SAS similarity theorem: When two triangles have corresponding angles that are congruent and corresponding sides with identical ratios, the triangles are similar.
Two right angles are always congruent, but corresponding sides not always have identical ratios. For example, first right triangle has two legs of 3 and 4 lengths. Second triangle has two legs of 5 and 12 lengths. Then \frac{3}{5}  \neq  \frac{4}{12}. That is the mistake.

<span>Daniel has not satisfied all the conditions of the theorem. The corresponding sides of each of the right triangles must also be in proportion for the triangles to be similar.</span>

Consider the inverse function. Which conclusions can be drawn about f(x) = x2 + 2? Select three options. f(x) has a limited rang
PolarNik [594]

Answer:

f(x) has a limited range

f(x) has a maximum at the point (0, 2)

f(x) has a y-intercept at the point (0, 2).

Step-by-step explanation:

Given the function;

f(x) = x^2+2

The domain is the value of the input variables for which the function will exist. According to the expression given, the function exists on all real values of x. The same goes with range which deals with the output values. It also exists on all real values from 2 and above.

Hence f(x) have a limited range (since values less than 2 are not included compare to domain that exists on all real values) and does not have a restricted domain.

For the x intercept, x intercept occur at y = 0

substitute y = 0 into the function and get y

if y = f(x)

y = x^2+2

0 = x^2 + 2

x^2 = -2

x = 2i

Hence  f(x) does not have an x-intercept of (2, 0)

For the y intercept, y intercept occur at x = 0

substitute x = 0 into the function and get y

if y = f(x)

y = x^2+2

y = 0^2 + 2

y = 2

Hence  f(x) has a y-intercept at point (0, 2)

f(x) is at maximum if d(fx))/dx = 0

d(fx))/dx  = 2x

since  d(fx))/dx  = 0

0 = 2x

x = 0

substitute x = 0 into the function

f(x) = x^2 + 2

y = 0^2+2

y = 2

Hence f(x) has a maximum at the point (0, 2)

Jeff sold the pumpkins he grew for $7 each at the farmers market. If Jeff sold 30 pumpkins how much money did he make. Write an
SVEN [57.7K]

Jeff made $210 by selling 30 pumpkins.

Step-by-step explanation:

Given,

Selling price of each Pumpkin = $7

Number of pumpkins sold by Jeff = 30

We will multiply number of pumpkins sold by selling price per pumpkin.

Amount made by Jeff = Price per pumpkin * Number of pumpkins

Amount made by Jeff = 7 * 30 = $210

Therefore;

Jeff made $210 by selling 30 pumpkins.

devin began running a month ago to get back in shape.the first day he ran .5 miles. each day after that he ran 10% more than the
SpyIntel [72]
The formula for the sum of the a finite geometric series is this:
Sn = a((1-r^n) / (1-r))

The given values are:
n = 30
a = 0.5 mi
r = 1.10 (10% more each day)

S30 = 0.5 ((1-1.10^30) / (1-1.10))
S30 = 82.25 mi

After 30 days, he will have traveled 82.25 miles.
