Antonio uses a calculator to find 38 minus StartFraction 44 minus 16 over 4 EndFraction and gets a result of –10. Which statement best describes his work? Antonio is correct. Antonio found the answer for 38 minus 44 minus sixteen-fourths. Antonio found the answer for StartFraction 38 minus 44 minus 16 over 4 EndFraction. Antonio found the answer for 38 plus StartFraction 44 minus 16 over 4 EndFraction.

Measure of ∠6 = (3x + 7)°

Measure of ∠7 = 76°

∠6 and ∠7 are vertically opposite angles, so their measures will be equal.

Which means :

[tex] = 3x + 7 = 76[/tex]

[tex] = 3x = 76 - 7[/tex]

[tex] = 3x = 69[/tex]

[tex] = x = \frac{69}{3} [/tex]

[tex]\color{hotpink} = x = 23[/tex]

Let us now place 23 in the place of x and see if it forms 76 :

[tex] = 3x + 7 = 76[/tex]

[tex] = 3 \times 23 + 7 = 76[/tex]

[tex] = 69 + 7 = 76[/tex]

[tex] = 76 = 76[/tex]

Thus, the value of x we found is correct.

Therefore, the value of x = 23

Given:

The graph passes through the given points (4,-2) and (2,0).

To find:

The quadratic function [tex]y=a(x-h)^2[/tex].

Solution:

We have, quadratic function

[tex]y=a(x-h)^2[/tex]            ...(i)

The graph passes through the given points (4,-2) and (2,0). It means the equation must be true for these points.

Putting x=4 and y=-2 in (i), we get

[tex]-2=a(4-h)^2[/tex]         ...(ii)

Putting x=2 and y=0 in (i), we get

[tex]0=a(2-h)^2[/tex]          ...(iii)

Divide (iii) by (ii).

[tex]\dfrac{0}{-2}=\dfrac{a(2-h)^2}{a(4-h)^2}[/tex]

[tex]0=\dfrac{(2-h)^2}{(4-h)^2}[/tex]

[tex]0=(2-h)^2[/tex]

[tex]0=2-h[/tex]

[tex]h=2[/tex]

Putting h=2 in (ii), we get

[tex]-2=a(4-2)^2[/tex]

[tex]-2=a(2)^2[/tex]

[tex]-2=a(4)[/tex]

Divide both sides by 4.

[tex]\dfrac{-2}{4}=a[/tex]

[tex]\dfrac{-1}{2}=a[/tex]

Putting [tex]a=-\dfrac{1}{2}[/tex] and h=2 in (i), we get

[tex]y=-\dfrac{1}{2}(x-2)^2[/tex]

Therefore, the required quadratic function is [tex]y=-\dfrac{1}{2}(x-2)^2[/tex].

Answer:

The actual area of land is 80 mi² .

Step-by-step explanation:

Given that we have to find the actual area so first we have to square the ratio(scale factor) :

1 in : 5 mi

(1 in)² : (5 mi)²

1 in² : 25 mi²

Next, the actual area will be :

1 in² = 25 mi²

(1 × 3.2) in² = (25 × 3.2) mi²

3.2 in² = 80 mi²

The actual area of the section of land if A map using a scale inch of 1 to 5 miles shows a section of land with an area of 3.2 in.² is 80 miles².

An area is a unit of measurement used to describe the size of a region on a planar or curved surface. While a plane region or area refers to the area of a shape or planar lamina, a surface region or plane area refers to the area of an open surface or the boundary of a three-dimensional object.

Given:

A map using a scale inch of 1 to 5 miles, land with an area of 3.2 in.²

Calculate the scale factor as shown below,

1 inch: 5 miles

(1 inch)² : (5 miles)²

1 inches² : 25 miles²

Calculate the actual area as shown below,

Actual area = 25 × 3.2

Actual area = 80 miles²

Answer:

Option A

Step-by-step explanation:

Original equation of the parabola,

f(x) = x²

Step 1.

Function 'f' is vertically stretched by a scale factor of 4,

Image function will be,

g(x) = 4x²

Step 2.

Followed by the translation by 3 units to the right and 1 unit down,

h(x) = g(x - 3) + 1

h(x) = 4(x - 3)² + 1

Therefore, Option A will be the correct option.

Answer:

Final cost = £779

Step-by-step explanation:

It is given that:

Cost of summer holiday =  £650

Amount increased by 11%

Increased cost = 11% of 650

Increased cost = [tex]\frac{11}{100}*650[/tex]

Increased cost = 0.11 * 650 =  £71.50

Amount after increment = 650 + 71.50 = £721.50

Further increase = 8%

Amount = 0.08 * 721.50 = £57.72

Final cost = 721.50 + 57.72 =  £779.22

Thus,

Final cost = £779

Answer:

B. x2-3x+1

Step-by-step explanation:

The  solution to the division problem is x² -3x + 1.

The correct option is (B).

An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.

Given:

x³ + x² - 11x + 4/x + 4

Now, perform the division we get

                  (x+ 4) | x³ + x² - 11x + 4 | x² -3x + 1

                             x³ + 4x²

                     -______________

                                   -3x² - 11x

                                   -3x² - 12x

                     -______________

                                              x  + 4

                                              x  + 4

                            -______________

                                              0

Hence, the solution is x² -3x + 1.

Answer:

The most expensive she can buy is the soccerball

Step-by-step explanation:

Given

[tex]Total =\$29.00[/tex]

[tex]T\ Shirt = \$15.32[/tex]

[tex]Soccer\ Ball= \$12.87[/tex]

[tex]Baseball\ Cap = \$8.39[/tex]

[tex]Shin\ Guards = \$14.98[/tex]

[tex]Water\ Bottle = \$5.93[/tex]

Required

Using [tex]\$15.32 + c = \$29.00[/tex], what is the most expensive she can buy?

[tex]\$15.32 + c = \$29.00[/tex]

Subtract $15.32 from both sides

[tex]\$15.32 - \$15.32 + c = \$29.00 - \$15.32[/tex]

[tex]\$15.32 - \$15.32 + c = \$13.68[/tex]

[tex]c = \$13.68[/tex]

This means that she can not afford items that cost more than $13.68

i.e. the shin guards which costs $14.98

The items she can afford and their prices are:

[tex]Soccer\ Ball= \$12.87[/tex]

[tex]Baseball\ Cap = \$8.39[/tex]

[tex]Water\ Bottle = \$5.93[/tex]

The most expensive of them all is:

[tex]Soccer\ Ball= \$12.87[/tex]
