Terri needs $250 to buy Christmas gifts this year. She has $75 saved already and she is saving $45 each week. Find the slope for
Andrei [34K]
$250 = $75 + ?
45 × 3 = 135
135 + 75 = 210
210 + 45 = 255
? = 180
$75 + ( 45 × 4 ) = 255
so she could save up 4 weeks worth of money plus the other 75 with an extra $5 to spend or save for something

Tan(30°) = 17/x
x = 17/tan(30°) = 17√3

The hypotenuse of the smaller triangle is as you show, 34.

sin(45°) = 34/y
y = 34/sin(45°) = 34√2

x = 17√3
y = 34√2

25. Algebraically determine whether the function k(x) = x6 - x2 + 7 is odd, even, or neither. Explain your
alekssr [168]

Answer: The function is EVEN.

Step-by-step explanation:

For this exercise it is important to remember that:

1. A function f(x) is even if and only if:

f(-x) = f(x) for all "x"

2. A function f(x) is odd if and only if:

f(-x) = -f(x) for all "x"

So knowing that, and given the following function k(x):

k(x)=x^6 - x^2 + 7

You can plug -x in for "x", order to know if this is even. Then, you get:

k(-x)=(-x)^6 - (-x)^2 + 7\\\\k(-x)=x^6-x^2+7

Therefore, since:

f(-x) = f(x)

You can determine that that the given function k(x)=x^6 - x^2 + 7 is Even.
