Answer:

30

Step-by-step explanation:

Since there are 900 today, and the variants square each day, we can take the square root of 900.

[tex]\sqrt{900} =30[/tex]

900 = q^2, so q = 30, so yesterday there were 30 variants

Answer:

-3/4

Step-by-step explanation:

The slope of line passes through the points (-9,10) and (-13,13)​ is -3/4.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

(-9,10) and (-13,13)​

So, slope= (13 - 10)/ ( -13 + 9)

slope= 3 / (-4)

slope= -3/4

Hence, the slope of line is -3/4.

Answer:

comic books = 2

magazines = 15

Step-by-step explanation:

Let c = number of comic books bought

Let m = number of magazines bought

He bought 17 items, so

c + m = 17

Comic books cost $4 each and magazines cost $3 each.

He spent $53 on comic books and magazines, so

4c + 3m = 53

Rearrange c + m = 17 to make m the subject:

m = 17 - c

Substitute  m = 17 - c  into  4c + 3m = 53  and solve for c:

4c + 3(17 - c) = 53

⇒ 4c + 51 - 3c = 53

⇒ c = 2

Substitute c = 2  into m = 17 - c to and solve for m:

m = 17 - 2 = 15

The initial height of the ball is the y-intercept of the function

The initial height she threw the ball from is 35

The function is given as:

[tex]h(x) = -16x^2 + 3x +35[/tex]

Set x = 0.

So, we have:

[tex]h(0) = -16 * 0^2 + 3*0 +35[/tex]

Evaluate the exponent

[tex]h(0) = -16 * 0 + 3 * 0 + 35[/tex]

Evaluate the products

[tex]h(0) = 0 + 0 + 35[/tex]

Evaluate the sum

[tex]h(0)= 35[/tex]

It's 360 feet (The person above)

Answer:

360 ft squared

Step-by-step explanation:

you have 3 (2 shapes but one is done twice)

2 rectangles and a larger rectangle

the 2 rectangles

3 is the width, and 15 is the length

15*3 = 45 * 2 (for the other one)

and you get 90ft squared

then you have the larger rectangle. it is 15 feet wide and 18 in length (15+3)

15*18 = 270

270 ft squared + 90 ft squared = 360 ft squared

Step-by-step explanation:

Area = base x height

⇒ A = 10.25 x 7 = 71.75 = 71 3/4 ft²

Answer:

71 3/4 ft²

Step-by-step explanation:

the area is the product of the base (10 1/4) and height (7)

10.25 x 7 = 71 3/4 ft²

Product of two polynomials can be done by distribution of multiplication over addition. The product of  [tex]-2x(x^2 - 3)[/tex] is [tex]-2x^3 + 6x[/tex]

Suppose a, b and c are three numbers. Then we have:

[tex]a(b + c) = a\times b + a\times c[/tex]

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

The product result of the given expression is

[tex]-2x(x^2 - 3) = -2x^{1 + 2} + 6x = -2x^3 + 6x[/tex]

It is because when bases are same and there is multiplication, then powers add up, so we have: [tex]a^b \times a^c = a^{b+c}[/tex]

Thus,

The product of  [tex]-2x(x^2 - 3)[/tex] is [tex]-2x^3 + 6x[/tex]

Step-by-step explanation:

the point-slope form in general is

y - y1 = m(x - x1)

where (x1, y1) are the coordinates of a point, and m is the slope.

so, we have

y - -1 = 4/3 × (x - 3)

or simplified

y + 1 = 4/3 × (x - 3)

Answer:

[tex]y + 1 =\frac{4}{3} (x-3)[/tex]

Step-by-step explanation:

We are given that a line contains the point (3, -1), and has a slope of [tex]\frac{4}{3}[/tex].

We want to write the equation of this line in point-slope form.

Point-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1 ,y_1)[/tex] is a point.

Since we are already given the slope and the point of the line, we can plug these values into the formula to get the equation.

Let's start with the slope; replace m with [tex]\frac{4}{3}[/tex] in the formula.

[tex]y-y_1=\frac{4}{3}(x-x_1)[/tex]

Now, replace 3 as [tex]x_1[/tex] and -1 as [tex]y_1[/tex]. Remember that the formula has subtraction in it.

[tex]y--1=\frac{4}{3} (x-3)[/tex]

This can be simplified to become:

[tex]y + 1 =\frac{4}{3} (x-3)[/tex]
