if radius equals 3 and the arc that bounds that sector is 40° what is the sector area and arc length equal?
Answer:
Sector area= 3.143 units²
Arc length = 2.095 units
Answer:
arc length = 3 * 40° * (PI / 180)
arc length = 2.0943951024
sector area = (radius * angle (radians))
sector area = (3 * 0.6981317008)
sector area = 3.1415926536

Step-by-step explanation:
What is the equation of the line that passes
through the point (-2,2) and the point (-6,4)?
Answer:
y = -1/2x+1
Step-by-step explanation:
First step is to find the slope
m = (y2-y1)/(x2-x1)
= ( 4-2)/(-6 - -2)
(4-2)/(-6+2)
2/-4
-1/2
Then we can use the slope intercept form of a line
y = mx+b where m is the slope and b is the y intercept
y = -1/2x+b
Substitute a point into the equation to find b
2 = -1/2(-2) +b
2 = 1+b
Subtract 1 from each side
1 =b
y = -1/2x+1
y = mx + b
Where m = slope and b is the y intercept
Let's find the slope = change in y/change in x
m = (4-2)/(-6+2) = 2/-4 = -1/2
Now we have:
y = (-1/2)x + b
Now substitute point (-6,4)
4 = (-1/2)(-6) + b
4 = 3 + b
b = 1
So y = (-1/2)x + 1 is the equation

nearest cent) TEKS A2.5(B)(D)
The total amount accrued, principal plus interest, with compound interest on a principal of $3,500.00 at a rate of 2.25% is $4,779.19.
Compound InterestGiven Data
Principal P= $3,500 Rate r = 2.25%Time t = 14 yearsFinal Amount A = ??A = P + I where
P (principal) = $3,500.00
I (interest) = $1,279.19
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 2.25/100
r = 0.0225 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 3,500.00(1 + 0.0225/1)^(1)(14)
A = 3,500.00(1 + 0.0225)^(14)
A = $4,779.19

x is an integer.
The Lowest Common Multiple (LCM) of x and 12 is 120
The Highest Common Factor (HCF) of x and 12 is 4
Work out the value of x
Since 120 = 12 • 10 and LCM(x, 12) = 120, these suggest x is some multiple of 10.
HCF(x, 12) = 4 tells us that x is a multiple of 4.
If x is a both a multiple of 4 and 10, then the smallest x that fits both conditions is 4 • 10 = 40. (-40 also satisfies the criteria.)
The value of x for which the LCM and HCF of x and 12 are 120 and 4 respectively is 40.
What do we mean by Lowest Common Multiple (LCM) and Highest Common Factor (HCF)?
The Lowest Common Multiple (LCM) of the numbers is the smallest common multiple of the given numbers.
The Highest Common Factor (HCF) of the numbers is the greatest factor of the given numbers.
In the case of two numbers, the product of LCM and HCF is equal to the product of the numbers.
How do we solve the given question?We are given two numbers, x and 12.
Their LCM and HCF are 120 and 4 respectively.
We are asked to find the number x.
For two numbers, we know that the product of two numbers is equal to the product of their HCF and LCM.
∴ x*12 = 120*4
or, 12x = 480
or, x = 480/12
or, x = 40.
∴ The value of x for which the LCM and HCF of x and 12 are 120 and 4 respectively is 40.

The length in units of the line segment A'B' in the resulting figure is the same as the length of line segment AB in the previous rectangle.
Translation of shapes in the Cartesian planeForm the task content;
It follows that the initial rectangle A is only translated and hence, the size of each of its sides remains constant.The translation which occurs on the rectangle only shifts the whole rectangle leftward and downward and hence, each line segment in the rectangle still retains its length.

Answer:
x = 85°
y = 45°
Step-by-step explanation:
For x, a line measures 180°, so subtract 95° from 180° to get 85°.
For y, all the angles in a triangle measure to 180°, and since we know x, add it to 50° and subtract it from 180°. 85° + 50° = 135°, and 180° - 135° = 45°
Answer:
x = 85
y = 45
Step-by-step explanation:
for x, angles on a straight line add up to 180 so 95 + x = 180 then evaluate for x
for y, angle in a triangle add up to 180 so 50+85 (as evaluated for x) +y= 180 and evaluate for y

Find the inverse of f(x)=5x-4.
The inverse of f is g(x)= ?
If g(x) is the inverse of f(x), then by definition of inverse function,
f(g(x)) = g(f(x)) = x
Given that f(x) = 5x - 4, we have
f(g(x)) = 5 g(x) - 4 = x
Solve for g(x) :
5 g(x) - 4 = x
5 g(x) = x + 4
g(x) = (x + 4)/5

Assume that 60% of the students at Remmington High studied for their Psychology test. Of those that studied, 25% got an A, but only 8% of those who didn't study got an A. What is the approximate probability that someone that gets an A actually studied for the Psychology test
The probability that someone that gets an A actually studied for the Psychology test is 0.15 or 15% if 60% of the students at Remmington High studied for their Psychology test. Of those that studied, 25% got an A, but only 8% of those who didn't study got an A.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Let A = the students get an A
Let B = the student's studied for the psychology test
We know that probability:
P(B) = 60% = 0.60 and
P(A/B) = 25% = 0.25
We know that:
[tex]\rm P(A/B) = \frac{P(A\cap B)}{P(B)} = 0.25[/tex]
Now the probability that someone that gets an A actually studied for the Psychology test:
P(A∩B) = P(B) ×0.25
P(A∩B) = 0.60×0.25
P(A∩B) = 0.15
Thus, the probability that someone that gets an A actually studied for the Psychology test is 0.15 if 60% of the students at Remmington High studied for their Psychology test. Of those that studied, 25% got an A, but only 8% of those who didn't study got an A.

If you borrow $700 for 5 years at
an annual interest rate of 7%, how
much will you pay altogether?
The amount you would pay altogether if you borrow $500 for 5 years at
an annual interest rate of 7% is $945.
How much would you pay altogether?The amount you would pay altogether is the sum of the amount borrowed and the interest.
Total value of the debt = interest + amount borrowed
Interest = $700 x 7% x 5 = $245
Total value of the debt = $245 + $700 = $945
