One container of fertilizer covers 900 square feet. A property has a rectangular backyard that is 30 feet long and 20
feet wide. The front yard is triangular with a base of 24 feet and a height of 12 feet. What percentage of the container
will be used on the property? Round to the nearest percentage.
Answers
Answer:
82.67% of the fertilizer will be used on the property.
Step-by-step explanation:
Area of Plane Figures
The backyard described in the problem has two parts: One with a rectangular shape of 30 feet by 20 feet. The other with a triangular shape with a base of 24 feet and a height of 12 feet.
The area of a rectangle is calculated by:
[tex]A_r=L*W[/tex]
And the area of a triangle is:
[tex]\displaystyle A_t=\frac{B*H}{2}[/tex]
All the backyard will be covered by fertilizer coming from a container with a capacity of 900 square feet.
The total area of the backyard is the sum of the area of the rectangle Ar and the area of the triangle At as follows:
[tex]A_r=30*20=600\ ft^2[/tex]
[tex]\displaystyle A_t=\frac{24*12}{2}=144\ ft^2[/tex]
The total area of the backyard is:
[tex]A=600\ ft^2+144\ ft^2=744\ ft^2[/tex]
To find the percentage of the container, we calculate:
[tex]\displaystyle \frac{744}{900}*100\%=82.67\%[/tex]
82.67% of the fertilizer will be used on the property.

Find the equation of the line parallel to y = -1/2 - 4 and goes through the point (-2,-5)
Answers
Answer:
The equation of the line is y = - 1/2 x - 6
Step-by-step explanation:
The equations of parallel lines have the same slopes and different y-intercepts
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept (value y at x = 0)To find b substitute x and y in the equation by the coordinates of a point on the line∵ The given equation is y = -1/2 x - 4
→ By comparing it by the form of the equation above
∴ m = -1/2
∵ Parallel lines have the same slope
∴ The slope of the line = -1/2
→ Substitute it in the form of the equation above
∴ y = - 1/2 x + b
∵ The line passes through the point (-2, -5)
→ To find b substitute x by -2 and y by -5
∴ -5 = -1/2 (-2) + b
∴ -5 = 1 + b
→ Subtract 1 from both sides
∴ -5 - 1 = 1 - 1 + b
∴ -6 = b
→ Substitute the value of b in the equation above
∴ y = - 1/2 x + (-6)
∴ y = - 1/2 x - 6
The equation of the line is y = - 1/2 x - 6

Solve algebraically for all the values of x -2x^5+14x^4-2x^3+14x^2=0
Answers
Answer:
0, 7, ± iStep-by-step explanation:
Solving for x
- 2x^5 + 14x^4 - 2x^3 + 14x^2=0x^5 - 7x^4 + x^3 - 7x^2 = 0x^2 ( x^3 - 7x^2 + x - 7) = 0x^2( x^2(x - 7) + (x - 7)) = 0x^2(x^2 + 1)(x - 7) = 0x^2 = 0 ⇒ x = 0x^2 + 1 = 0 ⇒ x^2 = -1 ⇒ x = ± ix - 7 = 0 ⇒ x = 7The solutions to the original equation -2x³ + 14x²- 2x³ + 14x² = 0 are x = 0, -0.391, 0.099, 7.293
To solve the equation algebraically, factor out an "x^2" term from each term:
x²(-2x³ + 14x²- 2x + 14) = 0
Now, we have two factors:
x² = 0
-2x³ + 14x² - 2x + 14 = 0
First, let's solve the first factor, which is a simple quadratic equation:
x² = 0
x = 0
Now, let's solve the second factor by factoring out a common factor of 2:
2(-x³ + 7x² - x + 7) = 0
Now,use the rational root theorem or synthetic division to find the roots of the cubic equation -x³ + 7x² - x + 7 = 0. However, in this case, the equation does not have any rational roots. Therefore, we need to use numerical methods or graphing techniques to find the approximate solutions.
Using numerical methods or graphing, we find that the approximate solutions for the equation -x³ + 7x² - x + 7 = 0 are:
x ≈ -0.391
x ≈ 0.099
x ≈ 7.293

The initial Velocity of that object would be zero.
What is initial velocity?Initial Velocity, denoted as u, is the velocity at time period t = 0. It is the speed at which motion first occurs. When gravity first exerts a force on an object, its initial velocity defines how quickly the object moves.
They are three initial velocity formulas:
(1) If time, acceleration, and final velocity are provided, the initial velocity is articulated as u = v – at
(2) If final velocity, acceleration, and distance are provided we make use of u² = v² – 2 as
(3) If distance, acceleration, and time are provided, the initial velocity is
s = ut + 1/2at²
Where,
Initial velocity = u,
Final Velocity = v,
time taken = t,
distance travelled or displacement = s,
acceleration = a
From the third formula of velocity
s = ut + 1/2at²
If u = 0
then s = 1/2at²
=> at² = 2s
=> t² = 2s/a
=>t = [tex]\sqrt{2\frac{s}{a} }[/tex]
Which is the same as the given equation
therefore, That object's initial velocity would be zero.
