The answer is 71 degrees
Step-by-step explanation:
Answer:
C. 71°
Step-by-step explanation:
In order to find its reference angle, we first need to find its corresponding angle between 0° and 360°. This is easy to do. We just keep subtracting 360 from it until it's below 360. For instance, if our angle is 544°, we would subtract 360° from it to get 184° (544° – 360° = 184°).
In this case, our angle is -289°. 360 - 289 = 71°

What is the revenue of the company when it
spends $15 million on advertising? Show work
Answer:
$32 million
Step-by-step explanation:
I'm assuming the data set is in millions of dollars. Using some quick logic, the formula is revenue = (advertising)(2) + 2
R = 15(2) + 2R = 30 + 2R = 32 ($32 million?)3x + y = 4
8x + 2y = 10
Answer:
I take it that we solve for x and y, so we have
3x + y = 4, so we have y = 4 - 3x
and plug that in to
8x + 2y = 10
8x - 6x + 8 = 10
so
2x = 2
x = 1
y = 4 - 3
y = 1
suppose that grade point averages of undergraduate students at one university bell-shaped distribution with a mean of 2.57 and a standard deviation of 0.4 describe where approximately 99.7% of a grade point averages lie
Answer:
2.57-0.4-0.4-0.4=1.37
2.57-0.4-0.4=1.77
so the answer is 1.37 between 3.77

To find 5, realize angles 5 and 8 equal 180, because they make up a straight line, line d.
180-105=75
To find 11, it is the same as finding 7. Just look at the similar sizes. Angle 7 is the same at angle 5, just turned around. There’s a term for this pair angles that I don’t remember now but it exists. Now, lines a and b are parallel, so their angles between lines that intersect both are the same too. This means, as angle 5 equals angle 7, angle 7 equals angle 11.
To find 16, we use a combination of the methods used in finding the previous angles.
180-115=65 degrees is angle 4
Angle 4=Angle 16
Knowing the two angles given and that lines a and b are parallel, you could find the measurements of every angle in each intersection if you wanted to.

m5=75 degrees
m11=75 degrees
m16=65 degrees

Answer:
3) 35.98
4) 63.98

4) (7+7)×3.14+14×3=63.98
The formula v=√ 2gh gives the velocity v, in feet per second, of an object when it falls h feet accelerated by gravity g, in feet per second squared. If g is approximately 32 feet per second squared, find how far an object has fallen if its velocity is 48 feet per second.
Hi there!
[tex]\large\boxed{36 \text{ feet}}[/tex]
v = √2gh
Plug in the given velocity and acceleration due to gravity:
48 = √2(32)h
Square both sides:
2304 = 2(32)h
Simplify:
2304 = 64h
Divide both sides by 64:
h = 36 feet.

Find the Area of the Shaded Region.
Round to the nearest tenth if necessary.
18 m
25 m
5 m
50 m
9514 1404 393
Answer:
610 m²
Step-by-step explanation:
If we extend the horizontal line across the right-hand portion of the figure, then the figure is divided into two rectangles:
bottom: 5 m × 50 m = 250 m²
top: 18 m × 20 m = 360 m²
The sum of these areas is the shaded area:
shaded area = 250 m² +360 m² = 610 m²

Find the roots/zeroes of the following polynomial
x^2−19=6
Answer:
x=5 and x=-5
Step-by-step explanation:
1. first you would subtract 6 from both sides to set the equation = to zero.
2. The equation would then be x^2-25=0.
3. that is a difference of two squares polynomial. So when you factor it, it is (x+5)(x-5)=0
4. by the zero product property, the roots are 5 and -5.

POSITIVE LINEAR, negative linear, nonlinear ,none.
Answer:
From left to right:
Negative, positive, none, nonlinear
1 is negative bc it has a negative slope
2 is positive because it has a positive slope
3 has no correlation because there is no pattern
4 is no linear because it’s not in a line, essentially. (This would be a parabola)

So, if ya wanna solve this question and of course questions alike, ya gotta pay attention to the graph. mean All of these parabolic chart have the domain of R
Step-by-step explanation:
So there ya go
D=R
and now bout the range ya gotta find the vertex, which is:
[tex] x = \frac{ - b}{2a} \: \: y = \frac{Δ}{4a} [/tex]
now pay attention
X=2/–2=–1
y=–(–1)²–2(–1)+3=4
Now the highest point of your parabolic chart is 4 and the lowest point is endless which is (–♾,4]
Well, finally your answer is D
