Answer:

C) ∠LMO = 50°

Step-by-step explanation:

When you add the degrees of all the angles in a triangle, you get 180, so...

180 = 60 + 70 + x

180 - 60 - 70 = x

x = 50

3.) Write the equation of a quadratic function that is shifted down 4 and horizontally compressed by 1/5
sashaice [31]

Answer:

5x^2 - 4

Step-by-step explanation:

For shifted down a function you have to follow the next structured:

f(x) - c

In our case is:

x^2 - 4

Now for compressed or shrink a graph you have to multiply by a factor in the input something like this:

f(cx)

In our case is:

5x^2

Maybe you can think, why 5 and not \frac{1}{5} instead?. Well, when you multiply by \frac{1}{5} this dilate or stretch the graft because the output of each value is smaller, example:

f(x) = x^2\\g(x) = \frac{1}{5} x^2

Then evaluate for a number, for example 5:

f(5) = 25\\g(5) = 5

the output of g(x) is 5 steps a far from the answer of f(x) this in a graph is illustrate as a stretching.

So the opposite happen when you multiply by a integer number, the graph is compressed because the output take the "faster steps".

So combine the two transformation and get 5x^2 - 4

A tablespoon is equivalent to about 4 teaspoons. A recipe calls for 2/3 cup of sugar for every 1/2 teaspoon vanilla. What is the
nika2105 [10]

Answer:

I understand the exercise is about unit rates, but why go out of the way to state false information? A tablespoon is exactly 3 teaspoons!

Anyway,

(1/2 tsp)/(2/3 cup) * (1tbsp)/(4tsp) = 1/2 * 3/2 * 1/4 = 3/16 tbsp/cup

Step-by-step explanation:

Ok

Help me please, its mathwatch
mars1129 [50]

Answer:

<h2>60 cm^2</h2>

Solution,

Let ,

a = 13

b = 13

c= 10

then,

s = a + b + c /2

= 13 + 13 + 10 / 2

= 36/2

= 18

Now,

Area of triangle:

\sqrt{s(s - a)(s - b)(s - c)}

\sqrt{18(18 - 13)(18 - 13)(18 - 10)}

\sqrt{18 \times 5 \times 5 \times 8}

\sqrt{3600}

60 \:  {cm}^{2}

Hope this helps ....

Good luck on your assignment...
