Suppose you want to transform the graph of the function y=tan(x+pi/4)-1 into the graph of the function y=-tan(x+pi/2)+1 which tr

ansformations should you perform.
A) Reflect the graph of the first function across the x-axis, translate it pi/4 units to the left, and translate it 2 units up.
B) Reflect the graph of the first function across the x-axis, translate it pi/4 units to the right, and translate it 2 units up.
C) Reflect the graph of the first function across the line y = -1, translate it pi/4 units to the left, and translate it 2 units up.
D) Reflect the graph of the first function across the line y = -1, translate it pi/4 units to the right, and translate it 2 units up.

Answer:

A) Reflect the graph of the first function across the x-axis, translate it pi/4 units to the left, and translate it 2 units up

Step-by-step explanation:

We are given

parent function as

y=tan(x+\frac{\pi}{4})-1

and new function as

y=-tan(x+\frac{\pi}{2})+1

We can also write as new function as

y=-tan(x+\frac{\pi}{4}+\frac{\pi}{4})+1+1-1

y=-tan(x+\frac{\pi}{4}+\frac{\pi}{4})-1+2

We can see that

x-value is added by pi/4

So, it is shifted left side pi/4

and y-value is added by 2 units

so, it moves 2 units upward

we can see that

y-value is multiplied by -1

so, it reflected about x-axis

so,

A) Reflect the graph of the first function across the x-axis, translate it pi/4 units to the left, and translate it 2 units up

Answer:

See Explanation

Step-by-step explanation:

Given

\triangle ABC = \triangle DE F

Required

Which would not prove the similarity

\triangle ABC = \triangle DE F  implies that:

The following angles are congruent

\angle A = \angle D

\angle B =\angle E

\angle C =\angle F

And the following lengths are congruent

AB = DE

BC =EF

CA = FD

The options are not clear; so, it's a bit difficult to select the correct option.

<em>Any of the options that is different from the above list of 6 congruent pairs is the answer to your question.</em>

Maria and laurie are making orange juice.Maria use 2 cups of concentrate and 5 cups of water. Laurie uses 3 cups of concentrate
Phantasy [73]

Answer:

Step-by-step explanation:

To obtain the strongest mix :

Maria:

2 cups of concentrate ; 5 cups of water

Ratio = 2/5 = 0.4 concentrate per 1 cup of water

Laurie:

3 cups of concentrate ; 7 cups of water

Ratio = 3/7 = 0.4285714 concentrate per 1 cup of water

0.4285714 > 0.4

Hence, Laurie's mix is the strongest as it has higher concentrate per cup of water.
