A triangle has angles measuring 45°, 55°, and 80°. It is dilated by a scale factor of 2. What are the angle measures, in order f

lbvjy [14]

Answer:

45°,55° and 80°.

Step-by-step explanation:

Dilations preserve angle measures, regardless of the scale factor. Therefore, the angle measures of the image will be the same of that of the pre-image, so our answer is still 45 °, 55 °, and 80 °.

Find the sum of the first 12 terms of the geometric sequence - 2,6,-18,54,-162....

nekit [7.7K]

Answer:

Sure, the common difference is -3, but like you have to multiple it and stuff, so it goes like this: -2,6,-18,54,-162,486,-1458,4374,-13122,39366,-118,098,354294.

So then, add all of the 12 terms I stated, and that will equal to 265,720

Therefore, the sum of the first 12 terms of that geometric sequence is 265,720.

Compute the value of the discriminant and give the number of real solutions of the quadratic equation.

Sergio039 [100]

$-2x^2+6x-3=0 \\ \\
a=-2 \\ b=6 \\ c=-3 \\ \Delta=b^2-4ac=6^2-4 \times (-2) \times (-3)=36-24=12$

The value of the discriminant is 12.
Since the discriminant is greater than zero, the equation has two real solutions.

a rectangle has a length of 11 feet and the perimeter of 38 feet. what the width in feet of the rectangle

Sati [7]

If p= 38
You need four sides to equal that
11 is length so that means two sides are 11
11+11= 22
So that means you need two more equal numbers that will finish making up the 22
38-22= 16
But two sides make up 16
16 divides by 2 is 8
So THE WIDTH IS 8
