he difference between the expressions (2x² + 6x – 11) and (5x² – x + 5) will be –3x² + 7x – 18. Then the correct option is D.
<h3>What is subtraction?</h3>
It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.
The expressions are given below.
(2x² + 6x – 11) and (5x² – x + 5)
Then the difference between the expressions (2x² + 6x – 11) and (5x² – x + 5) will be
⇒ (2x² + 6x – 11) - (5x² – x + 5)
⇒2x² + 6x – 11 – 5x² + x – 5
⇒ –3x² + 7x – 18
Then the correct option is D.
The complete expression is given below.
(2x² + 6x – 11) and (5x² – x + 5)

The formula for surface area of a sphere is A=4*PI*r^2
Using that formula and the known surface are we can find the radius. We can then use that to find the volume.
500 = 4*PI*r^2
Divide both sides by 4:
500/4 = PI *r^2
125 = PI *r^2
Divide both sides by PI
125/PI = r^2
39.79 = r^2
r = SQRT(39.79)
r = 6.3 cm
Now we can find volume using V=4/3*PI*r^3
V = 4/3 *PI *6.3^3
V= 1051.3
The answer is C
Answer:
I'm not sure if this is right but y=x
Step-by-step explanation:
Answer:
D. y[9]=15.5410
Step-by-step explanation:
Let's find the answer by using the following observation:
Notice that the y-value differences between consecutives obstacles are:
(y-value from obstacule 2) - (y-value from obstacule 1)= 7.975 - 7.25 = 0.725
which is equal to:
(y-value from obstacule 1) / 10 = 7.25 / 10 = 0.725
So, an equation can be written as follows:
y[i+1]=y[i]+y[i]/10 let's find the other values:
y[2]=7.25+(7.25/10)= 7.975
y[3]=7.975+(7.975/10)= 8.7725
y[4]=8.7725+(8.7725/10)= 9.64975
Notice that we obtained the same y-values using the formula as the ones reported. So using the same formulas we can calculate:
y[9]=15.5410
In conclusion, the general equation is y[i+1]=y[i]+y[i]/10 with a starting point (1, 7.25) and y[9]=15.5410. So the answer is D.
