Answer:
Step-by-step explanation:
Circle - A = πr²
Semi circle - A= 1/2 πr²
Trapezoid - A= 1/2 (base 1 + base 2 ) x height
Rectangle - length x width
Triangle - A= 1/2 base x height
Answer:
(see below)
Step-by-step explanation:
A) Trapezoid
3. A = 1/2 (base 1 + base 2 ) x height
~
B) Circle
1. A = πr²
~
C) Rectangle
5. A = length x width
~
D) Semicircle
4. A = 1/2 πr²
This is half of a circle, so it would be 1/2 of the area of a circle, hence the 1/2.
~
E) Triangle
2. A = 1/2 base x height
If you cut a rectangle in half diagonally, you have two triangles. So it's half the area of a rectangle. This is one way to think about it, hence the 1/2.
Rosanne and Jimmy are looking to purchase a house. They found one that they like, but the inspection report showed that there was a problem. The foundation has termites. The report states that the foundation of a house has 1200 termites. The termites grow at a rate of about 2.4% each day. A. Formulate an equation in exponential form that represents the termite situation. (5 points) B. The extermination is scheduled out for one week from the date of the report. Use your equation to determine how many termites will be in the home at the time of the extermination. (5 points)
Answer:
A.P(t) = Po (1 + r)^t
P(t) = 1200( 1 + 0.024)^t
B. 1417 termites
Step-by-step explanation:
Rosanne and Jimmy are looking to purchase a house. They found one that they like, but the inspection report showed that there was a problem. The foundation has termites. The report states that the foundation of a house has 1200 termites. The termites grow at a rate of about 2.4% each day.
A. Formulate an equation in exponential form that represents the termite situation.
The formula for exponential growth or increase =
P(t) = Po (1 + r)^t
Where:
P(t) = Population growth after time t
P(o) = Initial Population = 1200 termites
r = Growth rate = 2.4% = 0.024
t = Time in days
Hence, the equation in exponential form that represents the termite situation is given as:
P(t) = 1200( 1 + 0.024)^t
B. The extermination is scheduled out for one week from the date of the report. Use your equation to determine how many termites will be in the home at the time of the extermination.
The time of extermination = 1 week
1 week = 7 days
Hence,
t = 7 days
P(t) = Po (1 + r)^t
P(7) = 1200( 1 + 0.024)⁷
P(7) = 1200(1.024)⁷
P(7) = 1416.7099449 termites
Approximately
= 1417 termites

Consider the function represented by 9x+3y= 12 with x as the independent variable. How can this function be written
using function notation?
flv -v+
f(x) = - 3x + 4
f(x) = - *x+
f(V) = - 3y + 4
Answer:
b) y = f(x) = -3x+4
Step-by-step explanation:
Explanation
Given that the equation 9x+3y =12
Let 'x' be an independent variable and 'y' be the dependent variable then the function is of the form
y = f(x)
3 y = 12 - 9x
[tex]y = \frac{-9x+12}{3}[/tex]
y = -3x+4
The function represented by y = -3x+4

A car is purchased for 32,000. The value of the car depreciates by 3% per year.
A. Write an exponential function to model the value of the car after t years?
B. What is the value of the car 6 years after it is purchased?
Answer:
A) car one is linear because it decreases the same amount every year.
car two decreases by the same ratio so it's exponential.
B) for car one y = -6,000x + 38,000 (y is the value after x years, -6,000 is what it changes by every year, and 38,000 is the amount of year 0)
for car two y = (44,000) (17/20)x-1 (y is the value after x years, 44,000 is the amount on year 0, and 17/20 is the ratio)
C) after 5 years car one will be 8,000
after 5 years car two will be about 16,860

Answer:
15.5 meters of wood.
Step-by-step explanation:
Find the perimeter of the box.
2(1.50)+2(6.25)=15.5
Answer:
15.5 m of wood
Step-by-step explanation:
The perimeter of this 1.5 m by 6.25 m frame is a measure of the length of wood needed. Here P = 2(1.5 m) + 2(6.25 m) = 3 m + 12.5 m, or 15.5 m

A poster has a rectangular printed area 100 cm by 140 cm and a blank strip of uniform width around the edges. The perimeter of the poster is 1 2 3 times the perimeter of the printed area. What is the width of the blank strip
Answer:
90 cm
Step-by-step explanation:
Given that :
Perimeter of a rectangle = 2(Length + Width)
Perimeter of print area = 2(100 + 140) = 480cm
Perimeter of entire poster :
Let uniform width of blank strip = x
x on each of the 4 sides side ;
2(2x + 100 + 2x + 140)
2(4x + 240)
8x + 480
Perimeter of poster = 1 2/3 perimeter of print area
8x + 480 = 5/2(480)
8x + 480 = 1200
8x = 1200 - 480
8x = 720
x =. 720 / 8
x = 90 cm

Denzel wants to work out the density of a block of wood the block of wood is in the shape of the cuboid
Answer:
[tex]Density = 1.094g/cm^3[/tex]
Step-by-step explanation:
Given
[tex]Length = 17.7cm[/tex]
[tex]Width = 8.3cm[/tex]
[tex]Height = 13.0cm[/tex]
[tex]Mass = 2090g[/tex]
See attachment
Required
Determine the density of the wood
First, we calculate the volume of the wood.
[tex]Volume = Length * Width * Height[/tex]
Substitute values for Length, Width and Height
[tex]Volume = 17.7cm * 8.3cm * 13.0cm[/tex]
[tex]Volume = 1909.83cm^3[/tex]
The density is:
[tex]Density = \frac{Mass}{Volume}[/tex]
[tex]Density = \frac{2090g}{1909.83cm^3}[/tex]
[tex]Density = 1.094g/cm^3[/tex] --- approximated

If f(x) = x², then f(2 – 3i) equals
A. -5
B. -5 – 12i
C. 13 – 12i
D. 13
Answer:
A
Step-by-step explanation:
f(2 – 3i) = (2 – 3i)^2
f(2 – 3i) = (2)^2 + (-3i)^2
f(2 – 3i) = 4 + (9)(-1)
f(2 – 3i) = 4 - 9
f(2 – 3i) = -5
These are functions in another function. The result of the function f(2-3i) is -5-12i
Composite functionsThese are functions in another function. Given the function shown below;
f(x) = x²
In order to determine f(2 – 3i), you will replace as 2 - 3i to have:
f(2 - 3i) = (2 - 3i)²
Expand
f(2 - 3i) = 2² - 12i + 9i²
f(2 - 3i) =4 - 12i - 9
f(2 - 3i) = -5-12i
Hence the result of the function f(2-3i) is -5-12i

if the simple interest on $5000 for 5 years is $1500 then what is the interest rate?
Answer:
6%
Step-by-step explanation:
Simple interest: A = P(1 + rt)
Solve for r: r = (1/t)((A/P) - 1)
Given:
A = $1500 + $5000 = $6500
P = $5000
t = 5 yrs
r = (1/5)((6500/5000) - 1)
= (1/5)(0.3)
= 0.06
0.06 = 6%

Answer:
NO
Step-by-step explanation:
It is a right triangle if the thee sides satisfy the following pythagorean triple rule/theorem, c² = a² + b², where,
c is the longest side = 50
a = 15
b = 49
Let's check:
50² = 15² + 49²
2500 = 2626 (this is not true).
Therefore, the triangle is not a right triangle. The answer is NO.
