Step-by-step explanation:
Step 1:
y = mx + b Slope Intercept Form
Step 2:
y = 3/5x + b Input Slope
Step 3:
- 2 = 3/5 ( 0 ) + b Input x and y
Step 4:
- 2 = 0 + b Multiply
Step 5:
- 2 = b
Answer:
y = 3/5x - 2
Hope This Helps :)
The equation of the line in slope-intercept form is y = (3/5)x - 2.
To find the equation of the line in slope-intercept form (y = mx + b), where 'm' is the slope and 'b' is the y-intercept, we are given the slope (3/5) and a point on the line (0, -2).
Step 1: Use the point-slope form of the equation:
y - y₁ = m(x - x₁)
where (x₁, y₁) is the given point (0, -2) and 'm' is the slope (3/5).
Step 2: Substitute the values:
y - (-2) = (3/5)(x - 0)
Step 3: Simplify:
y + 2 = (3/5)x
Step 4: Isolate 'y' by subtracting 2 from both sides:
y = (3/5)x - 2
Now, we have the equation of the line in slope-intercept form:
y = (3/5)x - 2

A traffic helicopter descends 107 meters to be 407 meters above the ground, as illustrated in the diagram to the right. Write an equation to describe the situation using h as the original height of the helicopter. What was the original height of the helicopter?
Step-by-step explanation:
Its 514 because 107+407 is 514
Answer:
h = 514 meters
Step-by-step explanation:
If the helicopter descends 107 meters to then be 407 meters above the ground, then it was originally 107 meters above 407 meters.
h-107=407
add 107 to both sides
h = 107+407
h = 514
estimate the area of the circle. use 3.14 3.14 or 22 7 227 for π π.
Answer:
615.44
Step-by-step explanation:
If the diameter is 28, that means the radius is 14.
The formula for the area of a circle is pi x radius to the power of 2. So, 14 to the power of 2 (or 14 x 14) equals 196. 196 x 3.14 (pi) = 615.44
The estimated area of the circle is about 615.44 cm² or 616 cm², depending on which value you use for π.
How to find the area of a circle?Suppose the circle has radius of 'r' units, then, its area is given as:
[tex]A = \pi \times r^2[/tex] sq. units
Since radius of a circle is half of its diameter, so if diameter is of 'd' length, then r= d/2, thus, area can be rewritten as:
[tex]\pi \times (\dfrac{d}{2})^2[/tex] sq. units
We are given that;
Diameter=28cm
Now,
In this case, the diameter of the circle is 28 cm, so the radius is half of that:
r = 28 / 2 = 14 cm
Plugging this value into the formula, we get:
A = π × 14²
Now we can use either 3.14 or 22/7 for π. Let’s use both and compare:
A ≈ 3.14 × 14² ≈ 3.14 × 196 ≈ 615.44 cm²
Or
A ≈ (22/7) × 14² ≈ (22/7) × 196 ≈ (4312/7) cm² ≈ 616 cm²
Therefore, by the area of circle the answer will be 615.44 cm² or 616 cm², depending on which value you use for π.

Write an expression for the area of a square with sides of length a + b.
Use the distributive property to fully expand the expression.
Show your work.
Area
Answer:
area = (a + b)² = a² + 2ab + b²
Step-by-step explanation:
let side length = a + b
area of a square = side length × side length
⇒ area = (a + b)²
= (a + b)(a + b)
= a² + ab + ab + b²
= a² + 2ab + b²
The fully expanded expression for the area of a square with sides of length a + b is a² + 2ab + b².
The area of a square is given by the formula: Area = side × side.
In this case, the side of the square is a + b.
Therefore, the expression for the area of the square is:
Area = (a + b) × (a + b).
To fully expand this expression using the distributive property, we'll apply the FOIL method (First, Outer, Inner, Last):
Area = a(a + b) + b(a + b)
= a² + ab + ab + b²
= a² + 2ab + b².
So, the fully expanded expression for the area of a square with sides of length a + b is a² + 2ab + b².

