Answer:

C

Step-by-step explanation:

because The graph of which quadratic function has roots of 7 and 3 and passes through (2, 10), so therefore its C

The equation f(x) = 2x² -20x +42 and the function has minimum at x=5 which is f(5) = -8 option (C) is correct.

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex]  Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

Part A)

The quadratic function has roots of 7 and 3

f(x) = (x - 7)(x - 3)

f(x) = x² -3x -7x +21

f(x) = x² -10x +21

Multiply by:

f(x) = 2x² -20x +42

Plug (2, 10)

10 = 8 - 40 +42 = 10

Part B) From the graph, the function has minimum at x = 5

f(5) = -8

Thus, the equation f(x) = 2x² -20x +42 and the function has minimum at x=5 which is f(5) = -8

#SPJ2

Answer:

1/2

Step-by-step explanation:

The Rational Root Theorem says that any rational root has

1. a numerator that is a factor of the constant term

2. a denominator that is a factor of the leading coefficient (that's attached to the highest-power term)

Numerator:  [tex]\pm 1[/tex]

Denominator: [tex]\pm 2[/tex]

That means there are only two possible rational roots: [tex]\pm \frac{1}{2}[/tex]

Try them both by plugging them into the polynomial.

[tex]2\left(\frac{1}{2}\right)^3 + 3\left(\frac{1}{2}\right)^2 -1= \frac{1}{4}+\frac{3}{4}-1 =0[/tex]

Aha!  The negative one-half value does not produce 0

Answer:

The distance between the two points is [tex]\sqrt 53[/tex]

Step-by-step explanation:

First you find the distance between the x values which is 2 units and then you find the distance between the two y values which is 7 units. Then you use the pythagorean theorem to find the distance between the two points. Since the distance between the x values is 2 and the distance between the y values is 7 then you do 2²+7² and you get the square root of 53 since the pythagorean theorem equation is a²+b²=c².

Add up all the numbers

Answer:

first blank is 90/100

second blank is 145/100

Step-by-step explanation:

Answer:

x = 18

Step-by-step explanation:

We can say that:

(2x + 13) + 90 + 41 = 180

2x + 144 = 180

2x = 36

x = 18

Hope this helps!

Answer:

Step-by-step explanation:

Problem 1

g(-23) = 3

g(0) = 5

2 = g(10)

1 = g(34)

Problem 2

No, because g(x) = f(-x).  For g(x) to inverse of f(x), g(f(x)) = x

Problem 3

tan(50) = 1.19

Height of statue = 250*1.19 - 150

= 147.9 ft

Problem 4

cosθ = 9/12

θ = 41.41 deg.

Answer:

Step-by-step explanation:

g(x) is inverse of f(x)

so g(f(x))=x

g(-23)=3

g(0)=5

g(10)=2

g((34)=1

no, it is an inverse

4 inverse fn, g(r(x))=x

but here g(x)=r(-x)

so g(r(x))=r(-r(x)) n NOT =x

pedestal + statue = 250*tan(50degree) = 297.94

statue ht = 297.94-150 = 147.94 ft

cos(theta) = 9/12

theta = 41.41 deg.

Answer:

Total amount Omar earn = $120

Step-by-step explanation:

Given:

Total amount Omar, Hala and Lujain got paid = $240

Ratio of money Omar, Hala and Lujain got paid = 5:9:10

Find:

Total amount Omar earn

Computation:

Total amount Omar earn = [Total amount Omar, Hala and Lujain got paid][Omar'ratio / Total ratio]

Total amount Omar earn = [240][5 / (5+9+10)]

Total amount Omar earn = [240][5 / (24)]

Total amount Omar earn = [24][5]

Total amount Omar earn = $120

Answer:

36

Step-by-step explanation:

Work out the terms inside the parenthesis from x = 2 to x = 5. Hint: there will be 4 terms.

x = 2 ---> 0

x = 3 ---> 1

x = 4 ---> 2

x = 5 ---> 3

The sigma symbol means that you have to add them all up so the sum is 6. Therefore,

(6)^2 = 36

Answer:

36

Step-by-step explanation:

Sum the terms (x - 2) for x = 2 to 5 then square the result

[ (2 - 2) + (3 - 2) + (4 - 2) + (5 - 2) ]²

= ( 0 + 1 + 2 + 3 )²

= (6)²

= 36
