Can someone help me find x
Viefleur [7K]

Answer:

Rounded to the nearest tenth: x=5.7 in

Rounded to the nearest hundredth: x=5.74 in

Step-by-step explanation:

We have a right triangle with a given angle of 35°. We also have the opposite side of that angle, x, and its hypotenuse 10 in. To find x, we are using the trig function that relates  the opposite side with the hypotenuse; in other words, the sine trig function.

sin\alpha =\frac{opposite}{hypotenuse}

sin(35)=\frac{x}{10}

x=10sin(35)

x=5.735764364

Rounded to the nearest tenth: x=5.7 in

Rounded to the nearest hundredth: x=5.74 in

Plz help me with this
Marrrta [24]

Answer:  c) 3

<u>Step-by-step explanation:</u>

Plug in y = -9 and the given x-value to see if it makes a true statement.

a) -4.5 falls in the piecewise function x < -3  --> y = -x

y = -x

-9 = -(-4.5)

-9 = 4.5    FALSE

b) -3 falls in the piecewise function -3 ≤ x ≤ -2  --> y = 2x

y = 2x

-9 = 2(-3)

-9 = -6    FALSE

c) 3 falls in the piecewise function x > -2 --> y = -x²

y = -x²

-9 = -(-3)²

-9 = -9   TRUE

d) 9 falls in the piecewise function x > -2 --> y = -x²

y = -x²

-9 = -(9)²

-9 = -81   FALSE

Express as a trinomial: (2x-3)(x 5)
Illusion [34]
I am assuming the expression is (2x-3)(x+5) or (2x-3)(x-5). I will teach you how to solve for both as I am not sure which one you are asking for. There are 4 steps to multiplying.

1) Multiply the x times the second x
2) Multiply x times the second number
3) Multiply the number by the second x
4) Multiply the number by the second number.

(2x*x)+(2x*5)+(-3*x)+(-3*5)=(2x^{2})+(10x)+(-3x)+(-15)=2x^{2}+7x-15

(2x*x)+(2x*-5)+(-3*x)+(-3*-5)=(2x^{2})+(-10x)+(-3x)+(15)=2x^{2}-13x+15

Your answer is 2x^{2}+7x-15 or 2x^{2}-13x+15. Does that answer your question?

If the domain (or pre-image) is (-4, -2), (5, 9), (-6, 2) and the range (or image) is
Neko [114]

Answer:  90 degrees clockwise

This is equivalent to 270 degrees counterclockwise

The rule for either rotation is (x,y) \to (y,-x)

The x and y coordinates swap places, and the new second coordinate flips from positive to negative (or vice versa).

The diagram below shows an example of this for the point (-4,-2) rotating to (-2, 4). The center of the rotation is the origin (0,0).
