How can you determine congurence and similarity

Mathematics
1 answer:
leonid [27]3 years ago

Here you go :) AA (Angle-Angle) If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

A company sells widgets. The amount of profit y made by the company is related to the selling price of each widgets x by the giv
SCORPION-xisa [38]

Answer:

The maximum amount of profit is 32

Step-by-step explanation:

Given

y=-x^2+64x-292

Required

Determine the maximum profit

This is calculated by calculating the maximum of the function.

A quadratic function is of the form

y = ax^2 + bx + c

and its maximum is:

Max = \frac{-b}{2a}

So: y=-x^2+64x-292

We have that

a = -1

b = 64

c = -292

Max = \frac{-b}{2a}

Max = \frac{-64}{2 * -1}

Max = \frac{-64}{-2}

Max = 32

<em>Hence, the maximum amount of profit is 32</em>

PLS HELP ILL GIVE BRAINLIEST<br> What are the coordinates of the center of the ellipse?
yulyashka [42]

Answer:

Step-by-step explanation:

Standard equation of an ellipse,

\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1

(h, k) is the center of the ellipse

Value of a = Distance of the center from the vertex

b = Distance of the center from the covertex

From the picture attached,

a = Distance of the center (h, k) from the vertex (2, -2) = 3 units

b = Distance of the center (h, k) from the co-vertex (-1, 0) = 1 unit

Center of the ellipse (h, k) = (-1, -2)

One car model costs $12,000 and costs an average of $0.10 per mile to maintain. Another car model costs $14,000 and costs $0.08
BlackZzzverrR [31]
Answer:
See a solution process below:
Explanation:
Let's call the number of miles driven we are looking for
m
.
The the total cost of ownership for the first car model is:
12000
+
0.1
m
The the total cost of ownership for the second car model is:
14000
+
0.08
m
We can equate these two expressions and solve for
m
to find after how many miles the total cost of ownership is the same:
12000
+
0.1
m
=
14000
+
0.08
m
Next, we can subtract
12000
and
0.08
m
from each side of the equation to isolate the
m
term while keeping the equation balanced:
−
12000
+
12000
+
0.1
m
−
0.08
m
=
−
12000
+
14000
+
0.08
m
−
0.08
m
0
+
(
0.1
−
0.08
)
m
=
2000
+
0
0.02
m
=
2000
Now, we can divide each side of the equation by
0.02
to solve for
m
while keeping the equation balanced:
0.02
m
0.02
=
2000
0.02
0.02
m
0.02
=
100000
After 100,000 miles the total cost of ownership of the two cars would be the same.

Which ordered pair is a solution to the equation y = -6x?
navik [9.2K]

Answer:

(-10; 60)

Step-by-step explanation:

y = -6x

(12; -2)

-2 = -6 · 12

-2 = -72 - no

(3; -9)

-9 = -6 · 3

-9 = -18 - no

(-10; 60)

60 = -6 · (-10)

60 = 60 -  yes

(18; -3)

-3 = -6 · 18

-3 = -78 - no
