Which transformation would result in the perimeter of a triangle being different from the perimeter of its image?

1 answer:

8 0

Could be:
a similarity (would keep only the measurement ratios)
an affine transformation (preserves only parallelism)
<span>a projective transformation (preserve collinearity only)
</span>and some others

What is the equation, in slope-intercept form, of the line that passes through the points (−24, 5) and (16, −20)?

ser-zykov [4K]

Answer:

C (Y = -5/8x - 10)

Step-by-step explanation:

first find the slope (y₂ - y₁) ÷ (x₂ - x₁)

(5 - (-20)) ÷ (-24 - 16)

-5/8 = slope (m)

now that we know the slope is -5/8 we can rule out A and B

now to find the y intercept just substitute a point in for x and y

5 = (-5/8)(-24) + b

multiply

5 = 15 + b

subtract 15 from both sides tp isolate b

-10 = b

If 2x – 1 is a factor of 16x4<br> 24x3 + 2x + f, find f.

Nastasia [14]

Answer:

f = -5

Step-by-step explanation:

If 2x – 1 is a factor of 16x4 + 24x3 + 2x + f, find f.

If 2x - 1 = 16x⁴ + 24x³ + 2x + f, find f.

2x - 1 = 0

2x = 1

x = 1/2

Hence

f(1/2) = 16(1/2)⁴ + 24(1/2)³ + 2(1/2) + f

= 16(1/16) + 24(1/8) + 1 + f

= 1 + 3 + 1 + f

= 5+ f

f = -5

Which expression can be used to determine the average rate of change in f(x) over the interval mc001-1.jpg

Mrac [35]

The average rate of change of a function f(x) over an interval (a, b) is given by
$\frac{f(b)-f(a)}{b-a}$

Therefore, given a function, f(x), over an interval (2, 9), the average rate of change of the function can be found using the expression
$\frac{f(9)-f(2)}{9-2}$
