Answer:

The Answer is 4.79

Step-by-step explanation:

All you have to do Divide 33.53 by 7 then you would get 4.79

I say divide because they want to know how much it one gallon of milk costs So that is why you have to divide

Hope I Helped! :3

Marsha’s scores on seven tests were: 82, 78, 77, 93, 85, 91, and 86. What does she need to score on her next test to have an 86

Naddika [18.5K]

Answer:

The score of her next test is 96

Step-by-step explanation:

<em>If there is a set of data with x terms, then the average is the sum of their values divided by x</em>

<em>Average = sum of values of the x terms ÷ x</em>

We will use this rule to solve the question

∵ Marsha's scores on 7 test were 82, 78, 77, 93, 85, 91, 86

→ Find her total scores on the seven tests

∴ Her total scores = 82 + 78 + 77 + 93 + 85 + 91 + 86 = 592

∴ Her total scores on the 7 tests is 592

∵ Her average score on the 8 test is 86

→ Use the rule of the average to find her total score in the 8 test

∵ 86 = total scores ÷ 8

→ Multiply both sides by 8

∴ 86 × 8 = total scores × 8 ÷ 8

∴ 688 = total scores

∴ Her total scores on the 8 tests is 688

∵ Her total scores on the 7 test = 592

∵ Her total scores on the 8 test = 688

→ The difference between both totals is the score of her next test

∴ The score of her next test = 688 - 592 = 96

∴ The score of her next test is 96

Write functions for each of the following transformations using function notation. Choose a different letter to represent each f

joja [24]

Answer:

1. Translation: g(x) = f(x-a)+b.

2. Reflection around y-axis: h(x) = f(-x)

3. Reflection around x-axis: k(x) = -f(x)

4. Rotation of 90° : $R_{90} (x,y)=(-y,x)$

5. Rotation of 180° : $R_{180} (x,y)=(-x,-y)$ .

6. Rotation of 270° : $R_{180} (x,y)=(y,-x)$ .

Step-by-step explanation:

Let us assume that the transformations namely translation, reflection are applied to a function f(x) and the rotation is applied to the point ( x,y ).

So, according to the options:

We know that 'translation moves the image in horizontal and vertical direction'.

1. As we have to translate the function f(x) 'a' units to the right and 'b' units up. So, the new form of the function becomes g(x) = f(x-a)+b.

Further, we know that 'reflection means to flip the image around a line'.

2. As, we have to reflect the function f(x) around y-axis. The new form of the function is h(x) = f(-x).

3. As, we have to reflect the function f(x) around x-axis. The new form of the function is k(x) = -f(x).

Since, 'rotation turns the image around a point to a certain degree'.

4. As, we have to rotate ( x,y ) counter-clockwise to 90° about the origin, the new form of the function is $R_{90} (x,y)=(-y,x)$ .

5. As, we have to rotate ( x,y ) counter-clockwise to 180° about the origin, the new form of the function is $R_{180} (x,y)=(-x,-y)$ .

6. As, we have to rotate ( x,y ) counter-clockwise to 270° about the origin, the new form of the function is $R_{180} (x,y)=(y,-x)$ .
