can someone please explain, i really need help
Answers
Answer:
x = 42.5
Step-by-step explanation:
A triangle formed inside of a circle using the diameter as one of its side lengths is a right triangle
The right angle would be the angle opposite of the diameter (∠C)
A right angle has a measure of 90°
That being said we use this equation to solve for x
90 = 2x + 5
step 1 subtract 5 from each side
90 - 5 = 85
5 - 5 cancels out
now we have 85 = 2x
step 2 divide each side by 2
85/2=42.5
2x/2=x
we're left with x = 42.5

What is the average rate of change for this function for the interval x=2 to x=4?
Answers
Answer:
12
Step-by-step explanation:
The average rate of change in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 2, 4 ]
f(b) = f)4) = 32 ← from table

Answers
Answer:
A) y=2x-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(9-5)/(6-4)
m=4/2

if in a triangle ac= 15 and angle abc=60 degrees what is ab?
Answers
Answer:
∠A=30° and AC and BC is 13 and 7.5 units respectively
Step-by-step explanation:
Given that in a right triangle ABC , right angled at C , if angle B =60 degree and AB =15 units
we have to find the remaining angles.
By angle sum property, sum of angles in right angle is 180°
∠A+∠B+∠C=180°
∠A+ 60°+90°=180
∠A=180°-150°=30°
∠A=30°
As AB= 15
Now by trigonometric ratios we find the other sides of triangle ABC
Hence, ∠A=30° and AC and BC is 13 and 7.5 unitsStep-by-step explanation:

he baseball team pitcher was asked to participate in a demonstration for his math class. He took a baseball to the edge of the roof of the school building and threw it up into the air at a slight angle so that the ball eventually fell all the way to the ground. The class determined that the motion of the ball from the time it was thrown could be modeled closely by the function
h(t)=16t^2+64t+80
Where h(t) represents the height of the ball in feet after t seconds.
1. By looking at the equation, how can you determine whether the function has a maximum or a minimum value? (1 point)
2. Find the maximum or minimum value of the function algebraically. After how many seconds did the ball reach this value? Show how you found your answers. (2 points)
3. Evaluate h(0). Explain this value in the context of the problem. (1 point)
4. How long is the ball in the air? Justify your answer. (2 points)
5. State the domain of the function in interval notation, and explain the restrictions on the domain based on the context of the problem. (2 points)
