Answer: 48 feet
Step-by-step explanation:
Answer:
B.) You don't really have to worry about finding the slope. You just have to look for the y intercept, which is (0, -2)
Hope this helps! :)
Answer:
D
Step-by-step explanation:
Since x is squared, that's a non-linear equation because it's the only answer that, when graphed, doesn't form a straight line
Answer:
Vertex form: f(x) = -10(x − 2)^2 + 3
Standard form: y = -10x^2 + 40x - 37
Step-by-step explanation:
h and k are the vertex coordinates
Substitute them in the vertex form equation:
f(x) = a(x − 2)^2 + 3
Calculate "a" by replacing "f(x)" with -7 and "x" with 1:
-7 = a(1 − 2)^2 + 3
Simplify:
-7 = a(1 − 2)^2 + 3
-7 = a(-1)^2 + 3
-7 = a + 3
-10 = a
Replace a to get the final vertex form equation:
f(x) = -10(x − 2)^2 + 3
Convert to standard form:
y = -10(x − 2)^2 + 3
Expand using binomial theorem:
y = -10(x^2 − 4x + 4) + 3
Simplify:
y = -10x^2 + 40x - 40 + 3
y = -10x^2 + 40x - 37
Answer & Step-by-step explanation:
This is a proportion. To solve it, we need to set up the equation.
<h2>___________________________________________________</h2><h3>Step 1: Set up the Proportion</h3>
The proportion here needs to be expressed as:
Since this ratio is 3/2, we can set up the proportion as follows:
<h2>___________________________________________________</h2><h3>Step 2: Use Cross-Multiplication</h3>
2a = 3 × 36
3a = 216
<h3>a = 72</h3><h2>___________________________________________________</h2><h3>Step 3: Repeat for the Other Values</h3>
3b = 2 × 72
3b = 144
<h3>b = 48</h3><h3>___________________________________________________</h3>
3c = 2 × 126
3c = 252
<h3>c = 84</h3><h3>___________________________________________________</h3><h3><em>I AM ALWAYS HAPPY TO HELP :)</em></h3>
