Answer:
sin 4/9 if cos is 3/5
Step-by-step explanation:
A cosine function is equivalent to the adjacent side divided by the hypotenuse , from SOH-CAH-TOA.
So, our adjacent side can be 3 , and the hypotenuse can be 5.
Then, we can use the Pythagorean theorem (a^2 + b^2 = c^2) to find the missing side length.
3^2+b^2=5^2
9+b^2 =25
b^2=16
b = 4
We found our three sides: 4, 5, and 9.
We know from SOH-CAH-TOA that the sine function is equivalent to the opposite side length divided by the hypotenuse length. So:
sin θ = 4/9

The midpoint of QR is (4, -1).
Q = (3.1)
What are the coordinates of point R?
Answer:
(5,-3)
Step-by-step explanation:
Given that,
The coordinates of Q = (3,1)
The midpoint of QR = (4,-1)
We need to find the coordinates of point R.
We know that, according to mid-point theorem,
[tex](x_m,y_m)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
Let (x₂,y₂) be the coordinates of point R.
So,
[tex](4,-1)=(\dfrac{3+x_2}{2},\dfrac{1+y_2}{2})\\\\\dfrac{3+x_2}{2}=4\ and\ \dfrac{1+y_2}{2}=-1\\\\3+x_2=8\ and\ y_2+1=-2\\\\x_2=5\ and\ y_2=-3[/tex]
So, the coordinates of point R is (5,-3).
Evaluate the function requested. Write your answer as a fraction in lowest terms.
B
82
18
A
80
Find cos B.
Answer:
[tex]\cos B=\dfrac{9}{41}[/tex]
Step-by-step explanation:
Given that,
Hypotenuse = 82 units
Base = 80 units
Height = 18 units
We need to find the value of cos B.
We know that,
[tex]\cos\theta=\dfrac{Base}{Hypotenuse}[/tex]
For angle B, Hypotenuse = 82 units, Height = 80 units and base = 18 units
[tex]\cos B=\dfrac{18}{82}\\\\\cos B=\dfrac{9}{41}[/tex]
Hence, the correct option is (A).

What is the surface area of the rectangular prism shown below?
5 cm
3 cm
13 cm
R
A 238 ft
B 400 ft
© 195 ft
D 119 ft?
Please someone help
Answer:
A
Step-by-step explanation:
That is because the surface area requires us to add all the areas of each side together. Therefore, you must take (5*3)+(5*3)+(13*5)+(13*5)+(13*3)+(13*3) = 238.

A drawing of a building is 12-inches high. The scale in the drawing shows 1/2 inch equals 100 feet. What is the actual height, in feet, of the building?
Answer:
200ft
Step-by-step explanation:
100ft = 1/2 ft
12in = 1 ft
1/2 * 2= 1ft
1ft or 12in = 200ft

please help :(( image attached! algebra 2
Answer:
0 ; -3 ; -8
Step-by-step explanation:
If we look at the expression we can see that we have two fractions. If one f the denominators is equal to 0, the expression is impossible. So we have to find the values of x that make the denominators equal to 0 and exclude them.
3x^2 + 6x = 0
divide the two members for three
x^2 + 3x = 0
factorize x
x(x +3) = 0
a product is equal to 0 when at least one of the factors is equal to 0, so we have two solutions:
x = 0
x + 3 = 0 ; x= -3
0 and -3 can’t be values of x
x^2 + 11x + 24 = 0
For simplify the work we can factorise the trinomial:
We have to find two numbers whose sum is 11 and whose product is 24
the two numbers are 3 and 8, so we can rewrite the trinomal as:
(x+3)(x+8) = 0
for the consideration made above, we can find
x = -3
x = -8
so the final answer of the question is
0 ; -3 ; -8
On a trip across the country Joe used 20 gallons of gas to go 300 miles. At this rate, how much gas must he use to go 3600 miles?
HELP
Answer:
240 gallons
Step-by-step explanation:
Let's set up an ratio where g = gallons and m = miles:
20g = 300m
We need the right side of that to be 3600, so multiply both sides by 12:
12(20g) = 12(300m)
Answer: 240 gallons for 3600 miles

Solve 169x^2-42.25=0 by using square roots?
NEED HELP!!!
Answer:
x = 1/2 , x = -1/2
Step-by-step explanation:
Given equation;
169x² - 42.25
Find:
Solution of equation using square root
Computation:
169x² - 42.25
We know that 13² = 169 and 6.5² = 42.25
So,
[13x]² - [6.5]²
a² - b² = (a + b)(a - b)
So,
[13x]² - [6.5]² = [13x + 6.5][13x - 6.5]
So,
13x + 6.5 = 0 , 13x - 6.5 = 0
x = 6.5 / 13 , x = -6.5 / 13
x = 1/2 , x = -1/2
