Answer:
f(x)=x2,g(x)=f(3x)=(3x)2=9x2
Now to graph y=9x2. This is a parabola (U-shape), vertex at (0, 0), symmetric around y axis. When x=1/3 or -1/3, then y=1.
Hope this helps! :))
Answer:
11,700cm²
Step-by-step explanation:
Area of the triangle = 1/2*JK sin<I
Given
J = 800cm
K = 240cm
<I = 173 degrees
Substitute
Area of the triangle = 1/2 * 800 * 240 sin 173
Area of the triangle = 400 * 240sin 173
Area of the triangle = 400 * 29.25
Area of the triangle = 11,699.5
Area of the triangle to the nearest square centimeter is 11,700cm²
Fraction of tank drops in every 10 minutes = 1/3 inches.
We need to find the expected change in the tank's water level after 2.25 hours.
Let us convert 2.25 hours in minutes.
1 hours = 60 minutes.
2.25 hours = 2.25 × 60 = 135 minutes.
<em>We need to divide 135 by 10.</em>
We get 13.5.
Now, we need to <em>multiply 1/3 by 13.5</em>, we get.
13.5/3 = 4.5 inches.
<h3>So, tank would drop 4.5 inches after 2.25 hours.</h3>
Answer:
r^2 + 6rs - 4rd - 2d^2 + 3s^2
Step-by-step explanation:
3(r+s)^2 - 2(r+d)^2
PEMDAS
parenthesis, exponents, multiplication, division, addition, subtraction
in that order
3( r^2 + 2rs + s^2 ) - 2(r^2+ 2rd + d^2)
3r^2 + 6rs + 3s^2 - 2r^2 - 4rd - 2d^2
r^2 + 6rs - 4rd - 2d^2 + 3s^2
Answer:
I think the answer would be Y= -2X+5 .
Hope it helps u ^^♥️
