in a right triangle, 0 is an acute angle and tan 0=8/5. What is the exact value of cos 0?
Answer:
[tex]\cos\theta=0.53[/tex]
Step-by-step explanation:
Given that,
[tex]\tan\theta=\dfrac{8}{5}[/tex]
We know that,
[tex]\tan\theta=\dfrac{P}{B}[/tex]
Where
P is perpendicular and B is base
Let H is hypotenuse of triangle. Using Pythagoras theorem,
[tex]H^2=P^2+B^2\\\\H=\sqrt{P^2+B^2} \\\\H=\sqrt{8^2+5^2} \\\\H=9.43[/tex]
We know that,
[tex]\cos\theta=\dfrac{B}{H}\\\\\cos\theta=\dfrac{5}{9.43}\\\\\cos\theta=0.53[/tex]
So, the value of [tex]\cos\theta[/tex] is equal to 0.53.
Which graph represents y as a function of x?
Answer:
b
Step-by-step explanation:
=======================================================
Explanation:
Graph B, C and D all fail the vertical line test. If it's possible to pass a vertical line through more than one point on the curve, then it's said to have failed the vertical line test. Any vertical line itself therefore is automatically not a function. If a graph fails the vertical line test, then it is not a function.
A function is only possible if for any given input x, we have exactly one and only one output. For graph A, the output is the same value regardless of the input. This is a constant function.
For something like graph B, the input x = 0 produces three different y outputs. The output y = 0 is one of those, and the others are off the screen so it's hard to tell what they are. Turns out it doesn't matter and all we need to do is the vertical line test. Graphs C and D are a similar story. In the case of graph D, the only input x allowed is x = 2 and it produces infinitely many y outputs.

Step-by-step explanation:
On your calculator go to stat-edit and enter the table. Press stat and go over to calc then press 4 and hit calculate it will give you the answer.
The slope of the line that is these data is 0.03 or 3/100
The correct option is (B).
What is slope of line?The slope of a line is a measure of its steepness.
Given that:
Time Distance
50 1.5
200 6

Let us take,
[tex]x_1[/tex]=1.5, [tex]x_2[/tex]= 6, [tex]y_1[/tex]= 50, [tex]y_2[/tex]= 200
Slope of line, m= Δy/Δx
m= [tex]x_2[/tex]- [tex]x_1[/tex]/ [tex]y_2[/tex]- [tex]y_1[/tex]
m=6-1.5 /200-50
m=4.5 /150
m= 45/1500= 3/100
m=0.03
Hence, slope of line is= 0.03

What is true about the figure?
In the figure, angles C and D are a
Therefore, angle C must measure
B = ?
C = ?
A = ?
D = 124°
Answer:
<A = 56degrees
<B = 34degrees
<C = 56degrees
Step-by-step explanation:
From tyhe diagram, the sum of m<C and m<D is 180degrees. Hence;
<C + <D = 180
<C + 124 = 180
<C = 180 - 124
<C = 56degrees
Also;
<B + 90 + <C = 180
<B + 90 + 56 = 180
<B + 146 = 180
<B = 180 - 146
<B = 34degrees
Similarly;
<A + <B = 90
<A + 34 = 90
<A = 90 - 34
<A = 56degrees

A = 2(3p) = 6p
S = 3p - 10
add together:
3p + 6p + 3p - 10 = 12p - 10

population is increasing at a rate of 8% per
year. There is a concern that the food will be
scarce when the population doubles. How
long will it take for the population to reach
40,000. Show and explain your work.
Answer:
9 years
Step-by-step explanation:
by using the formula :
20,000(1 + 0.08) ^n = 40,000
=> (1.08)^n = 40,000/20, 000
(1.08) ^n = 2
n = 9

To find the area of a parallelogram you need to do base x height.
The height is 7, and the base of that height is 3.
7 x 3 = 21
Let me tell you why you do base x height.
if you cut out the triangle from the top and place it at the bottom it will become a rectangle.
The formula for a rectangle is base x height so this is why the formula works.

Step-by-step explanation:
x + x + 10 + 40 = 180 *combine like terms*
2x + 50 = 180
just in case:
2x + 50 = 180 *subtract 50 from both sides*
2x = 130 *divide by 2*
x = 65
