Answer:
Z/X
Step-by-step explanation:
cause sin is p/h and p=Z and h=X
[tex] \displaystyle \large \tt{ \sin a = \frac{opposite}{hypotenuse} }[/tex]
First, we have to focus on ∠a, at the angle a or ∠a, the opposite is z because ∠a is the opposite side of z.
The hypotenuse side is always x, even if we change from ∠a to ∠b (b = 90°-a)
So what we have now are:
opposite = z (Refer to the bold text)hypotenuse = x (hypotenuse is always the side that is opposed to a right angle.)Substitute the letter in the ratio:
[tex] \displaystyle \large \boxed{ \sin a = \frac{z}{x} }[/tex]

» [tex]❎ \: \: f(2) = 1[/tex]
f(2) is 5/2
» [tex]{ \boxed{✔}} \: f(4) = \frac{7}{2} [/tex]
Answer:
B. f(0) = 3/2 and E f(4) = 7/2Step-by-step explanation:
Given function:
f(x) = 1/2x + 3/2Find the following:
f(-1/2) = 1/2(-1/2) + 3/2 = -1/4 + 6/4 = 5/4, incorrectf(0) = 3/2, given in the table, correctf(1) = 2, given in the table, incorrectf(2) = 5/2, given in the table, incorrectf(4) = 1/2(4) + 3/2 = 2 + 3/2 = 7/2, correctCorrect choices:
f(0) = 3/2f(4) = 7/2If your gross monthly income will be $3,750, you need to determine the net pay for your monthly budget.

Which equation is equivalent to the given equation? x^2 - 10x = 14
Answer:
(x - 5)² = 39
Step-by-step explanation:
Given
x² - 10x = 14
To obtain an equivalent equation use the method of completing the square.
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = 14 + 25
(x - 5)² = 39
I believe that the answer you are looking for is (x-5)²-39, if you use the completing the square method.
Solution:
x²-10x=14
Transferring 14 from the right side to the left side,
x²-10-14=0
Squaring the equation,
(x-5)²-39, or (x-5)²=39 (Depends on how you prefer to write it).
So, that is the final answer. I hope this helped. If you have any questions about the answer, please let me know. Enjoy your day and take care!
I need some help on 9 and 10
Answer:
Step-by-step explanation:
9
The angles are vertically opposite. Vertically opposite angles are equal.
12x - 5 = 10x + 1 Add 5 to both sides.
12x = 10x + 5 + 1 Combine
12x = 10x + 6 Subtract 10x from both sides.
12x - 10x = 6 Combine
2x = 6 Divide by 2
x = 6/2
x = 3
10
Adjacent angles to each other when sharing a side are supplementary
4x + 7 + 2x + 5 = 180 Combine like terms on the left
6x + 12 = 180 Subtract 12 from both sides
6x = 180 - 12 Combine
6x = 168 Divide by 6
x = 168 / 6
x = 28

use the diagram on the right. How many planes contain both the line and the point
a. FG and point P
b. EP and point G
Part (a)
Answer: 0-------------------
Explanation:
Point P is part of 3 planes or faces of this triangular prism:
plane PEF (the front slanted plane)plane PEH (the left triangular face)plane PHG (the back rectangular wall)Notice how each three letter sequence involves "P", though this isn't technically always necessary. I did so to emphasize how point P is involved with these planes.
Each of the three planes mentioned do not involve line FG
Plane PEF only deals with point FPlane PEH doesn't have any of F or G involvedplane PHG only involves GSo there are no planes that contain line FG and point P.
==================================================
Part (b)
Answer: 0-------------------
Explanation:
It's the same idea as part (a) earlier. The planes involving point G are
plane GQF (triangular face on the right)plane GFE (bottom rectangular floor)plane GHP (back rectangular wall)None of these planes have line EP going through them.
As an alternative, we could reverse things and focus on all of the planes connected to line EP. Those 2 planes are
plane PEH (triangular face on the left)plane PEF (front slanted rectangular face)None of these planes have point G located in them.

Answer:
X should equal 12.
Step-by-step explanation:
I say this because we know TED= 30° bc 50°-20° = 30
then u have to think about what × 2 + 6 equals 30
sure enough 12 × 2 = 24 and 24 + 6 = 30
that's why I say X equals 12

Q9. Alice worked 52 hours this week. She gets paid $9.35 per hour for the
first 40 hours and then gets time-and-a-half for the rest of the time. How
much money did she make this week?
9514 1404 393
Answer:
$542.30
Step-by-step explanation:
For the first 40 hours, Alice made ...
(40 h)($9.35/h) = $374.00
For the next 52 -40 = 12 hours, Alice made ...
(12 h)($9.35/h × 1.5) = $168.30
Then the total Alice made for working 52 hours is ...
$374.00 +168.30 = $542.30
Alice made $542.30 this week.
