Answer:
√41
Step-by-step explanation:
Pythagorean Theorem:
a^2+b^2=c^2
4^2+5^2=c^2
16+25=c^2
41=c^2
√41=c
Solve the equation by subtracting the appropriate number from both sides and enter the value of x below. x + 45 = 97 x = _____
Solution:
Your problem → x + 45 = 97x
x+45=97x
⇒-96x+45=0
⇒96x=45
⇒x=45/96
⇒x=15/32

Sean went bike riding yesterday. Use the graph below to determine how fast he was riding in miles per hour.
Answer:
12 miles per hour.
Step-by-step explanation:
1. If you pick 5 hours, then you will noticed that the graph shows you 60 miles.
2. Find the unit rate.
5 hours = 60 miles
1 hour = x miles
x= 60 ÷ 5
x= 12 miles per hour
Par on a golf course is 72. If a golfer shot rounds of 74, 67, and 73 in a tournament, what will she need to shoot on the final round to average par?
Answer:
74
Step-by-step explanation:
By average definition:
(74 + 67 +73 +x) / 4 = 72
Multiply by 4
(74 + 67 +73 +x) = 288
shift the first three terms on the right side
x = 288 -74 -67 -73 = 74

A building has a second floor window 27 ft above the ground. A fireman brings his 33 foot ladder to lean against the wall to reach the window.
The reference angle will be the angle formed by the ladder and the ground.
[[Word List: Adjacent, Cosine, Hypotenuse, Opposite, Sine, Tangent]]
(a) In this scenario, the ladder represents the ______ of the triangle.
(b) The height of the window is the ________ side of the triangle
(c) The correct trigonometry ratio to use for this scenario is _______.
(d) The reference angle must be between 70 and 80 degrees for the ladder to be safe to climb. Use trigonometry and solve for the reference angle to the nearest whole degree. Is the ladder safe? (show work)
(e) The ladder is adjustable in 1-foot increments. What length does it need to be in order to be safe according to part D? (show work)
The ladder makes an angle 30 degrees with the ground
Data;
Length of the ladder (hypothenuse) = 30 ft
height of the wall (opposite) = 15 ft
When the ladder reclines on the wall, it forms a right-angle triangle and we can solve it.
Using SOHCAHTOA,
We have the value of hypothenuse and opposite and we can use the sine angle of this triangle.
The ladder makes an angle 30 degrees with the ground.

I WILL MARK YOU BRAINLIEST IF ANSWERED CORRECTLY IF YOU DO NOT KNOW THE ANSWER PLS DONT COMMENT ON THIS THREAD
Answer:
? = 13. 35
Step-by-step explanation:
By using Pythagorean Theorem
H² = P² + B ²
=> 17² = P² + 10²
=> 289 = P² + 100
=> 289 - 100 = P²
=> 189 = P²
=> √189 = P
or P = 13.75
The length breadth and height of a sectangular box are 24 cm, 6 cm and 2cm respectevely. Find the area of largest surface of box?
Answer:
[tex]408cmx^{2}[/tex]
Step-by-step explanation:
A=2(wl+hl+hw)=2·(2·6+24·6+24·2)= 408cm²
length= 6
width= 2
height= 24
to find:the area if the box.
solution:[tex]a = lwh[/tex]
[tex]a = 2(wl + hl + hw)[/tex]
[tex]a = 2 \times (2.6 + 24.6 \times + 24.2)[/tex]
[tex]a = 408 {cm}^{2} [/tex]
therefore, the area of the box is 408 square centimeters.

Let f (x) = 7+3 and g(x) = Vx+5. What is the domain of (fºg)(x)?
Answer:
[-5, 4) ∪ (4, ∞)
Step-by-step explanation:
Given functions:
[tex]f(x)=\dfrac{1}{x-3}[/tex]
[tex]g(x)=\sqrt{x+5}[/tex]
Composite function:
[tex]\begin{aligned}(f\:o\:g)(x)&=f[g(x)]\\ & =\dfrac{1}{\sqrt{x+5}-3} \end{aligned}[/tex]
Domain: input values (x-values)
For [tex](f\:o\:g)(x)[/tex] to be defined:
[tex]x+5\geq 0 \implies x\geq -5[/tex]
[tex]\sqrt{x+5}\neq 3 \implies x\neq 4[/tex]
Therefore, [tex]-5\leq x < 4[/tex] and [tex]x > 4[/tex]
⇒ [-5, 4) ∪ (4, ∞)

PLEASE HELP REALLY NEED IT RIGHT NOW WILL GIVE CORRECT WORK WITH ANSWER BRAINIEST Find the area of X and show your work !!
Answer:
x = 6.40
Step-by-step explanation:
The formula to find the area of the rectangle is :
Area = Length × Width
Given that,
Area ⇒ 50
Length ⇒ ( 2x - 5 )
Width ⇒ x
So now we can write an expression like this.
Area = Length × Width
50 = x ( 2x - 5 )
And now we can solve for x.
Let us solve now by using the completing square method.
x ( 2x - 5 ) = 50
2x² - 5x = 50
First divide the whole equation by 2.
x² - 2.5 = 25
x² - 2.5 + 1.5625 = 25 + 1.5625
( x - 1.25 )² = 26.5625
x - 1.25 = ±√26.5625
x - 1.25 = ±5.1538
So,
x = + 5.1538 + 1.25 or x = - 5.1538 + 1.25
x = 6.40 x = -3.90
As we cannot get a negative number as a value for length,
x = 6.40
