Answer: g(x)-f(x)=8x-16

Explanation:

f(x)=-3x+4 (I am assuming "-3+4" is a typo and it is "-3x+4")

g(x)=5x-12

g(x)-f(x)=(5x-12)-(-3x+4)=5x+3x-12-4=8x-16

I need to find angle M

nadezda [96]

Answer:

m<AIR = 90 deg

Step-by-step explanation:

I assume the problem contains an error, and that AR is a diameter, not AC.

Look at the diameter of the circle, AR. It passes through the center of the circle, C. You can think of the two radii of the circle, CR and CA, as sides of angle RCA. Since AR is a diameter, and AR is a segment which is part of line AR, rays CR and CA are sides of an angle that lie on a line. That makes the measure of angle RCA 180 deg. Angle RCA is a central angle of circle C since its vertex is the center of the circle.

Angle AIR is an inscribed angle in circle C since its vertex is on the circle itself. If an inscribed angle and a central angle intercept the circle at the same two points, then the measure of the inscribed angle is half the measure of the central angle.

m<AIR = (1/2)m<RCA = (1/2) * 180 = 90

m<AIR = 90 deg

Mafalda has a save percentage of 0.7380.7380, point, 738 so far this hockey season. Last season, her save percentage was 0.5850.

Snowcat [4.5K]

Answer:

0.153

Step-by-step explanation:

We have been given that Mafalda has a save percentage of 0.738 so far this hockey season. Last season, her save percentage was 0.585.

To find improvement in Mafalda's save percentage we will subtract last season's save percentage from this season's save percentage.

$0.738-0.585=0.153$

Therefore, Mafalda's save percentage improved by 0.153.

Please please help i beg ill give brainlist

Answer:

$a_{15}=-268,435,456$

Step-by-step explanation:

First, find what factor each term is multiplied by to get to the next. To do this, divide the second term by the first, the third term by the second, etc

$4\div-1=-4\\-16\div4=-4\\64\div-16=-4$

The common factor is 4. Using that, you can now write the equation for the geometric sequence in the form of:

$a_n=a_1x^{n-1}$

It looks scarier than it is. aₙ is the nth term in the sequence, x is the factor, and n is the index in the sequence, that's all it is.

Plug in the information we have to get the equation for this sequence:

$a_n=(-1)(-4)^{n-1}$

Then, you can solve for the 15th term:

$a_{15}=(-1)(-4)^{15-1}\\a_{15}=(-1)(-4)^{14}\\a_{15}=(-1)(268,435,456)\\a_{15}=-268,435,456$

Basically, just raise the scale factor to the power of the term you want minus 1, then multiply that by the first number.
