The answer is D
Explanation:5x^5-44x^3-9x=0
X(5x^2+1)(x-3)(x+3)=0
X(x+3)(x-3)=0
X=0,x=-3,x=3
All are congruent. Congruent means identical in size or shape. the different markings on the two shapes show that they are congruent. I can’t fully see number 10 so I can’t say it that one is or not
Answer:
Line equation is y=-x+11
The product of the slope and the y-intercept is -11
Step-by-step explanation:
Use the slope formula to find the slope of the equation.
yvalue2 minus yvalue1 /xvalue 2 minus xvalue1
-1-3/12-8=-1
The slope is -1.
Now, use the slope-intercept formula to find the y-intercept
y-3=-1(x-8)
y-3=-x+8
y=11
The equation is y=-x+11
The product of the slope and the y-intercept is -1(11)=-11
Hope this helps.
The value of the quantity after 99 months is 5228.58.
Given that, an initial value = 5900, rate of decay = 0.85% and time period = 7 years.
<h3>What is the exponential decay?</h3>
The quantity decreases slowly after which the rate of change and the rate of growth decreases over a period of time rapidly. This decrease in growth is calculated by using the exponential decay formula.
The exponential decay formula formula is 
Here, the value 
= 5900×
= 5900×0.8862
= 5228.58
Therefore, the value of the quantity after 99 months is 5228.58.
