tan(theta)=40/58 How do u solve? How do u isolate theta? show work plz!
Answer:
34.60°
Step-by-step explanation:
[tex] \tan \theta = \frac {40}{58}[/tex]
[tex] \tan \theta = 0.689655172[/tex]
[tex] \theta =\tan^{-1} 0.689655172[/tex]
[tex] \theta =34.592288671\degree [/tex]
[tex] \theta =34.60\degree [/tex]
Answer:
[tex]\Large \boxed{\theta = 34.59228868\°}[/tex]
Step-by-step explanation:
tan(θ) = 40/58
To isolate theta (unknown angle), we must take the inverse tangent of both the sides.
tan^-1(tan(θ)) = tan^-1(40/58)
The inverse tangent and tangent cancels.
Simplify the equation.
θ = tan^-1(20/29)
θ = 34.59228868°

Jordan drives to the store at 30 miles per hour. On her way home she averages only 20 miles per hour. If the total rime takes half an hour, how far does she live from the store?
Answer:
10 miles away
Step-by-step explanation:
If she travels at only 20 miles per hour, and half of one hour is 30 minutes, then you would divide the amount of miles (20) by 2 to get 10. I'm sorry this isn't the best explanation, but I hope you understand what I am trying to say :((
Evaluate the function.
[tex]f(x) = - x^{2} - 7x - 5[/tex]
Find
[tex]f( - 5)[/tex]
===================================================
Explanation:
Everywhere you see an x, replace it with -5. Then use the order of operations PEMDAS to simplify
[tex]f(x) = -x^2 - 7x - 5\\\\f(-5) = -(-5)^2 - 7(-5) - 5\\\\f(-5) = -(25) - 7(-5) - 5\\\\f(-5) = -25 + 35 - 5\\\\f(-5) = 10 - 5\\\\f(-5) = 5\\\\[/tex]
Keep in mind that for the x^2 term, you are squaring all of x = -5, which includes the negative as well. So that means
x^2 = (-5)^2 = (-5)*(-5) = 25
but sticking a negative out front makes
-x^2 = -(-5)^2 = -25
Write the equation of a line that passes a given point and has the given slope. Answer in standard form. 1. Point (-3,5), m = -7 2. Point (4,7), m = 0
Answer:
y -5 = -7(x +3)y = 7Step-by-step explanation:
The point-slope form of the equation can be used for this. It is generally written as ...
y -k = m(x -h) . . . . . line with slope m through point (h, k)
__
1. For m=-7, (h, k) = (-3, 5), the equation is ...
y -5 = -7(x +3)
__
2. For m=0, (h, k) = (4, 7), the equation is ...
y -7 = 0(x -4)
y = 7
_____
Comment on the form of the answer
Since a point and slope are given, "the equation" is appropriately written in point-slope form. For the second problem the simplified version would be ...
y -7 = 0
Sometimes, "the equation" means the answer is expected in slope-intercept form. In that case, a little rearranging is necessary for the first answer. It becomes ...
y = -7x -16
There are perhaps a dozen different forms that a linear equation can be written in. Considering those, "the equation" is somewhat ambiguous. Your curriculum materials may offer a clue as to the form intended.

What is X I need help i dont know how to do this
Answer:
x = 75
Step-by-step explanation:
Triangle BDH
The angle must add to 180 degrees
36+ 39 + DHB = 180
75 + DHB = 180
DBH = 180-75
DHB = 105
DBH + x = 180 since it is a straight line
105+ x = 180
x = 75

Answer:
x = 10 x = -2
Step-by-step explanation:
(x-4)^2 -28 = 8
This is a parabola on the left and a constant line on the right. The parabola will cross the line twice, so there will be two solutions
see attached
Add 28 to each side
(x-4)^2 -28+28 = 8+28
(x-4)^2 = 36
Take the square root of each side
sqrt((x-4)^2) = ±sqrt(36)
x-4 = = ±6
Add 4 to each side
x-4+4 = 4±6
x = 4+6 x = 4-6
x = 10 x = -2
Answer:
x = 10, and x = - 2
Step-by-step explanation:
This equation has two solutions, as it resembles a quadratic equation. When graphed it will be a parabola, and hence intersects the x - intercept at two points, giving us two solutions.
Let's start by expanding the equation,
(x - 4)² - 28 = 8,
(x - 4)² = 28 + 8,
(x - 4)² = 36,
x - 4 = √36, and x - 4 = - √36
x - 4 = 6, and x - 4 = - 6
Solution(s) : x = 10, and x = - 2

Answer:
-7 is less than or equal to 0
Step-by-step explanation:
range is looking at the correlation on the graph from left to right. At -7, there is a dot and at 0, there is a dot. The graph is not continuous, so that is the answer.
The graph shows the relationship between the height of a tree and its age in years. What is the unit rate of growth for the tree? 0.25 feet per year 0.5 feet per year 2 feet per year 3 feet per year
Answer:
The unit rate is 2 feet per year
Step-by-step explanation:
The graph is missing (See attachment)
To determine the unit growth;
First, we have to pick any two corresponding on the x and y axis
When x = 5; y = 10
When x = 1; y = 2
These can be represented as;
[tex](x_1,y_1) = (5,10)[/tex]
[tex](x_2,y_2) = (1,2)[/tex]
Next, is to determine the slope using;
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute values for x and y
[tex]m = \frac{2 - 10}{1 - 5}[/tex]
[tex]m = \frac{-8}{-4}[/tex]
[tex]m = 2[/tex]
Hence, the unit rate is 2 feet per year
Answer:
the unit rate is 2ft per year i got 100% on a quiz for this

