Answer:
1/5
Step-by-step explanation:
f(-1) = (-1)^2 = 1
g(f(-1) = g(1)
g(1) = 1/(2(1)+3) = 1/(2+3) = 1/5

12. For angle A it is known that sin(A)>0 and tan (A) <0. If A is drawn in standard position, in which quadrant
does its terminal ray lie?
Answer:
Quadrant 2
Step-by-step explanation:
Sin = opp/hyp and opp is positive in quadrants 1 & 2.
Tan = opp/adj - we need one of these values to be positive and the other negative. adj is negative in quadrants 2 & 3.
Quadrant 2 is found in both of the scenarios that we need to occur.

Each side of a square name tag is 7 centimeters long. What is the name tag's area?
Answer:
49 cm²
Step-by-step explanation:
The area for a square is Area = length x width, and if the square name tag is 7cm long on "each side", that means that both the length and the width are 7cm.
Plug this into the formula to get A = 7cm x 7cm.
This can be simplified to A = 49cm².
Answer: 49 cm^2
Step-by-step explanation:
7 x 7 = 49

a rectangular field has side lengths that measure 9/10 mile and 1/2 mile. What is the area of the field
Answer:
9/20, or 0.45 mile.
Step-by-step explanation:[tex]\\[/tex]
To find the area of a rectangle, multiply length times width. In this problem we are given both the length and width.
[tex]\frac{9}{10}[/tex] × [tex]\frac{1\\}{2}[/tex] is just 9/20, which is 0.45.

Justin played a game with 24 floating plastic ducks each with a colored sticker on the bottom. There are an equal number of red blue and green stickers on the set of ducks. What is the probability that one duck chosen at random will have a red or blue sticker
Answer:
Because there are 24 ducks total and they are separated equally into three categories, we can figure out that there are 24 / 3 = 8 ducks of each color. This makes the probability of pulling a red/blue duck would be (8*2)/24 or 16/24. If we want this to be a percentage we can just solve 16/24*100 and it will give us 66.66...%

A sporting goods company sells a tent with the dimensions shown. The company wants to introduce a new, larger tent that is geometrically similar to the original tent but with a height of 6 feet. How will the volume of the new tent compare with the volume of the original tent?
Answer:
The volume of the new tent will be 27/8 times the volume of the original tent.
Step-by-step explanation:
First, you take the ratio of 6/4 and simplify it down to 3/2.
Next, you take the ratio, and have to get its volume. Volume is just one length CUBED, so you cube both sides.
Then, after you cube the simplified fraction, you get 27/8.

The radius of a sphere is 6 units.
Which expression represents the volume of the sphere, in
cubic units?
27(6)
031(0)3
O 2A(12)2
lo (12)
Answer: 4/3 π 6³
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere: 4/3 π r³
Replacing with the values given:
V = 4/3 π 6³
If we solve the expression:
V = 4.18 (6)^3
V = 904.77 cubic units

In the figure angle a measures 41 degrees and angle d measures 32. What is the measurement of angle E?
Answer:
it is c
Step-by-step explanation:
Find the value of c that makes each trinomial a perfect square.
x² + 3x+c
Answer:
2
Step-by-step explanation:
Plug in 2 for c in the equation:
x² + 3x + 2
x 2
x 1
(x + 2)(x + 1)
Check. Use the FOIL method:
(x)(x) = x²
(x)(1) = x
(2)(x) = 2x
(2)(1) = 2
x² + x + 2x + 2
Combine like terms:
x² + (x + 2x) + 2
x² + (3x) + 2
2 can be a answer for c.

Answer:
The answer is C.
[tex]n = 2t - 1[/tex]
Step-by-step explanation:
You can simply determind the answer by placing all pair of value n and t in the equation, one by one.
First, try the answer A, you should get as following;
[tex]n = t + 2 \\ 1 = 1 + 2[/tex]
and try to see if it is true or not,
in this case,
1 will never equal 1 + 2 (1 ≠ 1 + 2)
Therefore A is not the Answer. Try going through all other choices, and you will find the answer. The calculation is very simple, you probably won't need a calculator!

What is the net change in the temperature relative to when lko woke up
Complete question:
Between the time iko woke up and lunchtime, the temperature rose by 11°. Then by the time he went to bed, the temperature dropped by 14°.
What is the net change in the temperature relative to when lko woke up?
Answer:
The net change in the temperature relative to when lko woke up =
[tex]\bold{-3}[/tex] °
Step-by-step explanation:
Given that between his wake up time and lunch time, temperature rose by 11°. Let the new temperature be [tex] \bold{T1} [/tex] and let the initial temperature(temperature before wakeup time) be [tex] \bold{T} [/tex]
Since the temperature rose by 11°, the new temperature after Iko woke up, T1, would be derived by adding 11° to the initial temperature.
i.e, T1 = T + 11......................(1)
At bed time the temperature dropped by 14°. Therefore, the temperature would now be 14 less than the new temperature T1. It is expressed as:
T1 + (-14).......................... (2)
Let's substitute T + 11 for T1 in equation 2, we have:
T + 11 + (-14)
To find the expression for the net change in temperature, let's subtract the initial temperature T, from (T+11 -14) i.e,
ΔT = (T + 11 - 14) - T
Solving further, we have:
ΔT = T - T + 11 - 14
ΔT = 11 - 14
ΔT = -3°
Therefore, the net change in the temperature relative to when lko woke up is = -3°

Answer:
52
Step-by-step explanation:
This is an isosceles triangle, so the base angles will be the same. Then you know that all of your angles will add up to 180.
Your equation can be:
2(2x+2) + (3x + 1) = 180
x = 25
S = 2(25) + 2
S = 52 degrees
Answer:
52
Step-by-step explanation:
Because SR = TR, ∡S =∡T= 2x+2
For any triangle sum of all angles = 180°.
2x+2 +2x+2+3x+1= 180
7x + 5 =180
x = 25°
∡S =2x+2=2*25+2 = 52°
