Answer:

x=21.8

Step-by-step explanation:

The angles are complementary, and add to 90 degrees. We know this because of the little square in the corner.

x+68.2=90

Solve for x by isolating it. To do this , subtract 68.2 from both sides

x+68.2-68.2=90-68.2

x=21.8

Answer:

21.8

Step-by-step explanation:

basically what you're looking at is a right angle (the square) which is 90 degrees and part of it is 68.2 and the other is x.

This can be written as the equation 68.2 + x = 90.

Subtract 68.2 from both sides to get x = 21.8;

and there you go! That's your answer! Hope that helped a little bit :)

A function f is given by the formula f(x)=a⋅ekx for constants a and k. we also know that f(4)=12 and f(7)=5. find numerical valu

masha68 [24]

The given function is

$f(x) = a e^{kx}$

And it is given that $f(4)=12$

On using this information, we will get

$12 = a e^{4k}$

And the other point is $f(7)=5$

Using this point, we will get

$5= ae^{7k}$

Dividing both equations, we will get

$\frac{12}{5} = e^{4k-7k}$

Taking ln to both sides

$ln( \frac{12}{5} ) = -3k$

$k = -0.29$

Performing back substitution ,

$12 = a e^{-0.29*4}
\\
a =38.28$

Y=-4x unit rate/constant/slope 8TH GRADE

Solnce55 [7]

9514 1404 393

Answer:

-4

Step-by-step explanation:

In a linear equation, the terms "unit rate", "rate of change", "constant of proportionality", and "slope" all refer to the coefficient of x (the independent variable).

Here, the coefficient of x is -4.

The slope is -4.

_____

Additional comment

Strictly speaking the "constant of proportionality" only refers to the x-coefficient (k) when the equation is of the form ...

y = kx . . . . . with no added constant

"Slope", "unit rate", and so on, can also refer to the x-coefficient (m) when the equation has a non-zero y-intercept (b):

y = mx + b

Does 10p/2q = 5p/q I think it is not equal but it doesn't seem right.

Rufina [12.5K]

Answer: $\frac{10p}{2q}=\frac{5p}{q}$ (TRUE)

Step-by-step explanation:

For this exercise it is important to remember that, by definition, fractions have the following form:

$\frac{a}{b}$

Where "a" is the numerator and "b" is the denominator.

The numerator and the denominator are Integers, but the denominator cannot be zero ( $b\neq 0$ )

In this case you have the following equation provided in the exercise:

$\frac{10p}{2q}=\frac{5p}{q}$

To find out if the left side of the equation is equal to the right side, it is necessary to simplify the fraction on the left.

Notice that the numerator and the denominator of the fraction on the left can be both divided by 2. Then, you can simplify it.

So, you get;

$\frac{5p}{q}=\frac{5p}{q}\ (TRUE)$