20+3(7+4)+5+2(7+9)?????
Answer:
90
Step-by-step explanation:
Be sure to use PEMDAS. Begin with parentheses, the move to multiplication, then adding.
20 + 3(7 + 4) + 5 + 2(7+9)
20 + 3(11) + 5 + 2(16)
20 + 33 + 5 + 32
You can add those final four numbers in any order you want, to get a sum of 90.
Answer:
Your answer will be 90
Step-by-step explanation
First you will have to answer what's inside the parentheses
7 + 4 = 11 , 7 + 9 = 16
Then you multiply what is next to the parentheses
3×11 = 33, 2×16 = 32
Finally you will have to add
20 + 33 =53
53 + 5 =58
58 + 32 = 90
The point is doing PEMDAS

Anna was driving east on a freeway at a constant velocity. She was 570 kilometers west of
her exit. In 2 hours, she drove one-third of the way to her exit. What was her velocity?
Answer:
Her velocity is 95 km/hour
Step-by-step explanation:
The given information includes;
The direction to which Anna was driving = Eastward
Her initial location on the journey = 570 kilometres west of her her exit
The distance she drove in 2 hours = 1/3 of the way to her exit
Therefore, the distance she drove in 2 hours = 1/3×570 = 190 m
Her velocity = Her distance covered/(The time it take to cover the distance)
Which gives;
Her velocity = (190 km)/(2 hours) = 95 km/hour
Her velocity = 95 km/hour.

You need to find the GCF (greatest common factor) of 45 and 90, which is 45.
45 times ? gets you 45
? would be 1
45 times 1 equals 45.
45 times ? gets you 90
? would be 2
45 times 2 equals 90
45(1+2) = 45+90 = 135
♡ Hope this helps! ♡
❀ 0ranges ❀
Answer:
45(1 + 2)
Step-by-step explanation:
To find the greatest common factor, we find the multiples of 45 and 90.
45: 1, 3, 5, 9, 15, 45
90: 1, 2, 3, 5, 6, 9, 15, 18, 45...
The easier way to do this is divide 90 by 2 to get our GCF, 45.
We place the 45 (GCF) in the first box and we place 1 and 2 in the parentheses because when you distribute, we get our original answer.
45(1 + 2)

Functions stuff. Picture attached. 30 points. thanks <3
Answer:
A
Step-by-step explanation:
So we have the function:
[tex]f(x)=\frac{3+x}{x-3}[/tex]
And we want to find:
[tex]f(a+2)[/tex]
To do so, substitute in (a+2) for x:
[tex]f(a+2)=\frac{3+(a+2)}{(a+2)-3}[/tex]
Simplify the numerator and denominator. Add 2 and 3 in the numerator. Subtract in the denominator:
[tex]f(a+2)=\frac{5+a}{a-1}[/tex]
The answer is A.
Answer:
[tex]\Large \boxed{\mathrm{A}}[/tex]
Step-by-step explanation:
[tex]\displaystyle f(x) = \frac{3+x}{x-3}[/tex]
For f(a + 2), the input for the function f(x) is (a + 2).
Replacing x with (a + 2).
[tex]\displaystyle f(a+2) = \frac{3+(a+2)}{(a+2)-3}[/tex]
Simplify the rational function.
[tex]\displaystyle f(a+2) = \frac{(3+2)+a}{a+(2-3)}[/tex]
[tex]\displaystyle f(a+2) = \frac{5+a}{a-1}[/tex]

What is the volume of the following prism?
A. 96 in³
B. 480 in³
C. 48 in³
D. 108 in³
Answer:
C
Step-by-step explanation:
To find the volume, we can multiply the area of the base by the height. The base is a triangle so its area is (4 * 3) / 2 = 6 and the height is 8 so the volume is 6 * 8 = 48 in³.
Answer:
C. Vol = 48 in³
Step-by-step explanation:
Vol = base area of a triangle x height.
Vol = ( 1/2 * 3 * 4 ) x 8
Vol = 48 in³
If g(x)= x^2-2x-6 and h(x)= 2x^2-5x+2 find (h-g) (-2)
Answer:
[tex](h - g)( - 2) = 18[/tex]Step-by-step explanation:
g(x) = x² - 2x - 6
h(x) = 2x² - 5x + 2
To find (h-g) (-2) we must first find h - g(x)
To find h - g(x) subtract g(x) from h(x)
We have
[tex](h - g)(x) = {2x}^{2} - 5x + 2 - ( {x}^{2} - 2x - 6) \\ = {2x}^{2} - 5x + 2 - {x}^{2} + 2x + 6 \\ = {2x}^{2} - {x}^{2} - 5x + 2x + 2 + 6[/tex][tex](h - g)(x) = {x}^{2} - 3x + 8[/tex]To find (h-g) (-2) substitute the value of x that's - 2 into (h - g)(x) that's replace every x in (h - g)(x) by - 2
That's
[tex](h - g)( - 2) = ({ - 2})^{2} - 3( - 2) + 8 \\ = 4 + 6 + 8 \\ = 10 + 8[/tex]We have the final answer as
[tex](h - g)( - 2) = 18[/tex]Hope this helps you
