Answer:
the angle is = 50
Step-by-step explanation:
8x+2+70+60=180° (interior angles of a triangle add up to 180°)
8x+132=180
8x=180-132
8x=48
divide with the coefficient of x both sides
x=6
substitute
(8(6)+2)+70+60=180
50+70+60=180
180=180

The pair of equations below is a result of constructing the altitude, h, in Triangle ABC is A; sin C = h/a and sin A = h/c.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
We know:
[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}[/tex]
So from the attached figure;
sin C = h/a
sin A = h/c
These expressions have an h term in common. We can combine them if we can find forms of the expressions in terms;
h = a (sin C)
h = c (sin A)
Thus, option A is correct pair.

A telecommunications company in a small town had 450 phone subscribers before they introduced a plan for newly joining members. The company recorded an approximate 50% increase each month in the number of new phone subscribers, where they had one new subscriber at the start of the plan. The number of phone subscribers x months after the plan was launched is modeled by the function below.
Answer:
450 x (1 + 0.5) ^ X = Phone subscribers
Step-by-step explanation:
Since a telecommunications company in a small town had 450 phone subscribers before they introduced a plan for newly joining members, and the company recorded an approximate 50% increase each month in the number of new phone subscribers, where they had one new subscriber at the start of the plan, to determine the number of phone subscribers x months after the plan was launched, the following function must be considered and solved:
450 x (1 + 0.5) ^ X = Phone subscribers
So, for example, in 3 months, the number of subscribers would be the following:
450 x (1 + 0.5) ^ 3 = 1,518.75
Thus, in 3 months, the company would have 1,518 subscribers.

Keenan bought 9 books about plants and 6 books about fish. He also bought 8 science magazines. Each book cost $20 and each magazine cost $3. How much did Keenan spend in all?
Answer:
$324
Step-by-step explanation:
Cost per books = $20
Book cost = $20 * (9 + 6) = 20 * 15 = $300
Cost per magazine = $3
Number of magazines = 8
Magazone cost = 8 * $3 = 24
Total cost = $300 + $24
= $324
Which equation can be simplified to find the inverse of y = 2x²?
O1/y=2x²
Oy=1/2x²
O-y= 2x²
O x= 2y²
Answer:
y=1/2x²
Step-by-step explanation:
y=2x-²
y=1/2x²
The equation can be simplified to find the inverse of y = 2x² is y=1/2x², the correct option is B.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
Equation y = 2x²
Now,
To find the inverse of a function, you need to swap the x and y variables and solve for y. So, the equation that can be simplified to find the inverse of y = 2x² is x = 2y². You can simplify it by dividing both sides by 2 and taking the square root of both sides. The inverse function is y = ±√(x/2).
Therefore, by the equation the answer will be y=1/2x²

Question 18 options:
A)
9.850
B)
18.610
C)
65.825
D)
124.365
Answer:
[tex]\Huge\boxed{B.18.610}[/tex]
Step-by-step explanation:
Hello There!
We can find y by using trigonometric ratios
sine, cosine and tangent
[tex]tan= \frac{opposite}{adjacent}[/tex]
the opposite of the angle that has a measure of 28 degrees is y and the side that is adjacent to the angle is 35
so...
[tex]tan28=\frac{y}{35}[/tex]
now we solve for y using basic algebra
we want to isolate the variable (y) using inverse operations
to get rid of the 35 we multiply each side by 35
[tex]\frac{y}{35} =y\\tan28*35=35tan28[/tex]
now we let the calculator do the rest of the work
[tex]35tan(28)=18.60983011[/tex]
*round to the nearest thousandth*
we're left with
y = 18.610
hence your answer is B

The height of the swipe card is given by :
[tex]h(t)=-3t^2+15t+18[/tex] .....(1)
We need to find the maximum height of the swipe card and the time to reach the maximum height.
For maximum height, put dh/dt = 0
So,
[tex]\dfrac{d}{dt}(-3t^2+15t+18)=0\\\\-9t+15=0\\\\t=\dfrac{15}{9}\\\\t=1.67\ s[/tex]
It will take 1.67 seconds to reach the maximum height.
Now, put t = 1.67 s in equation (1).
[tex]h(1.67)=-3(1.67)^2+15(1.67)+18\\\\=34.68\ feet[/tex]
Hence, the maximum height of the swipe card is 34.68 feet and the time to reach this height is 1.67 s.
