The given quadratic function has two real zeros.

We are given a function. The function is quadratic in nature.  We need to check whether the given quadratic function has one, two, or no real solutions. We will use the quadratic formula to determine the answer. The equation of the quadratic function is given below.

f(x) = 4x² + 5x - 29

The general form of a quadratic equation is ax² + bx + c. The values of the variables a, b, and c for the given equation are 4, 5, and -29, respectively. The quadratic formula is given below.

x = (-b ± √D)/2a

The variable "D" represents the discriminant of the quadratic equation. If the value of D is less than zero, then no real roots exist. If the value of D is equal to zero, then only one real root exists. If the value of D is greater than zero, then two real roots exist. The formula for discriminant is D = b² - 4*a*c. We will calculate the discriminant for the given equation.

D = b² - 4*a*c

D = 5² - 4*(4)*(-29)

D = 25 + 464 = 489

The value of the discriminant is positive, so the function has two real roots.

The equation of circle that have diameter of 12 cm is x2+(y-3)2=36

What is equation of circle?

The standard equation of a circle is given by:

(x-h)2 + (y-k)2 = r2

Where (h, k) is the coordinates of center of the circle and r is the radius.

Given, diameter = 12 cm

radius = 6 cm

Hence, center is on y-axis hence, x = 0

the point we get (h,k) =(0,3)

D: Associative property you move the parentheses to different numbers.

Option (B) is the correct one and -3x - 6 < -33 and -3x - 6 ≥ −36 is an equivalent form of the given compound inequality

Given, a compound inequality

−33 > (−3x − 6) ≥ −36

Now, we can interpret the given inequality separately also,

−33 > (−3x − 6)

On simplifying, we get

-33 > -3x - 6

-33 + 6 > -3x

-27 > -3x or -3x - 6 < -33

also, (−3x − 6) ≥ −36

On simplifying, we get

-3x - 6 ≥ −36

-3x ≥ −36 + 6

-3x ≥ −30 or -3x - 6 ≥ −36

So, -3x - 6 < -33 and -3x - 6 ≥ −36 is an equivalent form of the given compound inequality.

Hence, Option (B) is the correct one and -3x - 6 < -33 and -3x - 6 ≥ −36 is an equivalent form of the given compound inequality.

Answer:

12.573%

Step-by-step explanation:

Percent means "parts per 100".

Therefore, to convert a decimal to a percent, multiply the decimal by 100.

When multiplying a decimal by a multiple of 10, simply move the decimal point to the right the same number of places as there are zeros.

Therefore, to multiply a decimal by 100, simply move the decimal point 2 places to the right.

⇒ 0.12573 × 100 = 12.573%

Answer:

rental cost of each movie is $2.5

rental cost of each video game is $5.5

Step-by-step explanation:

use x for movie and y for video game. Then you get the equations
2x+12y=71 and 5x+3y=29

then you solve each equation for either x or y.
when you solve for y you will get
y = (71 -2x) / 12    and y = (29 -5x) / 3

because y is the same, you put those equations together
(71-2x) / 12 = (29 -5x) / 3
then solve for x and you get x = 2.5

then you put 2.5 for x in either of the original equations and solve for y.
for both equations you will get y = 5.5

The rate of change(slope) of the graph is 7 / 5.

The rate of change function is defined as the rate at which one quantity is changing with respect to another quantity.

The slope(rate of change) is change in the dependent variable with respect to the change in the independent variable.

The slope is rise over run.

Therefore, let's find the slope of the graph as follows:

slope = y₂ - y₁ / x₂ - x₁

Therefore, using (0, -7) and (5, 0)

slope = 0 - (-7) / 5 - 0

slope = 7 / 5

The value of x for the given triangle is 12.

According to the question,

We have the following information:

We have a figure of two triangles joined together and some of the angles are marked.

Now, we observe the figure carefully then the base of both triangles are parallel to each other.

Now, 45° will be the angle of triangle on right hand side because they are vertically opposite angles.

We know that the sum of three angles of triangle is 180°.

For the RHS triangle, let's take third angle to be y:

45+65+y=180

110+y =180

y =180-110

y = 70°

Now, y will be equal to (6x-2) because they are vertically opposite angles.

6x-2 = 70

6x = 70+2

6x = 72

x = 72/6

x = 12

Hence, the value of x for the triangle is 12.

Number of customer you usually assist = 52 customers per day

This week to hit your goal you have to assist more customers

Number of more customer you need assist = 9 customers per day

So, Total customer you'll assist per day to hit goal = 52 + 9

Given that, Su's Sushi is $2 more than Darbi sushi and the cost of Su's sushi is represented by s.

Let the price of Darbi's sushi is $x.

Then, the price of Su's sushi is
s = x + 2

x = s -2

The total cost is:

  x + s

Since they divided the total cost evenly, the cost each paid is:

(2s-2)/2

= s -1

Now, the cost after paying a 20% tip is:

(s - 1) + 20% of (s - 1)
