What is the equation of the axis of symmetry for the parabola y= 1/4(x+2)^2-7

Mathematics

Nezavi [6.7K]3 years ago

Your answer is -2 as the axis of symmetry is at -b/2a. So if you were to expand the equation, you would get y= x^2/4 +x -6 where b is 1 and 2a is ½ . Therefore -1 / ½ gives you -2

He lifted 100 kilograms and 132.5 kilograms. What was the combined weight of his lifts in grams?
Olegator [25]
So add them together
100+132.5=232.5 kg

kilograms=1000 grams so
232.5kg=1000 times 232.5 grams

232500 grams

Solve for x. The triangles in each pair are similar. <br>​
KatRina [158]

Answer:

Step-by-step explanation:

You need to pay very close attention to the triangle similarity statement.  This says that triangle NML is similar to triangle NVU.  But if you look at the way that triangle NVU is oriented in its appearance, it's laying on its side.  We need to set it upright so that angle N is the vertex angle, angle V is the base angle on the left, and angle U is the base angle on the right.  When we do that we see that sides NV and NM are corresponding and exist in a ratio to one another; likewise with sides VU and ML.  Setting up the proportion:

\frac{NV}{NM}=\frac{VU}{ML}

Filling in:

\frac{12}{36} =\frac{9}{9x}

Cross multiply to get

324 = 108x

and x = 3
