Answers

Answer:

A. Y = 5x + 10

Step-by-step explanation:

The bear gains 5 pounds a month. The X represents the months in which five pounds gradually build. This is represented by 5x. We need to add the bears original 10 pounds so Y = 5x + 10.

The area of a triangle is 528cm2. The length of its base is 33cm. Calculate the perpendicular height of the triangle

Answers

A = bh/2
A = 33 x h / 2
528 = 33h / 2
33h = 1056
h = 32cm

The perpendicular height of the triangle is  32 cm.

A triangle is a figure that has three sides. The three sides are length, base and hypotenuse. The sum of angles in a triangle is 180 degrees.

The area of a triangle = [tex]\frac{1}{2}[/tex] x base x height

In order to determine the height of the triangle, this formula would be used:

height = (2 x area) / base

(528 x 2) / 33

= 1056 / 33

= 32 cm

What is the discontinuity of the function f(x)= x^2-4x-12/x+2. PLEASE ASAP WILL GIVE BRAINLIEST!

Answers

Hello!

[tex]\large\boxed{\text{Infinite discontinuity at x = 2}}[/tex]

[tex]f(x) = \frac{x^{2} - 4x - 12}{x - 2}[/tex]

Recall that in a rational function, the denominator contains the vertical asymptote (an infinite discontinuity).

If terms can be canceled from the denominator and the numerator, then the function contains a hole. We can check whether this function contains such by factoring:

[tex]f(x) = \frac{(x - 6)(x + 2)}{x - 2}[/tex]

There is no common factor, so the function only contains a discontinuity at its vertical asymptote.

Find the vertical asymptote by setting the denominator equal to 0:

x - 2 = 0

x = 2.

Halona walks 1.93 kilometers to a neighbor’s house in 23 minutes. Assuming she walks at a constant speed, write a proportion that represents how many kilometers,y, Halona can walk in x minutes. Then solve your proportion for y.

Answers

Answer:

proportion: 1.93/23 = y/x

solve for y: y = x(0.083913)

Step-by-step explanation:

The required relationship of the proportionality is y = 0.08 x.

Given that,
In 23 minutes, Halona travels 1.93 kilometers to a neighbor's home. assuming she moves at a steady pace.
How many kilometers, y, Halona can walk in x minutes, expressed as a proportion. After that, find y using your percentage.

What is proportionality?

The relationship between two or more sets of values—whether they are directly proportional or inversely proportional to one another—is referred to as proportionality.

Here,
according to the question,
y ∝ x
y = kx
Where k is the constant of the proportionality,
at x = 23, y = 1.93
1.93 = 23 k
k = 1.93/23
k = 0.08
Put k in the proportionality equation,
y = 0.08k

Thus, the required relationship of the proportionality is y = 0.08 x.
