Answer:
w=6
l=14
Step-by-step explanation:
Area of rectangle = l*w
So:
[tex]w*(w+8)=84[/tex]
Then, just find w, and w+8.
[tex]w^2+8w=84\\w^2+8w-84=0\\(w-6)(w+14)=0\\w-6=0, w=6\\w+14=0, w=-14[/tex]
Length cannot be negative, so the width is 6.
Length = width + 8 = 6+8=14

What is mid point theorem?The mid point theorem states that in a triangle the line segment joining the mid point of two sides is always parallel and equal to half of the length of the third side.
As per the given figure the data is as follows,
The line segment of length 6x + 7 is parallel to the side of a triangle of length 19x - 28 such that it divides other two sides equally.
Apply mid point theorem to obtain,
6x + 7 = 1/2(19x - 28)
=> 19x/2 - 6x = 14 - 7
=> 7x/2 = 7
=> x = 2
Hence, the value of x for the given triangle is 2.

Step-by-step explanation:
Write the linear equation that gives the rule for this table.
Answer:
f(x) = -7x + 1
Step-by-step explanation:
Slope intercept form is
y = mx + b
m is slope
b is y-intercept
--------------------------
y decreases by 7 for each increase of 1 in x
slope = -7
to find "b" plug in one of the points and m = -7
using point (3, -20)
y = mx + b
-20 = -7(3) + b
-20 = -21 + b
b = 1
The equation is
f(x) = -7x + 1

13. Car Depot rents a car for an initial fee of $20
plus an additional $0.10 per mile. Model the
total cost of the rental car C as a function of the
number of miles driven m.
a
a. C(m) = .10(20m)
b. C(m) = m(20+.10)
C. C(m) = 20m +.10
d. C(m) = .10m + 20
2
Answer:
d. C(m) = .10m + 20
Step-by-step explanation:
Given the following data;
Initial rent fee = $20
Cost per mile = $0.10
To find the total cost;
The total cost is simply the sum of the initial rent fee and the cost per mile of the car.
Mathematically, the total cost is given by the expression;
T = I + cm
Substituting into the above formula, we have;
T = $20 + 0.10m
In parallelogram ABCDwith diagonals AC and BD, which of the following is true?
Answer:
Last one at the bottom
Step-by-step explanation:
Because all of those diagonals are equal to each other. So that would mean those diagonals are equal in legnth.
BD is perpendicular to AC Because; all of those diagonals are equal to each other that would mean those diagonals are equal in length.
What is a parallelogram?That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
Remember that the parallelogram in which adjacent sides are perpendicular to each other is called a rectangle.
The diagonals of the parallelogram are perpendicular to each other and they cut each other in half( thus, they're perpendicular bisector of each other).
BD is perpendicular to AC Because; all of those diagonals are equal to each other that would mean those diagonals are equal in length.

A=P(1+)
"
Sant Pere
Answer:
The person must leave the money for 11.8 years until the investment reaches 1600 dollars.
Step-by-step explanation:
Given that a person invests 1000 dollars in a bank, and the bank pays 4% interest compounded quarterly, to determine to the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 1600 dollars the following calculation must be done:
1000 x (1 + 0.04 / 4) ^ Xx4 = 1600
1000 x 1.01 ^ 4X = 1600
1010 ^ 4X = 1600
X = 11.8
Therefore, the person must leave the money for 11.8 years until the investment reaches 1600 dollars.

5 + 14xy = 9xy - 5
=> First subtract 9xy from each side of "="
5 + 5xy = -5
=> Now, subtract 5 from each side:
5xy = -10
=> Finally divide 5 on each side:
xy = -10/5
xy = -2

Convert the polar representation of this complex number into its rectangular
form:
z = 4(cos pi/2 + i sin pi/2)
Please help!!! I will mark brainliest!!! Thank you!!!
Answer: (0,4)
Step-by-step explanation:
The complex number z = 4 into its rectangular form
What is complex number?Every complex number may be represented in the form a + bi, where a and b are real numbers. A complex number is an element of a number system that extends the real numbers with a specific element labeled I sometimes known as the imaginary unit, and satisfying the equation i² = 1.
Given
* Lets revise the complex numbers
- If z = r(cos Ф ± i sin Ф), where r cos Ф is the real part and i r sin Ф is the imaginary part in the polar form
- The value of i = √(-1) ⇒ imaginary number
- Then z = a + bi , where a is the real part and bi is the imaginary part
in the rectangular form
∴ a = r cos Ф and b = r sin Ф
* Lets solve the problem
∵ z = r (cos Ф ± i sin Ф)
∵ z = 4 (cos π/2 + i sin π/2)
∴ The real part is 4 cos π/2
∴ The imaginary part is 4 sin π/2
- Lets find the values of cos π/2 and sin π/2
∵ The angle of measure π is on the positive part of x axis at the
point (0 , 4)
∵ x = cos π/2 and y = sin π/2
∴ cos π/2 = 0
∴ sin π/2 = 1
∴ a = 4(0) = 0
∴ b = 4(1) = 4
∴ z = 0 + i (4)
* The complex number z = (0,4) into its rectangular form

Answer:
Binomial probability distribution concept & application, example
Step-by-step explanation:
Yes, this represents a binomial setting. As, it is used for finding probability of - particular number of success outcomes , from repetitive or multiple events.
Here
Success {Event P} ie small fish, with prob = 30% = 0.3 .Failure {Event Q} ie large fish, with prob = 70% = 0.7Number of trials = 20. Let r be number of small fishes out of 20 fishes.Binomial probability = N c r . (P)^r . (Q)^ (n-r)

Haley is going on a vacation to Australia. Her flight leaves at 10:20 A.M. It takes 1 hour and
20 minutes to get to the airport, and Haley wants to be at the airport 55 minutes before her
flight leaves. What is the latest time that Haley can leave for the airport?
HELPPPPP FACTUAL ANSWERS
Answer:
8:05 am is the time she will have to leave her house to get to the airport on time.
Step-by-step explanation:
First, subtract 55 minutes from 10:20.
10:20 - 20 = 10:00
10:00 - 35 = 9:25
This is the time she wants to arrive. 9:25
Now, we have to subtract an hour and 20 minutes
9:25 - 1:00 = 8:25
8:25 - 20 = 8:05

Step-by-step explanation: Please find the attached image of unit circle.
We have been given that the measure of angle t is 60 degrees. We are asked to find the x-coordinate of the point where the terminal side intersects the unit circle.
We know that x-coordinate on unit circle represents cosine and y-coordinate represents sine of a given angle.
We can see from our attachment that x-coordinate of the point at angle 60 degrees is , therefore, x-coordinate of the angle of 60 degrees, where the terminal side intersects the unit circle is .
