Answer:

B is correct

Step-by-step explanation:

The person is mentioned is Phil. His amount of money and number of miles are proportionally related (Clark's amount of money and number of miles are not proportionally related due to initial donation)

For Phil, y = ax is his model.

Look into the graph, we can see there is a point where y = 30 and x = 4.

Then rate = 30/4 = 7.5

Find an equation of a line that goes through the points (1,6) and (4, -2). Write your answer in the form y=mx + y.

zmey [24]

Answer:

The desired equation is y = (-8/3)x + 26/3.

Step-by-step explanation:

Moving from (1,6) to (4, -2) involves an increase of 3 in x and a decrease of 8 in y. Thus, the slope of the line thru these two points is m = rise / run = -8/3.

Using the slope-intercept form of the eq'n of a straight line and inserting the data given (slope = m = -8/3, x = 4, y = -2), we get:

y = mx + b => -2 = (-8/3)(4) + b, or -2 = -32/3 + b

Multiply all terms by 3 to clear out the fraction:

-6 = -32 + 3b.

Then 26 = 3b, and b = 26/3.

The desired equation is y = (-8/3)x + 26/3.

Blank numbers can be written as a product of blank factors.This is called the prime factorization of a number.

noname [10]

Yes, the blank numbers that can be written as a product of blank factors are called the prime factorization of a number. It can also be composite numbers where it can be written also as the product of prime factors.

Answer:

Step-by-step explanation:

1. a). Hypotenuse² = (Leg 1)² + (Leg 2)²

h² = 10² + 24²

h = √676

h = 26

(b). Hypotenuse² = (Leg 1)² + (Leg 2)²

(25)² = (15)² + (leg 2)²

Leg 2 = √(625 - 225)

= √400

= 20

(c). Hypotenuse² = (Leg 1)² + (Leg 2)²

h² = 4² + 6²

h = √(16 + 36)

h = √52

h = 2√13

(d). Hypotenuse² = (Leg 1)² + (Leg 2)²

(14)² = (Leg 1)² + 7²

Leg 1 = √(196 - 49)

= √147

= 7√3

2). Hypotenuse² = (Leg 1)² + (Leg 2)²

Leg 1 = leg 2 = 7 units [Since, triangle is an isosceles triangle]

h² = 7² + 7²

h = √98

h = 7√2

Option (1) is the correct option.

3). Hypotenuse² = (Leg 1)² + (Leg 2)²

(26)² = (Leg 1)² + (10)²

Leg 1 = √(676 - 100) = 24

Area of a right triangle = $\frac{1}{2}(\text{Leg 1})(\text{Leg 2})$

= $\frac{1}{2}(24)(10)$

= 120 square units

Option (3) is the correct option.
