Answer:

B is the answer

Step-by-step explanation:

Since there is already a 90 degree angle in the right triangle, the other two angles must add up to 90.

$3x + 6 + 2x - 1 = 90$

$5x + 5 = 90$

$5x = 85$

$x = 17$

Plug 17 into both to find the smaller angle

$3(17) + 6 = 57$

$2(17) - 1 = 33$

$33 < 57$

So 33 is the answer or B

Calculate the area of a circle with a dime tier of 16cm pi=3

Mashcka [7]

The area of every circle is (pi) (radius²) .

Radius = 1/2 of the diameter, so the area of your circle is

(pi) x (8 cm)² = 201 cm² . (rounded)

(pi) is not 3 . There's nothing wrong with approximating (pi),
but 3 is more than 4.5% wrong, and that's too much. There's
no reason why 3.14 should be too hard to handle.

Multiply the polynomials (x+4)(x^2-5x+3)

tatiyna

(4x2 – 4x – 7)(x + 3)
 = (4x2 – 4x – 7)(x) + (4x2 – 4x – 7)(3)
 = 4x2(x) – 4x(x) – 7(x) + 4x2(3) – 4x(3) – 7(3)
 = 4x3 – 4x2 – 7x + 12x2 – 12x – 21
 = 4x3 – 4x2 + 12x2 – 7x – 12x – 21
 = 4x3 + 8x2 – 19x – 21

What are transformation possible to change f(x) to g(x) on graph linear equation

Korolek [52]

Answer:

<h2>Vertical stretch or compression and vertical shift.</h2>

Step-by-step explanation:

When we talk about the transformation of functions, we can mention stretching, rotating, dilating, shifting. However, when we want to transform linear functions, there are only two transformations that are worthy in that case, those are vertical stretch or compression and vertical shift.

Now, you may ask, why only vertical transformation? the reason behind that is because horizontal transformation would give the exact same result because it's only a straight line which we are transforming.

Another common question would be, why only two transformations? it's because with these two you can get all the results because it's a straight line.