The dilated cone's with surface area of 2,250π in^2 has a volume of about 12500π in³
What is dilation?
Dilation is the increase or decrease in the size of a figure.
The cone has surface area 360π in² and volume 800π in^3. the cone is dilated, and the surface area of the dilated cone is 2,250π in^2.
Hence:
Scale factor² = dilated cone area / cone surface area
scale factor² = 2250π / 360π
Scale factor = 2.5
Volume of dilated cone = 2.5³ × 800π = 12500π in³

a formula for 6 gallons of light green paint uses 3/8 gallon of white paint. Liam has 9/16 gallon does Liam have enough white paint to make 8 gallons of light green paint?
Given:
6 gallons of light green paint uses [tex]\dfrac{3}{8}[/tex] gallon of white paint.
Liam has [tex]\dfrac{9}{16}[/tex] gallon of white paint.
To find:
Whether Liam have enough white paint to make 8 gallons of light green paint.
Solution:
Here, 6 gallons of light green uses [tex]\dfrac{3}{8}[/tex] gallon of white paint.
So, the white paint for 1 gallon of light green [tex]=\dfrac{\dfrac{3}{8}}{6}[/tex]
[tex]=dfrac{3}{8\times 6}[/tex]
[tex]=\dfrac{3}{48}[/tex]
[tex]=\dfrac{1}{16}[/tex]
It means, 1 gallons of light green uses [tex]\dfrac{1}{16}[/tex] gallon of white paint.
White paint for 8 gallon of light green [tex]=8\times \dfrac{1}{16}[/tex]
[tex]=\dfrac{8}{16}[/tex]
She has [tex]\dfrac{9}{16}[/tex] gallon of white paint, which is greater than [tex]=\dfrac{8}{16}[/tex] gallons.
Therefore, Liam have enough white paint to make 8 gallons of light green paint.
If Liam has 9/16 gallon, he has enough white paint to make 8 gallons of light green paint
Given that 6 gallons of light green paint use 3/8 gallon of white paint, this can be expressed as:
3/8 gallons of white paint = 6 gallons of light green
We are to determine if 9/16 gallons will be enough to make 8 gallons of light green paint. This can be expressed as
9/16 gallons of white paint = x
Divide both expressions
3/8 * 16/9 = 6/x
2/3 = 6/x
Cross multiply
2x = 3 * 6
2x = 18
x = 18/2
x = 9
This shows that if Liam has 9/16 gallon, he has enough white paint to make 8 gallons of light green paint

You plant a tomato plant in your garden. It starts at 8 inches tall. After 1 week, it grows to 11 inches tall. After two weeks, it is now 14 inches tall. After 3 weeks, the plant is 17 inches tall. Write a linear equation that represents this model. How tall is the tomato plant after 56 weeks?
Answer:
The tomato plant is 176 inch tall after 56 weeks.
Step-by-step explanation:
x ⇒ weeks and y ⇒ inch.
Week 0 the tomato plant starts at 8 inch tall, week 1 it grows to 11 inch tall, week 2 it grows to 14 inch tall, week 3 it grows to 17 inch tall, week 56 is ? inch tall. So, every week (x) the tomato plant grows 3 inch (y).
y = 3x + 8
y = (3 × 56) + 8
y = 168 + 8
y = 176 inch
[tex]h(n) = 8 + 3n[/tex]
Using the function, after 56 weeks, the height of the plant is of 176 feet.The linear model for the height after n weeks has the following format:
[tex]h(n) = h(0) + an[/tex]
In which:
h(0) is the initial height. a is the rate of change.Starts at 8 inches tall, thus h(0) = 8. Each week the height increases 3 inches, thus, a = 3, and the model is:
[tex]h(n) = 8 + 3n[/tex]
After 56 weeks, the height is of h(56), thus:
[tex]h(56) = 8 + 3(56) = 176[/tex]
176 inches tall after 56 weeks.
