Answer:
30.25 & 33.25
Step-by-step explanation:
x² + 11x + (5.5)² = 3+ (5.5)²
x² + 11x + 30.25 = 33.25
F=I(1+rt), F=final amount, I=initial amount, r=rate, t=time
Here I=$5000, r=(4/100)=0.04 so
F=$5000(1+0.04t) so after 5 years...
F=$5000(1+0.2)
F=$6000
Answer:
See attached picture.
Step-by-step explanation:
The solution set on a graph is the graph or drawing of the function. For this quadratic function, it is the U-shaped graph called a parabola. Graph the equation by finding the x-intercepts and vertex.
The function factors into (x+4)(x+5). So the x-intercepts are -4 and -5.
The vertex of the function is found using -b/2a. Here that is -9/2 = -4.5. This is the x value of the vertex. The y-value is found by substituting x = -4.5 into the function.
(-4.5)^2 + 9(-4.5) + 20
20.25 - 40.5 + 20
Graph three points at (-4,0), (-5,0) and (-4.5, -0.25).
See attached picture for the graph.
Answer:
(this might be wrong but if your desperate) 518
Step-by-step explanation:
1. 70+52=122
2. 640-122= 518
