Write the equation of a line that is perpendicular to Y= 4 and that passes through (7,2)
Answer:
x = 7
Step-by-step explanation:
y = 4 is a horizontal line that passes through the point (0, 4).
A line perpendicular to y = 4 is a vertical line.
In a vertical line, all points have the same x-coordinate.
Since the point (7, 2) is on the vertical line we want, and its x-coordinate is 7, then x-coordinate of all the points on the line we want is 7.
Answer: x = 7
What is the measure of the third angle of a triangle if one angle measures 35 degrees and the second angle measures 40 degrees?
Step-by-step explanation: It's important to understand that the sum of the measures of the interior angles of a triangle is always 180 degrees.
So let's first add up the measures of the two angles we know.
So we have 30 + 4 which is 75 degrees.
The missing angle will be equal to 180 minus 75.
So the missing angle measure is 105 degrees.
Consider a square whose sides are of length x. Draw the largest circle that is completely contained within the square. Find the area of the region that is inside the square and but not inside the circle. Express your answer in terms of x and any other mathematical constants that may be necessary.
Answer:
A₁ = x²* ( 1 - π /2) square units
Step-by-step explanation:
Let´s call the area of the region that is inside the square but not inside the circle A₁
And the area of the square A(s)
And the area of the circle A(c)
Then the area we are looking for is:
A₁ = A(s) - A(c)
If the circle has a radius r then
A(c) = π*r²
A(s) = x²
In the square diagonal of the square is d = √ x² + x² ; d = √2 * x
Half of this distance is d/2 = (√2 /2)*x
There is a right triangle with points:
o The center of the square (which is the center of the circle)
a Any of the corners of the square
b Middle point of a side of the square
According to that
r the radius of the circle is:
r² + (x/2)² = (d/2)²
r² + (x/2)² = [ (√2 /2)*x]²
r² = (2/4)*x² - x²/4
r² = (x²/2) - x² / 4
r² = (1/2)*x²
r = x/√2
Then the area of the circle is
A(c) = π * r²
A(c) = π * x²/2
And A₁ = x² - π * x²/2
A₁ = x²* ( 1 - π /2) square units or A₁ =[ ( 2 - π)/2 ]*x²
What expression is equivalent to this equation?

Answer:
C
Step-by-step explanation:
If m∠ABD = 100 and m∠DBC = 30, then m∠ABC=?
The measure of angle ABC is 130 degrees
How to determine the measure of ABC?The angles are given as
ABD = 100
DBC = 30
The measure of angle ABC is calculated using
ABC = ABD + DBC
So, we have
ABC = 100 + 30
Evaluate the sum
ABC = 130
Hence, the measure of angle ABC is 130 degrees

A fruit stand has to decide what to charge for their produce. They need $5.30 for 1 apple and 1 orange.
They also need $7.30 for 1 apple and 2 oranges. We put this information into a system of linear equations,
Answer:
The price of Apples is $3.30 and the price of Oranges is $2.
Step-by-step explanation:
So first treat the price of apples and the price of oranges as variables. Let's say that the price of an apple is X and the price of an orange is Y.
1 Apple and 1 Orange is $5.30, so the equation is 1X + 1Y = 5.30
1 Apple and 2 Oranges is 7.30 so the equation is 1X + 2Y = 7.30
Now, adjust one of the equations so you can know the price of one thing in relation to the price of the other.
1X + 1Y = 5.30 can become 1X = 5.30 - 1Y
Now substitute this into the other equation.
1X + 2Y = 7.30 becomes 5.30 - 1Y + 2Y = 7.30. Now, either combine the Y values or combine the price values.
5.30 + 1Y = 7.30
Y = $2
Now that you have the Y value, replace it in one of the equations.
1X + 2$ = 5.30
1X = 3.30

Fill in the missing number to complete the linear equation that gives the rule for this table. Explain/show how you got your answer in
as much detail as you can.
Answer:
y = x - 1
Step-by-step explanation:
To create a linear equation in the slope-intercept form, which is in the form of y = mx + b, we need to find the slope/rate of change, m, and the y-intercept, b.
Rate of change can be calculated using two pairs, (3, 2) and (4, 3)
Rate of change/slope (m) = [tex] \frac{f(b) - f(a)}{b - a} [/tex],
Where,
b = 4
f(b) = 3
a = 3
f(a) = 2
Plug in the values
[tex] \frac{3 - 2}{4 - 3} = \frac{1}{1} [/tex]
m = 1
Plug in x = 3, y = 2 and m = 1 into y = mx + b
2 = 1(3) + b
Solve for b
2 = 3 + b
Subtract 3 from each side
2 - 3 = b
-1 = b
b = -1
Substitute m = 1 and b = -1 into y = mx + b.
y = 1(x) +(-1)
y = x - 1
The linear equation that gives the rule for this table is y = x - 1

Step-by-step explanation:
What is the quotient of 2 1/5÷6 3/5 in simplest form?
Answer:
The quotient for the problem 2 1/5÷6 3/5 in simplest form is 1/3.
write the product as a sum: 14cos(39x)sin(19x)
Recall that
sin(a + b) = sin(a) cos(b) + cos(a) sin(b)
sin(a - b) = sin(a) cos(b) - cos(a) sin(b)
Adding these together gives
sin(a + b) + sin(a - b) = 2 sin(a) cos(b)
To get 14 cos(39x) sin(19x) on the right side, multiply both sides by 7 and replace a = 19x and b = 39x :
7 (sin(19x + 39x) + sin(19x - 39x)) = 14 cos(39x) sin(19x)
7 (sin(58x) + sin(-20x)) = 14 cos(39x) sin(19x)
7 (sin(58x) - sin(20x)) = 14 cos(39x) sin(19x)

What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.
Given,
In triangle ACD and CAB, AB || CD and AC ≅ BD.
Therefore, The triangles ACD and CAB are congruent by ASA as ∠A is congruent to ∠C, Side AB is congruent to side CD and ∠B is congruent to ∠B.

Answer:
y = -x-6
Step-by-step explanation:
For this problem we use point-slope formula:
y-y1 = m (x2-x1)

The table below shows the commission for selling cameras in a
shop for one month.
For the first 20 cameras
$150 total
For every additional camera
$15 per camera
John received a $1,110 commission by selling cameras last
month. How many cameras did he sell last month?
cameras
Answer:
84
Step-by-step explanation:
You first do 1,110-150= 960 dollars.
Then you divide 960 by 15 dollars = 64 cameras
So the first 20 cameras plus the 64 cameras equal 84 cameras.
Which of the following statements best describes the end of the decimal conversation of a rational number
Answer:
Any rational number (that is, a fraction in lowest terms) can be written as either a terminating decimal or a repeating decimal . Just divide the numerator by the denominator . If you end up with a remainder of 0 , then you have a terminating decimal.
Step-by-step explanation:
Convert the fraction 7/12
to a decimal.
7/12=0.583¯
This is a repeating decimal.
