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.

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.

The missing side of the right angle triangle is 8.0622577483 units.

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.

a. y= 5

b. x=2

c. x= -?

I'm stuck on the last one but I'll tell you how to do it.

For a. I looked at line one and you see that it's on 5? well that is written as y= 5 because there is not x coordinate.

(please people add to this explanation/ answer this question better)

Answer: y= x-2

Step-by-step explanation:

Perpendicularity entails the slope of line a is -1 divided by the slope of line b

m1= (-1/m2)

From y=Mx +c

We compare with x-4y=7

y=(1/4)x-7/4

Meaning m2= 1/4

m1= -1/(1/4)= -1*4= -4

((y-y1)/(x-x1))= ((y2-y1)/(x2-x1))=m1

x1= 2, y1= -4

((y-(-4))/(x-2))= -4

((y+4)/(x-2))= -4

Cross multiply

y+4= -4(x-2)

y= x-2

Adjacent angles must sum to 180 degrees.

x+32=180

x=148 degrees

Answer:

x= 148

Step-by-step explanation:

line CD is a straight angle which means it is 180 degree

to find x you must subtract the known angle from the straight angle

your equation should look like this

Option D is correct,  2x=5 is the equation which matches the hanger diagram.

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.

Step-by-step explanation:

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,

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.

Step-by-step explanation:

for A

[tex]an = a1 + (n - 1)d \\ d = a2 - a1 \\ d = 3 - 1 = 2 \\ an = 1 + (n - 1) \times 2[/tex]

for B

[tex]an = a1 + (n - 1)d \\ d = a2 - a1 \\ d = 9 - 1 = 8 \\ an = 1 + (n - 1) \times 8[/tex]

you can subtract from point 1 to point 2

(9,-2) - (8,3)

9-8= 1

-2-3= -5

therefore horizontal leg is 1

vertical leg is -5

you can also sketch and count the units :)
