Answer:

We have the coordinates of vertex T after the translation as (-5,0)

Step-by-step explanation:

Firstly, we get the coordinates of vertex T

we have this as;

(-2,-2)

Translating to the left means we are going to subtract the specific units from the x-coordinate

2 units up means we are going to add to the y-coordinate value

So, we have it that;

(-2-3, -2+ 2) = (-5,0)

Answer:

84%

Step-by-step explanation:

Given that :

Number that prefers digital copy = 4

Number who prefers hard copy = 21

Total number of samples =

(digital + hard copy) = 25

Percentage who prefers hard copy :

(Number who prefer hard copy / total number of samples) * 100%

(21 / 25) * 100%

0.84 * 100%

= 84 %

Answer:

In total, the amount of milk every kid combined drank is 672 ounces.

Step-by-step explanation:

If four kids drank 24 ounces of milk for seven days, you would solve it as follows:

First, the amount all the kids drink in one day combined is 96 ounces.

If they drink 96 per day, and they do so for a week (7 days), then that is 96 × 7 because its 96 seven times.

7 × 96 = 672

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug the given points (80,20) and (120,30) into the equation

[tex]\frac{y_2-y_1}{x_2-x_1}\\= \frac{30-20}{120-80}\\= \frac{10}{40}\\= \frac{1}{4}[/tex]

Therefore, the slope of the line that passes through these points is [tex]\frac{1}{4}[/tex].

Answer:

The value of g[f(2)] = 13

Step-by-step explanation:

Given functions:

f(x) = x²

g(x) = 3x + 1

Find:

The value of g[f(2)]

Computation:

f(x) = x²

By putting x = 2 in f(x)

f(x) = x²

f(2) = 2²

f(2) = 2 × 2

f(2) = 4

So the value of f(2) = 4

Value of  f(2) putting in g(x)

g(x) = 3x + 1

g(x) = 3x + 1

g[f(2)] = 3[f(2)] + 1

We know that f(2) = 4

So,

g[f(2)] = 3[f(2)] + 1

g[f(2)] = 3[4] + 1

g[f(2)] = 12 + 1

g[f(2)] = 13

The value of g[f(2)] = 13

Step-by-step explanation:

mass= kg

v=m/s

k =kg×(m/s)²

k unit =kg×m²/s²

Step-by-step explanation:

a) 6-9b=3a

First:Subtract

3b=3a

Second: Devide

3b/3a

=(3÷3)(b÷a)

=1b/a

= b/a

B) 6b+2a=3a

First:Transpose (Group the like terms. signs will change.)

-3a+2a=-6b

=-1a=-6b

Second:Divide

=-1a/-6b:(-1÷-6)(a÷b)

=1a/6b

=a/6b

C)a/3=b+2

First: Transpose

a=3+2+b

=a/6+b

Answer:

[tex]A' = (-4,4)[/tex]

Step-by-step explanation:

Given

[tex]A = (-2,2)[/tex]    [tex]B = (1,3)[/tex]       [tex]C = (1,0)[/tex]

[tex]k =2[/tex] --- scale factor

Required

Determine A'

This is calculated as:

[tex]A' = A * k[/tex]

[tex]A' = (-2,2) * 2[/tex]

[tex]A' = (-2 * 2,2 * 2)[/tex]

[tex]A' = (-4,4)[/tex]

Answer:

The answer is "99.82% and 86.99%".

Step-by-step explanation:

In point a:

[tex]=P(X < 45)\\\\= P(Z < \frac{45-29.09}{5.46}) \\\\=P(Z < 2.9139)\\\\=0.9982\\\\=99.82\%[/tex]

In point b:

[tex]=P(X >17)\\\\= P(Z > \frac{17-22.37}{4.77}) \\\\=P(Z > -1.1258)\\\\=0.8699\\\\=86.99\% \\\\[/tex]

Answer:

100 Candy Bars

Step-by-step explanation:

Hey!

==================================================================

Ayden wants to sell a total of $150 worth of candy bars for his school fundraiser. Each candy bar costs $1.50. How many candy bars will he have to sell in order to meet his goal?

--------------------------------------------------------------------------------------------------------------

We can create an algebraic Equation to solve this.

- We know that Each Candy Bar costs $1.50.

-We multiply the Amount of Candy Bars with the price.

-We know the profit should be $150

⇒ 1.50x = 150

-Divide by 1.50 on both sides

⇒ 1.50x/1.50 = 150/1.50

-Simplify

⇒ x = 100

==================================================================

Hope I Helped, Feel free to ask any questions to clarify :)

Have a great day!

       -Aadi x

Answer:

Step-by-step explanation:

Answer:

The error are

1) The use of the angle addition postulate, for [tex]m \widehat{ACD}[/tex]

2) The assumption that [tex]m \widehat{BC}[/tex] = 90°

The vertical angle property between  [tex]m \widehat{CD}[/tex] and [tex]m \widehat{FA}[/tex] should be used to find 'x'

x = 5

Step-by-step explanation:

From the drawing of the circle, we are given;

AD = A diameter of the circle

∴ [tex]m \widehat{ACD}[/tex] = 180°

By angle addition postulate, we have;

[tex]m \widehat{ACD}[/tex] = [tex]m \widehat{AB}[/tex] + [tex]m \widehat{BC}[/tex] + [tex]m \widehat{CD}[/tex]

By substitution property of equality, we have;

180° = [tex]m \widehat{AB}[/tex] + [tex]m \widehat{BC}[/tex] + [tex]m \widehat{CD}[/tex]

[tex]m \widehat{AB}[/tex] = 5·x°

[tex]m \widehat{BC}[/tex] = Not given

[tex]m \widehat{CD}[/tex] = 15·x°

However;

[tex]m \widehat{CD}[/tex] is the vertically opposite angle to [tex]m \widehat{FA}[/tex]

∴  [tex]m \widehat{CD}[/tex] = [tex]m \widehat{FA}[/tex] = (16·x - 5)°

[tex]m \widehat{CD}[/tex] = 15·x° = (16·x - 5)°

15·x° = (16·x - 5)°

∴ 5 = 16·x° - 15·x° = x

x = 5

[tex]m \widehat{BC}[/tex] = 180° - ([tex]m \widehat{AB}[/tex] + [tex]m \widehat{CD}[/tex]) = 180° - (15·x° + 5·x°) = 180° - (20·x°)

[tex]m \widehat{BC}[/tex] = 180 - (20×5)° = 80°

[tex]m \widehat{BC}[/tex]  = 80°

The error are the use of the angle addition postulate, for [tex]m \widehat{ACD}[/tex], and the assumption that [tex]m \widehat{BC}[/tex] = 90° rather than the vertical angle property between  [tex]m \widehat{CD}[/tex] and [tex]m \widehat{FA}[/tex] in trying to find 'x', from which x = 5.
