Answer:
f(-3)=-1
f(4)=7
f(-1)=-3
f(12) = -24
Step-by-step explanation:
Piecewise Functions
The piecewise functions define different pieces or subfunctions where the domain is divided into parts according to some conditions on the independent variable.
The pieces of the function are defined as shown below:
[tex]f(x)=\left\{\begin{matrix}-1 &x\le -2\\ 2x-1 &-2<x\le 4 \\ -3x+8 &x>4 \end{matrix}\right.[/tex]
Let's find the values of:
f(-3). Here the variable x is -3. We have to find the interval where x=-3 belongs. Since -3 ≤ -2:
f(-3)=-1
f(4). The variable x is 4 and it belongs to the second interval, thus
f(4)=2*4-1=7
f(4)=7
f(-1). x = -1. It belongs to the second interval, thus:
f(-1)=2*(-1)-1=-3
f(-1)=-3
f(12). x=12 belongs to the last interval since 12 > 4, thus:
f(12)= -3*12+8 = -36 + 8 = -24
f(12) = -24

Answer:
C. 11 3/4
Step-by-step explanation:
3 + 3 + 2 + 2 = 10
1/4 + 3/4 + 1/4 = 1 1/4
1/2 -> 2/4
2/4 + 1 1/4 = 1 3/4
10 + 1 3/4 = 11 3/4
Which expression is equivalent to 3^4 ⋅ 3−^9?
Answer:
3^-5 = 1/3^5
Step-by-step explanation:
3^4 ⋅ 3−^9
When multiplying exponents and the bases are the same, we can add the exponents
a^b * a^c = a^ ( b+c)
3^4 ⋅ 3−^9
3^( 4-9)
3^-5
We know that a^ -b = 1/a^b
3^-5 = 1/3^5
Answer:
3^4 times 3^9 = 3^4 times 1/3^9

Answer:
C. 24.27 cm
Step-by-step explanation:
sin 65° = opposite ÷ hypotenuse
sin 65° = 22/x
multiply both sides of the equation by x
(sin 65°)x = 22
divide both sides of the equation by sin 65°
x = 22 ÷ sin 65°
punch in 65 sin into your calculator
x = 22 ÷ 0.90631
x = 24.27 cm

Answer:
multiply both sides by 8

Complete question:
Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs \$3.25$3.25dollar sign, 3, point, 25. Then, he wants to buy as many pancakes as he can, but he wants his bill to be at most \$30$30dollar sign, 30 before tax. The restaurant only sells pancakes in stacks of 444 pancakes for \$5.50$5.50dollar sign, 5, point, 50. Let SSS represent the number of stacks of pancakes that Benjamin buys. 1) Which inequality describes this scenario?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Cost of chocolate milk = $3.25
Cost of pancakes = $5.50 (stack of 4)
Number of stacks of pancakes purchased = S
Maximum amount spent ≤ $30
Cost of chocolate + (Cost of pancake stack * number of stacks) ≤ $30
3.25 + 5.50S ≤ 30
5.50S ≤ 30 - 3.25
5.50S ≤ 26.75
S ≤ 26.75 / 5.50
S ≤ 4.86
Hence maximum number of pancake stacks he can purchase without exceeding budget = 4
Hence total number of pancakes = number of stacks * number in a stack
= 4 * 4
= 16
Answer:
Chose option have answer 3.25+5.50S [tex]\leq[/tex] 30
16 pancakes

3. Find the slope of the line through the given points.
a. (34, 15), (16, 30)
Answer:
Step-by-step explanation:
Distance
23.43074902772
Midpoint
(25,22.5)
Slope
−0.833333333333333
x intercept
52.00
y intercept
43.33
What’s the value of x
7x -1 + 9x + 5 = 180
16x = 180 - 5 + 1
16x = 176
x = 176/16
x = 11
Step-by-step explanation:
(7x-1)+(9x+5)=180 ( since its a straight line )
16x+4=180
x= 11

Find the distance between the following two points: *
(3,6) and (9,2)
Answer:
Step-by-step explanation:
(3 , 6 ) ;( 9 , 2)
Distance = [tex]\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
[tex]= \sqrt{(9-3)^{2}+(2-6)^{2}}\\\\=\sqrt{6^{2}+(-4)^{2}}\\\\=\sqrt{36+16}\\\\=\sqrt{52}\\\\=\sqrt{2*2*13}\\\\=2\sqrt{13}[/tex]
