=-8So vertex is at (10,-8)

Differentiate
[tex] \frac{ {x}^{3} + 2x ^{2} }{x} [/tex]
with respect to their variable.
Answer:
2x + 2
Step-by-step explanation:
Given
[tex]\frac{x^3+2x^2}{x}[/tex] ( divide each term on the numerator by x )
= x² + 2x
Differentiate each term using the power rule
[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex] , then
[tex]\frac{d}{dx}[/tex] (x² + 2x ) = 2x + 2
Are points N, R, S, and W coplanar? Explain.
Two or more points are said to be coplanar if they all lie on the same plane.
Based on the given diagram, we can see that the points N, R, S, and W all lies on the same plane A. Due to this fact, we can conclude that N, R, S, and W are coplanar.
Assuming any of the four points fall outside plane A, then we can say they are not coplanar.
Based on the explanation above, we can conclude that points N, R, S, and W all lie on the same plane.
