To get the radius we proceed as follows:
area=θ/360πr²
area=40 sq. units
θ=110°
thus the value of r will be:
40=110/360πr²
r²=40(110/360*π)
r²=41.66966
r=6.4552

What are the x-intercepts of this quadratic function? g(x) = -2(x − 4)(x + 1) A. (4,0) and (-1,0) B. (-4,0) and (-1,0) C. (4,0)
My name is Ann [436]

Answer:

Option A. (4,0) and (-1,0)

Step-by-step explanation:

we know that

The equation of a vertical parabola in factored form is equal to

f(x)=a(x-x_1)(x-x_2)

where

a is a coefficient

x_1 and x_2 are the zeros or x-intercepts of the function

In this problem we have

g(x)=-2(x-4)(x+1)

we have

a=-2

The leading coefficient is negative, that means the parabola open downward

The zeros of the function are

x_1=4\\x_2=-1

Remember that the x-intercepts are the values of x when the value of the function is equal to zero

therefore

The x-intercepts are (4,0) and (-1,0)

Plz help I’m down bad atm

Answer: Second option, 2^2x+6=2^6

Step-by-step explanation:

You can simplify 4^x+3 by making the 4 into 2^2. By doing this you also multiply the current powers of 4 by 2, giving you (x+3) • 2, furthermore, 2^2x+6.

64 is a power of 2, so just multiply 2 by itself until you get the number you’re looking for and count how many times you do it. Or just type each option, like 2^4, 2^6 into the calculator until you find it.
