Help please<3 for all questions with solutions plz
Answer:
a) [tex]h = -\frac{7}{4}[/tex], b) [tex]h = f\,\circ\,g (-5) = \frac{3}{2}[/tex], c) [tex]h = g\,\circ\,f (-2) = \frac{3}{8}[/tex]
Step-by-step explanation:
We proceed to solve each exercise below:
a) [tex]f(-2) +3\cdot g(0)[/tex]
[tex]h = \frac{2\cdot (-2)}{3\cdot (-2)+5}+3\cdot \left(\frac{3}{0+4} \right)[/tex]
[tex]h = \frac{-4}{-6+5} +3\cdot \left(\frac{3}{4} \right)[/tex]
[tex]h = -4+\frac{9}{4}[/tex]
[tex]h = \frac{-16+9}{4}[/tex]
[tex]h = -\frac{7}{4}[/tex]
b) [tex]h = f\,\circ \,g (-5)[/tex]
[tex]h = f\,\circ\,g (x) = \frac{\frac{6}{x+4} }{\frac{9}{x+4}+5 }[/tex]
[tex]h = f\,\circ\,g (x)= \frac{\frac{6}{x+4} }{\frac{9+5\cdot (x+4)}{x+4} }[/tex]
[tex]h = f\,\circ\,g (x) = \frac{6}{29+5\cdot x}[/tex]
[tex]h = f\,\circ\,g (-5) = \frac{6}{29+5\cdot (-5)}[/tex]
[tex]h = f\,\circ\,g (-5) = \frac{3}{2}[/tex]
c) [tex]h = g\,\circ\,f(-2)[/tex]
[tex]h = g\,\circ \, f (x) = \frac{3}{\frac{2\cdot x}{3\cdot x + 5} + 4 }[/tex]
[tex]h = g\,\circ\,f (x) = \frac{3}{\frac{2\cdot x +4\cdot (3\cdot x +5)}{3\cdot x +5 } }[/tex]
[tex]h = g\,\circ \,f (x) = \frac{3\cdot (3\cdot x +5)}{2\cdot x +12\cdot x +20}[/tex]
[tex]h = g\,\circ\,f(x) = \frac{9\cdot x +15}{14\cdot x +20}[/tex]
[tex]h = g\,\circ\,f(-2) = \frac{9\cdot (-2)+15}{14\cdot (-2)+20}[/tex]
[tex]h = g\,\circ\,f (-2) = \frac{-3}{-8}[/tex]
[tex]h = g\,\circ\,f (-2) = \frac{3}{8}[/tex]

Find the probability of rolling divisors of 24
Answer:
5/6 is the probability
Step-by-step explanation:
Factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24 and rolling a 6-sided die you can get 1, 2, 3, 4, 5, 6 so 5 is the only thing you can roll that isn't a factor of 24 so
A number cube is rolled one time. Determine the probability of not rolling a 1
or a 6.
Answer:
the probability of NOT rolling a 1 or a 6 is a 4/6 or 2/3 chance

which of the following methods can’t
be used to find the zeros of a Function?
• Substitute x=0 in the function and Solue
for f(x).
• Factor the Function and apply the zero-product
property to its factors.
• Apply the quadratic formula.
• Graph the function using a table of values.
Imagine a researcher posed a null hypothesis that in a certain community, the average energy expenditure should be 2,100 calories per day. He randomly sampled 100 people in that community. After he computed the t value by calculating a two-tailed t-statistic, he found that the probability value was 0.10. Thus, he concluded:
Answer: I fail to reject the Null Hypothesis H₀ and conclude that average energy expenditure is 2100 calories per day.
Step-by-step explanation:
Null Hypothesis H₀ : average energy expenditure is 2100 calories per day
Alt Hypothesis H₁: average energy expenditure is NOT 2100 calories per day
now since
P-value (0.10) > ∝ (0.05),
then he should say;
i fail to reject the Null Hypothesis H₀ and conclude that average energy expenditure is 2100 calories per day.
4 cups water for every 1/2 cup soap. How much water would be needed if I have 2/3 cup soap
Answer:
8 cups of water
Step-by-step explanation:
You will need 8 cups of water because if you look closely then notice that 1 + 1 = 2 and 2 + 1 = 3 so 2/8 is 8 cups of water.
State what additional information is required in order to know that the triangles are congruent for the for the reason given
Answer/Step-by-step explanation:
1. Only one side and an included angle is known. To prove that both triangles are congruent by the SAS Congruence Theorem, an additional information such as a corresponding second side (KJ, and HJ) must be given to be equal to each other.
KJ = HJ
2. Additional information such as a second corresponding angle (angles C and W must be known to prove both triangles are congruent by SAS.
<C = <W
3. Additional information needed is a second corresponding angles must be known to prove the AAS.
4. Additional information needed is the corresponding angles, R and L, which should be equal to prove the ASA.
<R = L
5. Additional information needed: <C = <H
6. Additional information needed: equal hypotenuse lengths of both traingles.

4.8 + 2.2w − 1.4w + 2.4 ?
Answer:
7.2+0.8W
Step-by-step explanation:
Answer:
0.8w + 7.2
Step-by-step explanation:
Separate the numbers with and without variables.
4.8 + 2.4 = 7.2
2.2w - 1.4w = 0.8w
( Remember when u put ur answer together the number with variables should be in front of the number without variables! or whatever i dont remember lol i only remember how to solve. )

a fisherman floats 58ft. out from the shore. he notices a bird in the sky directly above the shoreline. if the angle of elevation from the fisherman to the bird is 23 degrees, how far is the fisherman from the bird.
Answer:
63 ft
Step-by-step explanation:
We solve this question using Trigonometric function of Cosine
cos θ = Adjacent/Hypotenuse
From the question:
θ = 23°
Adjacent = The distance of the fisherman from shore = 58 ft
Hypotenuse = The distance of the fisherman from the bird = x ft
Hence:
Cos 23 = 58/x
Cross Multiply
Cos 23 × x = 58
x = 58/Cos 23
x = 63.00890189 ft
Approximately = 63 ft
The distance of the fisherman from the bird is 63 ft
What is the unit rate for meters per second if a car travels 450 meters in 25 seconds?
Answer:
18m/s
Step-by-step explanation:
Formula = 450 meters in 25 seconds
Average speed = 450m/25s
The unit rate is equivalent to 18m/s.
[Basically, just divide 450 meters by 25 seconds to get 18 meters per second. 18 is the unit rate :) ]

At a high school the student government is made up of 5 seniors, 4 juniors, 3 sophomores and 2 freshmen. If there are 8 seniors, 9 juniors, 12 sophomores and 7 freshmen running, in how many ways can the student government be selected?
Answer:
32598720Step-by-step explanation:
Combination for the school government requires:
5 out of 8 seniors = 8! / 3!5! = 6*7*8/2*3 = 7*8 = 564 out of 9 juniors = 9! / 4!5! = 6*7*8*9/2*3*4= 7*2*9 = 1263 out of 12 sophomores = 12! / 3!9! = 10*11*12/2*3 = 10*11*2 = 2202 out of 7 fishermen = 7! / 2!5! = 6*7/2 = 21So number of total ways is:
