Step-by-step explanation:
<u>Y2 - Y1</u>
X2 - X1
<u>3 - 1</u>
2 - 1
= 2
y - Y1 = m (x - X1)
y - 1 = 2(x - 1) --- IN POINT SLOPE FORM
y - 1 = 2x - 2
+ 1 + 1
y = 2x - 1 --- IN SLOPE INTERCEPT FORM
QUESTION 12:
Slope intercept form -
- y = mx + b
- m represents the slope
- b represents the y - intercept AKA the starting point
- When the slope is negative, you go down
- When the slope is positive, you go up
ABOUT PROBLEM:
- Since the slope is negative, you go down 4, right 3, but start from the 2 then start doing the slope
- You have to put 2 on the y - line because it's the y - intercept AKA starting point
y = -4/3x + 2
Answer:
a) 301.6 cm³
b) 188.5 cm²
Step-by-step explanation:
The volume and lateral surface area of the cone can be found using the given dimensions with the given formulas. All that is needed is to substitute the appropriate values and do the arithmetic.
__
<h3>a) volume</h3>
The volume is given by the formula ...
V = 1/3πr²h
The dimensions are given on the diagram: r = 6 cm, h = 8 cm. Using these values in the formula, we find the volume to be ...
V = 1/3π(6 cm)²(8 cm) = 96π cm³ ≈ 301.6 cm³
The volume of the cone is about 301.6 cm³.
__
<h3>b) area</h3>
The lateral area of the cone is given by the formula ...
A = πrl
The dimensions are given on the diagram: r = 6 cm, l = 10 cm (the slant height). Using these values in the formula, we find the area to be ...
A = π(6 cm)(10 cm) = 60π cm² ≈ 188.5 cm²
The area of the curved surface is about 188.5 cm².
It’s a binomial cause there’s two terms
<u>ANSWER:
</u>
The total cost of the skate board is $74.61.
<u>SOLUTION:
</u>
Given, Luis wants to buy a skateboard that usually sells for $79.99. all merchandise is discounted by 12%. luis has to pay a state sales tax of 6.75%.
We need to find what is the total cost of the skateboard.
Final cost is nothing but original amount subtracted by discount and added with tax.
final cost = original cost – discount + sales tax
Original cost = $79.99
Discount = 12% of original cost

discount is $9.6 approximately
Sales tax = 6% of cost after discounting

Sales tax is $4.22 approximately
Now, final cost = 79.99 – 9.6 + 4.22
= 84.21 - 9.6
= 74.61
Hence, the total cost of the skate board is $74.61
