Answer 1

Answer:

These two  lines that are running horizontally are parallel lines.

The angle  with measure 115 degrees is  congruent to angle 2 (by the law of parallel lines).

So, if these two angles are congruent, angle 2 is also 115 degrees.

what is the effect on the graph of the function f(x)=x^2 when f(x) is changed to f(x)+9

Answers

Given:

The function is

[tex]f(x)=x^2[/tex]

This function is changed to f(x)+9.

To find:

The effect on the graph of the function.

Solution:

The translation is defined as

[tex]g(x)=f(x)+b[/tex]                .... (1)

Where, b is vertical shift.   If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

The new function is

[tex]g(x)=f(x)+9[/tex]           ...(2)

From (1) and (2), we get

[tex]b=9[/tex]

So, the graph of f(x) shifts 9 units up as shown in the below graph.

On one island there lived two friends, Ana and Banana. One of them always tells the truth, while the other always lies. When asked which one is the liar among them, they said: Ana: "Banana ate ten apples yesterday, and he is telling the truth." Banana: "No, I ate five apples yesterday, and Ana is lying." How many apples did Banana eat yesterday?

Answers

Answer:

Number of apples ate = 5

Step-by-step explanation:

Fact:

One of them always tells the truth, while the other always lies.

To find how many apples banana ate, we have to figure out who is lying between Ana and Banana.

Ana: "Banana ate ten apples yesterday, and he is telling the truth."

If Ana is telling the truth, that means Banana is also telling the truth because of the statement (... and he is telling the truth).

This is not possible as one of them must be lying. The only option left is that Ana is lying.

Since Ana is lying, it means banana is telling the truth.

Banana: "No, I ate five apples yesterday, and Ana is lying."

Number of apples ate = 5

Find the slope of the line that passes through the pair of points (6,-2) and (5,-4).
Show all work necessary and write your final answer in the box.

Answers

Answer:

slope = -10/7

Step-by-step explanation:

co-ordinates = (6,-2) (5,-4)

slope = (y² - y¹) / (x² - x¹)

slope = (-4 - 6) / (5 - (-2))

slope = (-10) / (5+2)

slope = (-10) / 7

slope = -10 / 7

A zoo has an equal number of African elephants and Asian elephants. The African elephants cost £11 per day to feed and the Asian elephants cost £9 per day to feed. The total daily bill for feeding all of the zoo's elephants is £1000. How many elephants does the zoo have?

Answers

Answer:

The zoo has 50 African elephants and 50 Asian elephants which means that there are 100 elephants.

Step-by-step explanation:

From the information provided, you can say that the result of adding up the African elephants cost to feed per day for the number of African elephants plus the Asian elephants cost to feed per day for the number of Asian elephants would be equal to £1000, which can be expressed as:

11x+9y=1000, where:

x is the number of African elephants

y is the number of Asian elephants

Now, as the statement indicates that the zoo has an equal number of African elephants and Asian elephants, this means that x=y and you can replace y with x and solve for x:

11x+9x=1000

20x=1000

x=1000/20

x=50

According to this and considering that the zoo has an equal number of African elephants and Asian elephants, the answer is that the zoo has 50 African elephants and 50 Asian elephants which means that there are 100 elephants.

In one simulation, they are asked to change the initial concentrations of several gases, one at a time, to see the impact on ATP production in a muscle cell.If the students begin by removing oxygen from the muscle cell, what should they predict will occur?The cell will produce more ATP because oxygen inhibits ATP production in the mitochondria.The cell will produce no ATP at all since oxygen is critical to ATP production.The cell will produce the same amount of ATP since oxygen is not a factor in ATP production.The cell will produce some ATP but in much lower amounts than if oxygen was present.
