Answer:
∠1 = 81°
Step-by-step explanation:
∠1 and 81° are corresponding angles and corresponding angles are equal to each other.
The measure of ∠1 in the figure is 81°.
What are Angles?Angles are the figure formed by the intersection of two lines or rays by sharing a common point. This point is called the vertex of the angle.
Angles are usually measured in degrees or radians.
Given is a figure of two parallel lines which is cut by a transversal line.
There are many properties for the angles formed by the transversal lines.
One of the property is that corresponding angles are equal.
Corresponding angles are the pair of angles which are on the same side of each parallel lines and at the same side of the transversal but at different intersections.
In the given figure,
∠1 and 81°, ∠3 and ∠7, ∠2 and ∠6, ∠4 and ∠8 are corresponding angles.
Since ∠1 and 81° are corresponding angles ∠1 = 81°.
Hence, measure of angle 1 is 81 degrees.

Which represents the inverse of the function f(x) = 4x?
Oh(x) = x + 4
Oh(x) = x - 4
h(x) = x
Oh(x) = = x
Answers
Answer:
y = x/4
Step-by-step explanation:
First, replace f(x) with y, so it's easier to find the inverse:
y = 4x
To find the inverse of this function, you would replace all the y's with x's and all the x's with y's, and then solve for y. That would be:
x = 4y
y = x/4
Therefore, the inverse function of y = 4x is y = x/4.

What is the value of h(−2) when h(x)=3x+1?
Enter your answer in the box.
h(−2)=
Answers
Answer:
-5
Step-by-step explanation:
The answer is -5 because we have -2 as x. The function is h(x)=3x+1. 3 times -2=-6. When we add 1 to the result, we have -5 as the answer. Hope it helps!
The value of h(−2) when h(x)=3x+1 is h(-2) = -5
From the question,
The given function is h(x)=3x+1
To determine the value of h(-2), we will put x = -2 and evaluate
From
h(x)=3x+1
h(-2) becomes
h(-2)=3(-2) + 1
h(-2) = (3× -2) + 1
h(-2) = (-6) + 1
h(-2) = -6 + 1
h(-2) = -5
Hence, the value of h(−2) when h(x)=3x+1 is h(-2) = -5

Two pulleys, one with radius r 1r1 and the other with radius r 2r2, are connected by a belt. The pulley with radius r 1r1 rotates at omega 1ω1 revolutions per minute, whereas the pulley with radius r 2r2 rotates at omega 2ω2 revolutions per minute. Show that StartFraction r 1 Over r 2 EndFraction equals StartFraction omega 2 Over omega 1 EndFraction r1 r2
Answers
Answer:
r1/r2 = 2ω2/ω1
Step-by-step explanation:
The velocity of each pulley is expressed as v = ωr where;
v is the linear velocity of the pulley
ω is the angular velocity of the pulley
r is the radius of the pulley.
For the two pulleys, the velocity I'd both pulleys are the same.
v1 = v2
v1 is the linear velocity of first pulley
v2 is the linear velocity of the second pulley.
v1 = ω1r1
v2 = 2ω2(r2)
r1 and r2 is the radius of pulley 1 and pulley 2 respectively.
Since v1 = v2
ω1r1 = 2ω2(r2)
Divide both sides by r2
ω1r1/r2 = 2ω2(r2)/r2
ω1r1/r2 = 2ω2
Divide both sides by ω1
ω1r1/r2/ω1= 2ω2/ω1
r1/r2 = 2ω2/ω1

An angle is 36⁰ less than its complement. What is the measure of the angle?
Answers
Answer:
27 degrees.
Step-by-step explanation:
If the angles are x and y then as they are complementary:
x + y = 90 - and we are given that:
x - y = 36 Adding the 2 equations:
2x = 126
x = 63.
So 63 - y = 36
y = 63 - 36 = 27.

An umbrella at a shop was marked for $6 . During a sale, a discount of 10% was given. A further 8% discount was given to the senior citizens. How much would a senior citizen need to pay for the umbrella during the sale? Round your answer to the nearest cent.
Answers
Answer:
A senior citizen will pay $4.97
Step-by-step explanation:
Mathematically, discount = discount percentage * marked price
Sales price = marked price - discount
In the question, marked price = $6
First, we have a discount of 10%, so therefore , the sales price will be;
$6 - (10/100 * $6 ) = $6 - $0.6 = $5.4
Now, a further 8% discount was given to senior citizens,
The extra discount for senior citizens is thus;
8/100 * 5.4 = $0.432
Amount to be paid by senior citizens = $5.4 - $0.432 = $4.968. which is $4.97 to the nearest cent
Answer:
the answer is $4.97.
