Answer:
Step-by-step explanation:
You want to set up a system. We are given some points fo we can set up inputs and outputs. F(0) = 5, given by point (0,5). and F(3)=135, given by point (3,135). The exponential function general equation is F(x)= a(b)^x. plug in out functions into the general equation to get a(b)^0=5 and a(b)^3=135. Then you simplify and solve for a. In the equation a*b^0=5, anything to the power of 0 is 1. so a*1=5. Therefore a=5. we plug in the a to the second equation to find b. 5*b^3=135. b^3=27. b=3 from simplifying. Therefore, the equation should be 5(3)^x. THATS IT!

Answer:
C) 1.25
Step-by-step explanation:
The hypotenuse is the sloping side.
The base is the bottom side.
The triangles are similar, so you can use the sides of either triangle. Let's use the side lengths of the smaller triangle.
Length of hypotenuse: 5
Length of base: 4
Ratio of hypotenuse to base: 5/4
To find a decimal value, divide 5 by 4. Use a calculator or long division.
5/4 = 1.25

Answers
Answer:
81
Step-by-step explanation:
w/9=9
w=9*9
w=81
Answer:
w = 81
Step-by-step explanation:
To get w, you have to do inverse operations. Because w is being divided, we need to multiply to isolate w because multiplication is the opposite of division.
w/9 = 9
(9) (w/9) = (9) (9)
w = 81

Step-by-step explanation:
In an effort to test the hypothesis that the proportion of voters in the younger than 40 year old age bracket who will vote for a particular politician is different than the proportion voters in the above 40 age bracket, the following data was collected. Test hypothesis at 0.10 level of significance.
Population Number Who Will Vote for Politician Sample Size
Below 40 348 700
Above 40 290 650
Required:
a. Reject the Null Hypothesis and condlude that the proportion of voters in the younger than 40 year oid age bracket who will vote for a particular different than the proportion voters in the above 40 age bracket.
b. Do not reject the Null Hypothesis and conclude that the proportion of wotors in the younger than 40 year old age bracket who will vote for a particular politician is not different than the proportion voters in the above 40 age bracket.
Answers
Answer:
We reject H₀ we support the claim that the two proportion are different
Step-by-step explanation:
Younger than 40 years old
Sample size n₁ = 700
x₁ = 348
p₁ = 348 / 700 p₁ = 0,497 p₁ = 49,7 %
Above 40 years old
Sample size n₂ = 650
x₂ = 290
p₂ = 290/ 700 p₂ = 0,414 p₂ = 41,4 %
p = ( n₁*p₁ + n₂*p₂ ) / n₁ + n₂
p = 700 * 0,497 + 650 * 0,414 ) / 700 + 650
p = ( 347.9 + 269,1 ) / 1350
p = 0,457 p = 45,7 %
q = 1 - p q = 54,3 % q = 0,543
CI is 90 % significance level is 10 % α = 10 % α = 0,1 α/2 = 0,05
zscore for α/2 from z- table is : z(c) = 1,64
Test Hypothesis
Null Hypothesis H₀ p₁ = p₂
Alternative Hypothesis Hₐ p₁ ≠ p₂
To calculate z(s) = ( p₁ - p₂ ) / √ pq/n₁ + pq/ n₂
p₁ - p₂ = 0,497 - 0,414 = 0,083
√ pq/n₁ + pq/ n₂ = √ 0,457*0,543/ 700 + 0,457*0,543/ 650
√ pq/n₁ + pq/ n₂ = √ 3,545*10⁻⁴ + 3,82 * 10⁻⁴
√ pq/n₁ + pq/ n₂ = 2,71 * 10⁻² = 0,0271
z(s) = 0,083/ 0,0271
z(s) = 3,06
Comparing z(s) and z(c)
|z(s)| > |z(c)|
Then z(s) is in the rejection region and we reject H₀

Step-by-step explanation:
Here, we need to know the concept of trigonometry
Sine (sin)-- Opposite/Hypotenuse ⇒ O/HCosine (cos)-- Adjacent/Hypotenuse ⇒ A/HTangent (tan)-- Opposite/Adjacent ⇒ O/H---------------------------------------------------------------------------------
Given
θ = 32°
Hypotenuse = 14
x = adjacent side (relative to θ)
Solve
cos ( 32 ) = x / 14
x = 14 cos ( 32 )
x≈11.9

I'll do each of these expression to see which one equals 43.
2⁴ + 3²
16 + 9
25 ≠ 43; So A is out.
5² + 5³
25 + 125
150 ≠ 43; so C is out.
3² + 2³
9 + 8
17 ≠ 43; so D is out.
4² + 3³
16 + 27
43 = 43, so B is the answer to this question.

please someone help me with this ASAP especially with the workout!!
Answers
Answer:
78°
Step-by-step explanation:
From the diagram,
Applying sine rule,
SinA/a = sinC/c................... Equation 1
Given: c = 29 cm, C = 50°, a = 37 cm
Substitute into equation 1 and solve for A.
sinA/37 = sin50°/29
sinA = (37×sin50°)/29
sinA = (37×0.766)/29
sinA = 28.34/29
sinA = 0.9774
A = sin⁻¹(0.9774)
A = 77.8°
A ≈ 78°
Hence the measure of angle A = 78°
