Answer:

m∠1 = 90°

m∠2 = 53°

m∠3 = 37°

Step-by-step explanation:

The given diagram shows three straight lines intersecting at one point.

According to the Vertical Angles Theorem, when two straight lines intersect, the opposite vertical angles are congruent.

Angle 1 is vertically opposite to the angle marked 90°. Therefore:

m∠1 = 90°

Angle 2 is vertically opposite to the angle marked 53°. Therefore:

m∠2 = 53°

Angle 3 is vertically opposite to the angle marked 37°. Therefore:

m∠3 = 37°

Given the Function:f(x) = -2e^x find f(x), if x=3
So far what I manage to grasp with this equation is
replacing the "x" with 3 So: f(3)= -2e^(3)
The answer ( using the scientific calculator) gave me -6
I have no Idea what are the other steps to this equation.

Answers

f(x)=-2e^x
x=3
f(3)=-2e^3
pemdas so exponents first
e^3
e=2.718281828454590
cube that
20.0855

now we have
-2 times 20.0855=-40.1711

answer should be -40.1711
(I see what you did wrong, if -6=-2 times e^3, divide -2, 3=e^3, maybe you just put -2 times 3 by mistake)

okay e^3 is 20.08553692 x -2 = 4.017107385
maybe you had your calculator on the wrong mode or entered it wrong

The square root of 16 is 4.
4 times 3 is 12.
-54 times 3 is -162.
12 times -162 is -1944.

A ski club with 28 members went on a ski trip. some members rented skis and the rest rented snowboards. if skis rent for $16.00 a day and snowboards rent for $19.00 a day, and the club spent 478.00 in rentals, how many ski club members rented skis?

Answers

$there \ are \ 28 \ members \n the \ number \ of \ members \ renting \ skis - x\nthe \ number \ of \ members \ renting \ snowboards - y\nskis \ rent \ for \ \$16.00 \ a \ day \ and \ snowboards \ rent \ for \ \$19.00 \ a \ day\n\n\begin{cases} x+y=28 \ \ / \cdot (-16) \n 16x+19y = 478 \end{cases}$

Answer:

16 skis and 18 snowboards were rented.

Step-by-step explanation:

Let the number of skis rented be and the number of snowboards rented be .

If a total of people rented on a certain day, then the total number of skis and snowboards rented that particular day is also .

This gives us the equation

If skis cost $ , then number of skis cost $ .

If snowboards cost $ , then number of snowboards cost $ .

The total cost will give us another equation,

From equation (1),

We put equation (3) into equation (2) to get,

We expand the brackets to obtain,

We group like terms to get,

This implies that,

We divide both sides by to get,

We put into equation (3) to get,

Therefore skis and snowboards were rented.
