Answer:
the width of the rectangle is -5/3 inches.
Step-by-step explanation:
To find the perimeter of the rectangle, we add together the lengths of all four sides. Since the rectangle is 5 inches long and 2x inches wide, the perimeter is given by:
Perimeter = 5 + 2x + 5 + 2x = 10 + 4x
To find the area of the rectangle, we multiply the length by the width. The area is given by:
Area = 5 * 2x = 10x
Setting the perimeter equal to the area, we have:
10 + 4x = 10x
Subtracting 10 from both sides, we have:
4x = 10x - 10
Combining like terms, we have:
-6x = -10
Dividing both sides by -6, we have:
x = 10 / -6
Simplifying, we have:
x = -5/3

find the zeros f(x) = x 3 - 3x 2 – 5x +15
Answer:
x = ± [tex]\sqrt{5}[/tex] x = 3
Step-by-step explanation:
to find the zeros set f(x) = 0 , that is
x³ - 3x² - 5x + 15 = 0 ( factor the first/second and third/fourth terms )
x²(x - 3) - 5(x - 3) = 0 ← factor out (x - 3) from each term
(x - 3)(x² - 5) = 0
equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x² - 5 = 0 ( add 5 to both sides )
x² = 5 ( take square root of both sides )
x = ± [tex]\sqrt{5}[/tex]
the zeros of f(x) are then
x = - [tex]\sqrt{5}[/tex] , x = [tex]\sqrt{5}[/tex] , x = 3

The account balance of Bob Rowinski if he kept the money on deposit for 6 months is $4,032.00.
What is Bob Rowinski account balance the interest payment is made?The compound interest formula can be expressed as;
A = P(1 + r/n)^(n*t)
Where A is accrued amount, P is principal, r is interest rate, t is time elapsed.
Given the data in the question;

A = P(1 + r/n)^(n*t)
A = $4000( 1 + 0.016/2 )^(2*0.5)
A = $4000( 1 + 0.008 )^(1)
A = $4000( 1.008 )
A = $4,032.00
Therefore, the accrued amount after half a year is $4,032.00

"Use the formula A=P(1+r/n)ⁿt to solve the compound interest problem
Find how long it takes for $ 900 to double if it is invested at 6 % interest compounded monthly.
The money will double in value in approximately years."
After 11.61 years the given principal amount of $ 900 will be double.
What is Compound interest?
Compound interest is interest charged on a loan and is determined by both the principal amount and the rate of interest compounding per year.
The formula for the Amount when compound interest is calculated is given by
Amount, A = P(1+r/n)^nt
P = Principal amount
r = Rate of interest
n = Number of compounds
t = Time period in years
Given:
Principal amount = $ 900
Rate of interest = 6% = 6/100 = 0.06
Number of compounds = 12 [ ∵ compounded monthly]
We need to find the time period
Assume that after 't' years the amount will be doubled
From the given data and formula,
Amount, A = 900(1+0.06/12)^12t
= 900(1+0.06/12)^12t
= 900(1 + 0.005)^12t
= 900 (1.005)^12t
As we assumed after 't' years the amount is double
=> 900 (1.005)^12t = 2 × 900
=> (1.005)^12t = 2
Applying log on both sides
=> log (1.005)^12t = log 2
=> 12t log(1.005) = log 2
=> 12t = log 2/log(1.005)
=> 12t = 0.30108/ 0.00216
=> 12t = 139.888
=> t = 11.61
Hence, after 11.61 years the given principal amount of $900 will be double.

Answer:
1. x-intercept = (1, 0), y-intercept = (0, -2)
7. y + 4 = -6( x - 7)
Step-by-step explanation:
Question 1Given point-slope equation:
[tex]y-2=2(x-2)[/tex]
The x-intercept is when y = 0:
[tex]\begin{aligned}y=0\implies 0-2 &=2(x-2)\\-2&=2x-4\\2&=2x\\x&=1\end{aligned}[/tex]
The y-intercept is when x = 0:
[tex]\begin{aligned}x=0\implies y-2 &=2(0-2)\\y-2&=2(-2)\\y-2&=-4\\y&=-2\end{aligned}[/tex]
Therefore, the intercepts are:
x-intercept = (1, 0)y-intercept = (0, -2)To graph the equation, plot the intercepts and draw a straight line through them. (See attachment 1).

Given:
m = -6(x₁, y₁) = (7, -4)Substitute the given slope and point (7, -4) into the formula to write the equation of the line in point-slope form:
[tex]\implies y-(-4)=-6(x-7)[/tex]
[tex]\implies y+4=-6(x-7)[/tex]
To graph the line, find the value of y when x = 6 and when x = 8:

B. The milkweed population is an abiotic factor that decreased as the amount of sunlight, a biotic factor, decreased.
C. The milkweed population is a biotic factor that decreased as the amount of sunlight, an abiotic factor, increased.
D. The milkweed population is an abiotic factor that decreased as the amount of sunlight, a biotic factor, increased.
Option A is correct.
What is increasing and decreasing graphs?
Generally speaking, we are aware that if something is growing, it is moving upward, and if it is shrinking, it is moving downward. As a result, if we talk about a function's graph, an increasing function is one that is moving upward, and a decreasing function is one that is moving downward.
From the graph, we infer that the sunlight, that is the shaded area increased in the given time. Which means that the sunlight was less.
From the milkweed population graph, we see that the milkweed population decreased over time.
Hence the most supportive hypothesis would be option A.
The milkweed population is a biotic factor that decreased as the amount of sunlight, an abiotic factor, decreases.

A + k/2 = -2 (2)
Subtract 1 - 2 as

The length AE of the rhombus is √195 units
How to determine the length AE of the rhombus?From the question, we have the following parameters that can be used in our computation:
AD = 4x + 2
DC = 7x - 13
BD = 34
All the four sides of a rhombus are congruent
This means that
DC = AD
Substitute the known values in the above equation, so, we have the following representation
7x - 13 = 4x + 2
Evaluate the like terms
3x = 15
Divide both sides by 3
x = 5
Substitute x = 5 in AD = 4x + 2
So, we have
AD = 4 x 5 + 2
AD = 22
The length AE of the rhombus is then calculated as
AE² = AD² - (BD/2)²
Substitute the known values in the above equation, so, we have the following representation
AE² = 22² - (34/2)²
Evaluate
AE² = 195
Take the square roots

We have to find the most general antiderivative of the function on the interval (-π/2, π/2).
We know that,
Take the function,
f(x)=7sinx -4secx tanx.
The antiderivative is

What is an equivalent fraction ?
According to equivalent fractions, two or more fractions are considered to be equal if, following simplification, both provide the same fraction. Let's imagine that a/b and c/d are two fractions. If these fractions are simplified to produce comparable fractions, such as e/f, they are then equal to one another.
For instance, if we simplify 5/15, the resulting fraction is the same as 1/3, hence that is the equivalent fraction of 1/3.
The fractions with distinct numerators and denominators but the same value are said to be equivalent fractions. For instance, since 2/4 and 3/6 both equal the 12, they are identical fractions. An element of a whole is a fraction. The same amount of the whole is represented by equivalent fractions.
As in the given model 2 out of 5 blocks are in red color which means the equivalent fraction to the given model is 2/5 which is equal to 4/10
