Find the value of c so that (x+3) is a factor of the polynomial p(x). p(x)=x^3-4x^2+cx+33
Answer:
The value of c is -10.
Step-by-step explanation:
Since (x+3) is a factor of the polynomial p(x).
We have that:
x + 3 = 0 -> x = -3
So p(-3) = 0
Then
[tex]p(x) = x^3 - 4x^2 + cx + 33[/tex]
[tex](-3)^3 - 4(-3)^2 - 3c + 33 = 0[/tex]
[tex]-27 - 36 - 3c + 33 = 0[/tex]
[tex]3c = -30[/tex]
[tex]c = -\frac{30}{3}[/tex]
[tex]c = -10[/tex]
The value of c is -10.
When using substitution to solve this system of equations, what is the result of the first step?
Answer:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
Step-by-step explanation:
Hope this helps you
Answer:
Solve. Because now you have only one variable.

How much money needa to be deposited now into an account to obtain 9,000 in 7 years if the interest rate is 8% per year compounded continuously?
Answer:
P: the principal, the amount invested
A: the new balance
t: the time
r: the rate, (in decimal form)
Step-by-step explanation:
Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160

désolé mais je ne sais pas.
Step-by-step explanation:
Please help would really appreciate it!
Answer:
[tex] r = 6\sqrt{3} [/tex]
Step-by-step explanation:
Area of the shaded section = θ/360*πr²
Area = 15π m²
θ = 360° - 310° = 50°
r = ??
If in the values into the equation and solve for r
15π = 50/360 × π × r²
[tex] 15 \pi = \frac{5 * \pi * r^2}{36} [/tex]
Multiply both sides by 36
[tex] 15 \pi * 36 = \frac{5\pi * r^2}{36}*36 [/tex]
[tex] 540 \pi = 5\pi * r^2[/tex]
Divide both sides by 5π
[tex] \frac{540 \pi}{5\pi} = \frac{5\pi * r^2}{5\pi} [/tex]
[tex] 108 = r^2 [/tex]
[tex] r = \sqrt{108} [/tex]
[tex] r = \sqrt{36*3} [/tex]
[tex] r = 6\sqrt{3} [/tex]

Answer:
F for number 14
Step-by-step explanation:
Fill in the blanks below in order to justify whether or not the mapping
shown represents a function.
first bank says , the mapping diagram above { represents } or does { NOT represent } a function since ..
blank 2 says { for each number } or { there is one number }
blank 3 says { set a the output } or { set b the input } or { set a the input } , and { set b the output } !
1) it's a function 2) for each number 3) set a input and set b output
to be a function, no ordered pairs should have same first coordinate, hence this is a function
solve the inequality 4x-1>15 but the > has a line under it .
Answer:
x ≥ 4
Step-by-step explanation:
Given the inequality 4x-1≥15
Add 1 to both sides
4x-1+1≥15+1
4x≥16
Divide both sides by 4
4x/4 ≥ 16/4
x ≥ 4
Hence the solution is x ≥ 4
