Answer 1

Answer:

The correct option are;

On a coordinate plane, a cubic function has an x-intercept of (0, 0)

On a coordinate plane, an oval is in quadrant 1

Step-by-step explanation:

Rotational symmetry of a shape is a shape that when it is rotated on its axis to a given angle less than one complete revolution, the shape looks exactly like the pre-image or original appearance of the shape

For a cubic function that has x-intercept = (0, 0) we have;

y = f(x) = a·x³ + b·x² + c·x

Has the shape f a fan blade and therefore, looks the sane when rotated when rotated through 180°

The shape of an oval looks the same when rotated through 180°

Answer: $1.17 per drink

Step-by-step explanation:

Let x=the cost of one drink

11.5+6x=18.5

subtract 11.5 on both sides

11.5+6x-11.5=18.5-11.5

6x=7

The size of the square cut from each corner will be 1.369 inches. The correct option is C.

What is geometry?

Geometry is one of the oldest branches of mathematics, along with arithmetic. It is concerned with spatial properties such as figure distance, shape, size, and relative position.

Given that a box with no top that has a volume of 1000 cubic inches is to be constructed from a 22 x 30-inch sheet of cardboard by cutting squares of equal size from each corner and folding up the flaps.

The size of the square cut from each corner will be calculated as,

Volume = L x H x W

1000 = 22 x 30 x H

H = ( 1000 ) / ( 660 )

H = 1.538 or 1.369 inches

Therefore, the size will be 1.369 inches.

Answers

Answer:

The area of the new triangle is 180 m²

Step-by-step explanation:

let the height of the triangle = h

let the base of the triangle = b

The area of right triangle is given by;

A =  ¹/₂bh

20 = ¹/₂bh

If we multiple each side of the triangle by 3, the new area of the triangle will be as follows;

A= ¹/₂(3b)(3h)

A = ¹/₂(9) (bh)

A = 9(¹/₂bh)

A = 9(20)

Given:

Temperature at 6 A.M = - 2° F

Temperature increases in 3 hours =  15° F

Find:

Temperature at 9 A.M

at the science school, there is one microscope for every 5 students. The principal figures that in order to have one for every 4 students, she needs 6 additional microscopes. How many students are at the school?

Answers

Answer: 120 students

Explanation:

Let x be the number of scopes
Let a be the number of student at school

1x = 5 students
But 5x = a

1x = 4 students
But the principal needs 6 additional scope so that all the students can use it.

=> (x + 6) = 4 students
=> 4(x + 6) = a

Thus,
5x = 4(x + 6)
5x = 4x + 24
5x - 4x = 24
x = 24

So, there are 24 scopes.

Plug x in both equation and compare:

5x = a
5(24) = a
120 = a

4(x + 6) = a
4(24 + 6) = a
4(30) = a
120 = a

Therefore, the students at the school are 120

-6x+9>7x+74

Answers

Answer:

Step-by-step explanation:

- 6x + 9 > 7x + 74

Treat them as being equal first.

Subtract 9 from both sides.

- 6x + 9 - 9 > 7x + 74 - 9

- 6x > 7x + 65

Subtract 7x from each side

- 6x - 7x > 7x - 7x + 65

- 13x > 65

Divide each side by -13

- 13x / -13  > 65 / -13

x < -5

So x hust be smaller than -5 meaning -6 works but -4 doesn't.

Ankit makes 74% of the free throws he takes in his basketball league. If he is fouled on a three-point shot and gets three free throws, what is the approximate probability he will make all three shots?

Answers

The approximate probability that Ankit will make all three shots is 0.405 or 40.5%.

What is binomial distribution?

A probability distribution known as the binomial distribution is used to characterize the number of successes in a certain number of independent trials, where each trial has only one of two potential outcomes (success or failure) and the chance of success is constant across all trials. For determining the likelihood of achieving a certain number of successes in a set number of trials, it is utilised.

Given, Ankit makes 74% of the free throws.

Using binomial distribution we have:

[tex]P(X=k) = (n C k) * p^k * (1-p)^{(n-k)}[/tex]

For k = 3 we have:

[tex]P(X=3) = (3 C 3) * 0.74^3 * (1-0.74)^{(3-3)}\\\\P(X=3) = 0.74^3[/tex]

P(X=3) ≈ 0.405

Hence, the approximate probability that Ankit will make all three shots is 0.405 or 40.5%.

First we get rid of the exponent 2 by muliplying the (1/2) two times.

(1/2)×(1/2) = 1/4

Now we have:

1/4 - 6(2 - 2/3)

Now we solve the equation in the other paraenthesis:
