Step-by-step explanation:
[tex]\angle BOC+\angle AOB=90^\circ $(Complementary Angles)\\6x - 6^\circ+5x + 8^\circ=90^\circ\\6x+5x-6^\circ+ 8^\circ=90^\circ\\11x+ 2^\circ=90^\circ\\11x=90^\circ-2^\circ\\11x=88^\circ\\$Divide both sides by 11\\x=8^\circ\\$Therefore:\\m\angle BOC=6x - 6^\circ\\=6(8) - 6^\circ\\=48-6\\=42^\circ[/tex]
The measure of angle BOC is 42 degrees.
Answer:
BOC = 42º
Step-by-step explanation:
Angle BOC is equal to 42 degrees, due to these steps -
1. Create the equation which will result to be -
6x - 6 + 5x + 8 = 90
2. Simplify by adding variables and numbers together -
11x + 2 = 90
3. Subtract 2 from both sides to get -
11x = 88
4. Divide by 11 on both sides to get-
x = 8
5. Substitute x in angle BOC as 8 to get this equation -
6(8) - 6
6. Solve
48 - 6 =
42º
Your final answer for angle BOC is 42º!

Answers
Answer: g(x)=(x+7)²-2
Step-by-step explanation:
For this problem, you will need to know what each part fo the function does. You can see that g(x) is the bottom function and f(x) is the to function. F(x) has traveled down to -2. You know that the y-intercept is -2. The only answer choice with -2 as y-intercept is g(x)=(x+7)²-2.
Answer:
g(x) = (x + 7)^2 -2
Step-by-step explanation:
f(x) = (x + 7)^2
We are shifting the function down 2 units
f(x) -b where b is 2
g(x) = f(x) -2
g(x) = (x + 7)^2 -2

Sophie and Jackson are reading the same book. At the beginning of the month, Sophie was on page 20 and Jackson was on page 50. Sophie will read 10 pages per day and Jackson will read 5 pages per day. Let S represent the page of the book that Sophie is on at the end of t days into the month, and let J represent the page of the book that Jackson is on at the end of t days into the month. Graph each function and determine after how many days t Sophie and Jackson will be on the same page of the book.
Answers
Answer:
t = 6 days
Step-by-step explanation:
We can model both cases with linear equations in the form:
y = ax + b
Sophie was on page 20 and she reads 10 pages per day, so her equation is:
S = 20 + 10t
Jackson was on page 50 and he reads 5 pages per day, so his equation is:
J = 50 + 5*t
The graph of those equations are in the image attached (The blue line is for Sophie and the orange line is for Jackson)
To find after how many days they will be on the same page, we can make S = J and then find the value of t:
20 + 10t = 50 + 5t
5t = 30
t = 6 days

A fish jumps out of water. The function y = −16t 2 + 11t models the height, in feet, of the fish above water after t seconds. A) How long is the fish out of water? B) What is the maximum height of the fish above the water?
Answers
Answer:
A) The fish was out of water for 0.6875 seconds.
B) Maximum height = 5.672
Step-by-step explanation:
Height is modeled by;
y = -16t² + 11t
A) To find total time of the fish out of water, we need to find the x - intercept. That is the points where y = 0
So, 0 = -16t² + 11t
So the roots of this equation are;
t = 0 or 0.6875
Thus,the fish was out of water for 0.6875 seconds.
B) y = -16t² + 11t
The x coordinate of the vertex is at - b/2a
For y = -16t² + 11t
a = -16, b = 11, c = 0
So, -b/2a = -11/(2*-16) = 11/32
The maximum height will be at the y-coordinate of the vertex.
Thus, we need to find f(11/32)
f(11/32) = -16(11/32)² + 11(11/32) = 1.890625 + 3.78125 = 5.671875 ≈ 5.672

Answers
Answer:
36 like iphone only
Step-by-step explanation:
You know that 40 people like both so you can already get them out of the way. That leaves you with 60 people and if we are dividing them into 5ths then 1/5 = 12 people. If the ratio is 3:2 then you can just multiply 3 x 12 to get 36 and then 2 x 12 to get 24 and that equals 60 and added to your 40 who like both, you get 100 students.

A ball is kicked from an initial height of 2.5 feet with an initial velocity of 45 feet per second. The function ƒ(x) = −16x^2 + 45x + 2.5 models its
path, where x is the time (in seconds) the ball travels and ƒ(x) is the height (in feet) the ball is kicked. What is the height of the ball 2 seconds after it is kicked?
Answers
Answer:
28.5 ft
Step-by-step explanation:
The height of a ball is given by the equation ƒ(x) = −16x² + 45x + 2.5 where x is the tome the ball travels. To find the height of the ball after a seconds, we substitute a in place of x, the equation becomes:
ƒ(a) = −16a² + 45a + 2.5.
Therefore if the height of the ball is needed to be found after 2 seconds, we find f(2).
ƒ(2) = −16(2)² + 45(2) + 2.5 = -64 + 90 + 2.5 = 28.5 ft
f(2) = 28.5 ft

What is linear equation?
When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."
Both linear equations with one variable and those with two variables exist.
Given equations,
y = x + 2
y = x² + 5x + 6
substitute value of y in second equation
x + 2 = x² + 5x + 6
x² + 4x + 4 = 0
x² + 2x + 2x +4 = 0
x(x +2) + 2(x + 2) = 0
(x + 2)(x + 2) = 0
x = -2
and y = x + 2
y = -2 + 2 = 0
Hence, the solution of equation is at x = -2 and y = 0.
