Answer:
(-6, 1)
Step-by-step explanation:
If f(1) = 8 and f(n) = -4f(n-1) + 5 then find the value of f(3).
Answer:
f(3) = 113
Step-by-step explanation:
Using the recursive rule and f(1) = 8 , then
f(2) = - 4f(1) + 5 = - 4(8) + 5 = - 32 + 5 = - 27
f(3) = - 4f(2) + 5 = - 4(- 27) + 5 = 108 + 5 = 113
Help me, please! I need help with this.
Answer:
x = 9
Step-by-step explanation:
Because the angles are vertical angles their measures are congruent so make them equal to each other:
3x -8 = 2x +1 subtract 2x from both sides
-2x -2x
x -8 = 1 add 8 to both sides
+8 +8
x = 9

Answer:
a) 5²/4². b) 4.2²/2.8²
This is your answer ☺️☺️
a. [tex]\frac{5}{4}[/tex]
b. [tex]\frac{3}{2}[/tex] or [tex]1\frac{1}{2}[/tex]
Steps:For a.)Apply radical rule: [tex]\sqrt[n]{\frac{a}{b} } =\frac{\sqrt[n]{a}}{\sqrt[n]{b} }[/tex], assuming [tex]a\geq 0,b\geq 0[/tex]= [tex]\frac{\sqrt{25} }{\sqrt{16} }[/tex][tex]\sqrt{16}=4[/tex]
[tex]\frac{\sqrt{25} }{4}[/tex]
[tex]\sqrt{25} =5[/tex]
[tex]=\frac{5}{4}[/tex]
For b.)[tex]\frac{\sqrt{18} }{\sqrt{8} }[/tex]Apply radical rule: [tex]\frac{\sqrt{a} }{\sqrt{b} } =\sqrt{\frac{a}{b} }[/tex]Which means[tex]\frac{\sqrt{18} }{\sqrt{8} }=\sqrt{\frac{18}{8} }[/tex][tex]=\sqrt{\frac{18}{8} }[/tex]
2. Cancel [tex]\frac{18}{8}[/tex]: [tex]\frac{9}{4}[/tex]
= [tex]\sqrt{\frac{9}{4} }[/tex]
Now apply the radical rule: [tex]\sqrt[n]{\frac{a}{b} } =\frac{\sqrt[n]{a} }{\sqrt[n]{b} }[/tex] assuming [tex]a\geq 0,b\geq 0[/tex]
= [tex]\frac{\sqrt{9} }{\sqrt{4} }[/tex][tex]\sqrt{4}=2[/tex]
[tex]=\frac{\sqrt{9} }{2}[/tex]
[tex]\sqrt{9}=3[/tex]
The final answer for b.) should be [tex]\frac{3}{2}[/tex]

ANSWER THIS NOW please. An amusement park constructed a new ride called the "Haunted Hotel." There are x2 –
3 floors in this hotel. Each floor is 2x2 + 5 feet high. Which expression shows the total
height of this hotel?
Answer:
2x⁴ - x² - 15
Step-by-step explanation:
(X² - 3)(2x² + 5)
[x²(2x² + 5)] - [3(2x² + 5)]
= 2x⁴ - x² - 15

If Matt earns eight dollars per hour and h is the number of hours Matt works, which expression represents how much money Matt earns?
Answer:
8(h)=x
Step-by-step explanation:
Matt earns 8 dollars for every hour he works. So you multiply the total numbers worked (h) by 8. That will give you the amount of money he's made(x) so the equation would be 8(h)=x

An angle measures 27.2° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation:
Supplementary angles have a sum of 180 degrees.
a+a-27.2=180
2a-27.2=180
2a=207.2
a=103.6, and since b=a-27.2
b=76.4
So one angle is 103.6 degrees and the other is 76.4 degrees.
Convert the quadratic equation y=−4(x−3)(2x+4) from factored form to standard form.

The length of a rectangle is (3x - 1) and its width is ( 2x + 5). What is the area of the rectangle?
Answer:
3x^2 + 13x - 5
Step-by-step explanation:
To find the area, you multiply the length by width. So its is (3x - 1) * (2x + 5)
Then distribute. (3x * 2x) + (3x *5) + (-1 *2x) + (-1 * 5)
So 3x^2 + 15x -2x -5
Final Answer: 3x^2 + 13x - 5
