Answer:
132
Step-by-step explanation:
That is an 180 degree angle so just do:
180-42=a
a=132
Answer:
138 degrees.
Step-by-step explanation:
A straight line is equal to 180 degrees. 42 is some, so you would subtract 180 and 42. That is 138 degrees. (When two or more angles add up to 180 it's called supplementary angle) Hope this helps

A rose bush of height `h` is planted at an initial height of 3 feet. The bush is expected to grow an average of 0.5 feet per year. How tall will the bush be 3 years after planting? Show the work that leads to your answer (either in the text box below or on the white board to the right).
Answer:
The height is 4.5ft
Step-by-step explanation:
Given
[tex]Initial\ Height = 3\ ft[/tex]
[tex]Growth = 0.5\ ft[/tex] yearly
Required
Determine the height in 3 years
First, we need to determine the growth equation.
Represent the height with h and the years with x
So:
[tex]y = Initial\ Height + Growth * x[/tex]
[tex]y = 3 + 0.5 * x[/tex]
[tex]y = 3 + 0.5x[/tex]
To solve the required, we have that:
[tex]x = 3[/tex]
[tex]y = 3 + 0.5x[/tex] becomes
[tex]y = 3 + 0.5 *3[/tex]
[tex]y = 3 + 1.5[/tex]
[tex]y = 4.5[/tex]
Hence, the height is 4.5ft

What are the measures of the angles in the triangle? (6x + 10) (x + 17) (4x - 34)
I'm not quite sure these are right. You might wanna check with a classmate or something first.
Step-by-step explanation:
(6x + 10) + (x + 17) + (4x - 34) = 180
11x - 7 = 180
11x = 173
x = 15.73 (answer had repeating decimal so i rounded up in the hundredths place)
(6x + 10)
6 (15.73) + 10
94.38 + 10
104.38
(x + 17)
(15.73) + 17
32.73
(4x - 34)
4(15.73) - 34
62.92 - 34
28.92

p= Paul Sally = 5p
5p -10 = p+10
4p = 20
p = 5
Now Paul has 15 and Sally has 15 too
Find DY divided by DX by implicit differentiation y=sinxy 
Answer:
Step-by-step explanation:
[tex]y = sin(xy)\\\frac{d}{dx}y=cos(xy)(\frac{d}{dx}(xy))\\ \frac{d}{dx}y = cos(xy)(y + x*\frac{d}{dx}y)\\ write \: \frac{d}{dx}y \: as\:y'\\y' = cos(xy)(y+xy')\\y' = ycos(xy) + xy'cos(xy) \\y'-xy'cos(xy) = ycos(xy)\\y'(1-xcos(xy)) = ycos(xy)\\\\y' = \frac{ycos(xy)}{1-xcos(xy)}[/tex]

A) q = 1 and q = -8
B) q = -1 and q = 8
C) q = -1 and q = 4
D) q = 1 and q = -4
Answer:
I looked it up it is C x=-1 and x=4,Download "" from app store or play store, you can just take a picture and the answer will pop up
Step-by-step explanation:
The given function is not defined for [tex]q=-1,q=4[/tex]
Option C is correct.
Domain of function:It is defined as the all input values for which function is defined.
Given function are,
[tex]\frac{q^{2}+7q-8 }{q^{2} -3q-4}[/tex]
Above function is not defined where denominator of function will be zero.
[tex]q^{2}-3q-4=0\\ \\q^{2}-4q+q-4=0\\ \\q(q-4)+1(q-4)=0\\\\(q+1)(q-4)=0\\\\q=-1,q=4[/tex]
Thus, given function is not defined for [tex]q=-1,q=4[/tex]

Answer:
X Intercept: (-2, 0)
Y Intercept: (0, 7)
Explanation:
Plug y = 0 into the equation and solve the resulting equation 7x = −14 for x. Plug x = 0 into the equation and solve the resulting equation −2y = −14 for y.
Answer:
(- 2, 0 ) and (0, 7 )
Step-by-step explanation:
To find the x- intercept let y = 0 in the equation and solve for x
7x - 2(0) = - 14, that is
7x = - 14 ( divide both sides by 7 )
x = - 2 ⇒ (- 2, 0 ) is the x- intercept
To find the y- intercept let x = 0 in the equation and solve for y
7(0) - 2y = - 14, that is
- 2y = - 14 ( divide both sides by - 2 )
y = 7 ⇒ (0, 7 ) is the y- intercept
