You decide to invest $250 in an account that yields a return of approximately 4% each year. If you were to write an exponential equation representing the situation, what would the initial value be?
Answer:
250x.04=x
Step-by-step explanation:
250x.04 would be 10 so you get a 10 doller return each year.
You decide to invest $250 in an account that yields a return of approximately 4% each year. Then, the initial value would be 10 doller return each year.
What are exponential functions?When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function.
There usual form is specified below. They are written in several such equivalent forms.
For example, [tex]y^{x}[/tex], where a is a constant is an exponential function.
You decide to invest $250 in an account that yields a return of approximately 4% each year.
If you were to write an exponential equation representing the situation,
= 250 x 0.04
= 10
Then, the initial value would be 10 doller return each year.

Answer:
1) D and F, their side lengths are proportional and same degree corners
2) E and F
3) yes, their side lengths are proportional and same degree corners
Step-by-step explanation:
In a statistics activity, students are asked to determine if there is a difference in the proportion of times that a spinning penny will land with tails up, and the proportion of times a spinning dime will land tails up. The students are instructed to spin the penny and the dime 30 times and record the number of times they land tails up. For one student, the penny lands tails side up 18 times, and the dime lands tails side up 20 times.
Based on the 98% confidence interval, (–0.36, 0.22), is there evidence of a difference in proportions of tails side up for a penny and a dime?
There is convincing evidence because the two sample proportions are different.
There is not convincing evidence because the interval contains 0.
There is not convincing evidence because the interval contains both negative and positive values for the true difference.
Answer: B) There is not convincing evidence because the interval contains 0.
==============================================================
Explanation:
The 98% confidence interval (-0.36, 0.22) means we are 98% confident that the difference of proportions p1-p2 is somewhere between those two endpoints of -0.36 and 0.22 Values in this interval are possible values of p1-p2.
Note how 0 is in this interval. So it's possible that p1 - p2 = 0. Because of this, we fail to reject the null hypothesis. The null in this case is that p1 - p2 = 0 which can be restated as p1 = p2. The null is the assumption that the two population proportions (p1 and p2) are the same.
The alternative hypothesis is that p1-p2 is not zero. If we got a confidence interval like (0.22, 0.55), this example doesn't have 0 in the interval, then that would mean we reject the null since its unlikely that p1-p2 is equal to zero.
----------------
In short,
If the confidence interval contains 0, then you fail to reject the nullIf the confidence interval doesn't contain 0, then you reject the null.In this case, we fail to reject the null and we don't have enough evidence to show that p1 = p2 is false. So for now, we assume it's true.
Which equation matches the hanger diagram?
pls help !!!
Option D is correct, 2x=5 is the equation which matches the hanger diagram.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
We need to find the equation which matches the hanger diagram.
Hanger models are a visual representation of an equation
For the hanger to remain balanced, each side has to have the same weight. Like a seesaw, a scale, or a barbell.
In the left side of hanger there 2 x's and on right side there are fives ones.
So 2x=5 is the equation which satisfies the given hanger diagram.
Hence, Option D is correct, 2x=5 is the equation which matches the hanger diagram.

Answer:
1) x = 12.2
3) x = 21.7
5) x = 17.9
7) x = 31.8
Step-by-step explanation:
Use Pythagorean Theorem (a^2 + b^2 = c^2 where a and b are bases and c is hypotenuse)
1) 10^2 + 7^2 = x^2
100 + 49 = x^2
149 = x^2
x = sqrt 149 which is about 12.2
3) 16^2 + x^2 = 27^2
256 + x^2 = 729
x^2 = 473
x = sqrt 473 which is about 21.7
5) 9^2 + x^2 = 20^2
(we know the other base is 9 because in an isosceles triangle, the altitude (the height) is the same as the median (which divides the base into half)
81 + x^2 = 400
x = sqrt 319 which is about 17.9
7) 16^2 + y^2 = 22^2 (y is the height of the triangle)
256 + y^2 = 484
x = sqrt 228
(sqrt 228)^2 + (44-16)^2 = x^2
228 + 784 = x^2
x^2 = sqrt 1012 which is about 31.8
The function f(x) = x2 - 6x + 9 is shifted 5 units to the right to create g(x).
What is g(x)?
A. g(x) = (x + 5)2 - 6(x + 5) +9
B. g(x) = (x2 - 6x + 9) + 5
C. g(x) = (x2 - 6x + 9) - 5
D. g(x) = (x - 5)2 - 6(x - 5) + 9
Answer:
D. g(x)=(x-5)^2 -6(x-5)+9

4x-8+3x-16+95=180 or else im so confused
Answer:
x = 17, see below for angle measures
Step-by-step explanation:
You're on the right track!
The sum of those two angles inside the triangle equal that opposite angle outside of the triangle. Therefore, you can set them equal to each other.
(4x - 8) + (3x - 16) = 95
Because you are adding the expressions, you can take away the parentheses without changing anything.
4x - 8 + 3x - 16 = 95
Now you want to combine like terms on the left side.
4x + 3x - 8 - 16 = 95
7x - 24 = 95
Combine like terms once again.
7x = 119
Divide to isolate x.
x = 119/7
x = 17
Plug this value back into each expression to find the angle measures.
∠HFG = 4x - 8
∠HFG = = 4(17) - 86
∠HFG = 68 - 8
∠HFG = 60º
∠FGH = 3x - 16
∠FGH = 3(17) - 16
∠FGH = 51 - 16
∠FGH = 35º
∠FHI = 95ª
∠FHG = 180 - 95
∠FHG = 85º

The missing side of the right angle triangle is 8.0622577483 units.
What is Pythagoras theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
Triangle is a right angle triangle.
And the sides of a right-angled triangle are:
Base = 4 unit
Perpendicular = 7 units.
To find the length of the hypotenuse:
We apply Pythagoras theorem,
(hypotenuse)² = (base)² + (perpendicular)²
Substituting the values in the equation,
(hypotenuse)² = (4)² + (7)²
(x)² = 16 + 49
(x) = √(65)
(x) = 8.0622577483
Therefore, the value of x is 8.0622577483 units.
