Answer:

They are all right

Step-by-step explanation:

Answer:

well, each right angle is divided into 90 equal parts where each part & it's called degrees

each degree is then divided into 60 equal parts where each part is called a minute

each minute is divided again into 60 equal parts where each part is called a second.

Answer:

We conclude that option A is true as x = 1 is the root of the polynomial.

Step-by-step explanation:

Given the polynomial

[tex]f\left(x\right)\:=\:x^2\:+\:2x^2\:-\:x-2[/tex]

Let us determine the root of the polynomial shown below.

[tex]\:0=\:x^2\:+\:2x^2\:-\:x-2[/tex]

[tex]0=3x^2-x-2[/tex]

switch sides

[tex]3x^2-x-2=0[/tex]

as

[tex]3x^2-x-2=\left(3x+2\right)\left(x-1\right)[/tex]

so the equation becomes

[tex]\left(3x+2\right)\left(x-1\right)=0[/tex]

Using the zero factor principle

[tex]3x+2=0\quad \mathrm{or}\quad \:x-1=0[/tex]

solving

[tex]3x+2=0[/tex]

[tex]3x=-2[/tex]

[tex]\frac{3x}{3}=\frac{-2}{3}[/tex]

[tex]x=-\frac{2}{3}[/tex]

and

[tex]x-1=0[/tex]

[tex]x=1[/tex]

The possible roots of the polynomial will be:

[tex]x=-\frac{2}{3},\:x=1[/tex]

Therefore, from the mentioned options, we conclude that option A is true as x = 1 is the root of the polynomial.

Answer:

9

Step-by-step explanation:

f(x) = 4x- 11

f(5) = 20- 11

f(5) = 9

Answer:

perimeter of triangle IJH= 17.5

Step-by-step explanation:

line IJ is a midsegment, so you can divide the segments FH and GH by 2.

that means segment IH= 4.5 and segment GH=6. segment IJ is given as 7.

add 4.5 + 6 + 7, which equals 17.5

Answer:

\the second and third one

Answer:

-50

Step-by-step explanation:

The average rate of change is synonymous with the slope. Therefore, we will find the slope of the function from x=0 to x=3.

So, we will use the endpoints of the function.

At x=0, f(x)=150. Thus, we have the point (0, 150).

At x=3, f(x)=0. Thus, we have the point (3, 0).

Now, we can use the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (0, 150) be (x₁, y₁) and let (3, 0) be (x₂, y₂). Substitute:

[tex]m=\frac{0-150}{3-0}=-150/3=-50[/tex]

Therefore, the average rate of change for the first three seconds is -50.

Answer:

A: Corresponding

B: Alternate interior

C: Corresponding

D: Alternate exterior

E: Same side interior

Step-by-step explanation:

A: One angle is on the interior and one is on the exterior and they are both on the same side of the transversal which makes them corresponding angles

B: Both are in the interior just on opposite sides of the transversal

C: See answer to A

D: Both are on the exterior and they are on opposite sides of the transversal which makes them alternate exterior

E: Both are on the interior on the same side of the transversal which makes them same side interior.

Answer: x = -10

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

x= -10

Step-by-step explanation:

7x-4(-4x-16)=-166 foil the ()

7x+16x+64= -166  combine terms

23x+64= -166  subtract 64 to both sides

23x= -230  divide by 23

x= -10

Answer:

Step-by-step explanation:

all the sides are different than the other on the bottom of the  shape  the sizes have longer sides and one short at the bottom.

Step-by-step explanation:

Answer:

The width of the garden is 25 feet

The length of the garden is 60 feet

Step-by-step explanation:

The formula for the perimeter of a rectangle

= P = 2L + 2W

Where L = Length, W = Width

The length of the garden is 10 feet more than twice its width.

P = 170

L = 2W + 10

Hence,

170 = 2(2W + 10) + 2W

170 = 4W + 20 + 2W

Collect like terms

170 - 20 = 6W

150 = 6W

W = 150/6

W = 25 feet

The width of the garden is 25 feet

Remember

L = 2W + 10

L = 2(25) + 10

L = 50 + 10

L = 60 feet

The length of the garden is 60 feet

Answer:

Cost of tshirt = £7.29

Cost of what = £0.86

Step-by-step explanation:

2t +3h = 12; 10t + 15h = 60

5t + 4h =33; 10t + 8h = 66

15h -8h = -6

7h = -6; h = -6/7; h = 0.86

2t +3(-6/7) =12

14t -18 = 84

14t = 102; t = 102/ 14; t=7.29
