<u>x</u><u>=</u><u>3</u><u>0</u><u>°</u>
Answer:
Cos x°=adjacent/hypotenuse
Cos x°=45/52
x°=Cos-¹(45/52)
x°=30°
Written in standard form, y decreased by 25 = 10 is y - 25 = 10
Now let's solve:
y - 25 = 10
y = 10 + 25
y = 35
to check:
35 - 25 = 10
so, y equals 35
Answer:
Dvds cost 12 games cost 19.
Step-by-step explanation:
Put the amount of dvds and video games into an equation and assign variables.
3x+2y=74
5x+2y=98
You can solve multiple ways, although I'll do graphing for this equation.
After graphing, you get 2 lines that intersect. The point of intersection is 12,19 meaning that a dvd is 12 (x) and a video game is 19 (y)
Given that the triangle is an isosceles right angled triangle, then the value of x will obtain using the Pythagorean theorem, given by:
c^2=a^2+b^2
where
c is the hypotenuse, a and b are the legs
thus
x^2=12^2+12^2
x^2=144+144
x^2=288
hence
x=√288
x=√(2×144)
x=2√12
Answer:
The inverse of this function would be h(x) = x^5 + 4
Step-by-step explanation:
In order to find the inverse, start by switching the h(x) and the x values. Once you've done that, solve for the new h(x). That will be your inverse.
h(x) = ![\sqrt[5]{x - 4}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%20-%204%7D)
x = ![\sqrt[5]{h(x) - 4}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bh%28x%29%20-%204%7D)
x^5 = h(x) - 4
x^5 + 4 = h(x)
