A basketball player has already scored 56 points in a game. The team record for points in a game is 72. Which equation would allow you to find out how many more points the player needs to tie the record?a. 72 + x = 56
b. 56 − 72 = x
c. 56 + x = 72
d. 56 + 72 = x

Answers

C. 56 + x =72 because the team player already scored 56 points you would need to add an unknown amount of points in this case x to find out how many points you need in order to reach 72 points and if you are curious how many points you need in order to get to 72 you need 16 points.

Answer:

C. 56 + x =72

Answer:

24 cars

Step-by-step explanation:

By using 11 cars and AED 79.75, you can find out the cost of washing 1 car.

(AED 79.75)/(11 cars) = AED 7.25 / car

Now we divide AED 174 by AED 7.25/car to find the number of cars.

(AED 174) / [(AED 7.25)/car] = (174/7.25) cars = 24 cars

Answer: 24 cars

Solve 3x2 + x + 10 = 0. Round solutions to the nearest hundredth.

Answers

$3 x^(2) + x + 10 = 0$
$x = \frac{-b(+or-) \sqrt{ b^(2) - 4ac } }{2a}$
$x = \frac{-1(+or-) \sqrt{ 1^(2) - 4(3)(10) } }{2(3)}$
: . x = \frac{-1 + \sqrt{-119} }{6} OR $x = (-1 - √(-119) )/(6)$

Thus the roots or the solutions to this equation are imaginary because the discriminant $√(-119)$ is negative and a negative number is undefined when rooted.

The graph of the function f(x) = (x + 2)(x − 4) is shown.Which describes all of the values for which the graph is negative and increasing?

all real values of x where x < −2
all real values of x where −2 < x < 4
all real values of x where 1 < x < 4
all real values of x where x < 0

Answers

The function is negative below the zeros which would be from -2 to 4.
It would be increasing from the vertex to the zero,4.
So the answer would be 1 < x < 4

The values for which the graph is negative and increasing are all real values of x where 1 < x < 4.

Given

The graph of function;

$\rm f(x) = (x + 2)(x - 4)$

What is a graph?

A graph goes from being negative to positive (or the other way around) by passing through the x-axis. in other words when f(x) = 0.

Then,

$\rm f(x) = (x + 2)(x - 4)=0\n\nx+2 =0\ x=-2\n\nx-4=0\ x=4$

For increasing and decreasing for anything other than a quadratic and linear function you need calculus.

The function is negative below the zeros which would be from -2 to 4.

It would be increasing from the vertex to zero,4.

Hence, the values for which the graph is negative and increasing are all real values of x where 1 < x < 4.

Given:

The net value of the bakery (in thousands of dollars) t months after its creation is modeled by

$v(t)=2t^2-12t-14$

Paul wants to know what his bakery's lowest net value will be.

To find:

The function in a different form (factored or vertex) where the answer appears as a number in the equation.

Solution:

Factor form is used to find the x-intercepts and vertex form is used to find the extreme values (maximum or minimum). So, here we need to find the vertex form.

We have,

$v(t)=2t^2-12t-14$

$v(t)=2(t^2-6t)-14$

Adding and subtract square of half of 6 in the parenthesis, we get

$v(t)=2(t^2-6t+3^2-3^2)-14$

$v(t)=2(t^2-6t+3^2)+2(-9)-14$

$v(t)=2(t-3)^2-18-14$ $[\because (a-b)^2=a^2-2ab+b^2]$

$v(t)=2(t-3)^2-32$

Vertex form:

$f(x)=a(x-h)^2+k$

where, (h,k) is vertex.

On comparing this equation with vertex form, we get the of the function is (3,-32).

Therefore, the vertex form is $v(t)=2(t-3)^2-32$ and the function has minimum value at (3,-32). It means, minimum net value of the bakery is -32 after 3 months.

The vertex form is v(t) = 2(t - 3)² - 32 and the function has a minimum value at (3,-32). It means the minimum net value of the bakery is -32 after 3 months.

Given that,

Paul opened a bakery.

The net value of the bakery (in thousands of dollars) t months after its creation is modelled by the equation v(t) = 2t²- 12t - 14.

Paul wants to determine the bakery's lowest net value.

To rewrite the function in a different form,

Find the vertex of the quadratic equation.

The vertex form of a quadratic equation is given by,

v(t) = a(t-h)² + k,

Where (h, k) represents the coordinates of the vertex.

Proceed, v(t) = 2t² - 12t - 14,

v(t) = 2(t² - 6t) - 14,

v(t) = 2(t² - 6t + 3² - 3²) - 14

v(t) = 2(t - 3)² - 32

Vertex form:

v(t) = a(t-h)² + k,

where, (h,k) is vertex.

On comparing this equation with vertex form, we get the function is (3,-32).

Therefore,

The vertex form is v(t) = 2(t - 3)² - 32 and the function has a minimum value at (3,-32). It means minimum net value of the bakery is -32 after 3 months.
