Answer:
a = 1/8
b = 8
Step-by-step explanation:
a (1/2) ^3 = (1/2) *(1/2) * (1/2) = 1/8
b( 1/2 ) ^ -3 The negative exponent means 1 / (1/2)^3 = 1/ (1/8) = 8
Solving right triangles
Answer:
i can see the actual question, what is it?
In right triangles one of the angles will always be 90 degrees.
So if you had a right triangle with one right angle, a number, and a number, they always have to add up to 90 degrees as well, because a triangle is always 180 degrees
so
side a = 90side b = xside c = yx + y = 90x + y + 90 = 180Guys I need your help , what is - 16t2 + 64+ + 3?

A rectangle is 20 cm long and 8 cm wide find the perimeter
(1 Point)
56 cm
28 cm
110 cm
52 cm
12% of 4 meters ( in cm)
Answer:
48 cm
Step-by-step explanation:
percent x meters x centimeters in meters
.12 x 4 x 100
Answer:
48 cm
Step-by-step explanation:
12/100 * 4 = 48 meters
1 meter = 100 cm
0.48 m = x Cross Multiply
1*x = 0.48 * 100
x = 48 cm

What is the solution to the system of equation?
Answer:
x = 0
y = 3
Step-by-step explanation:
-x - 2y = - 6
0 - 2(3) = -6
6 = 6
-3x + 2y = 6
-3(0) + 2(3) = 6
0 + 6 = 6

which of the following are equivalent to the expression below? sqrt -16
A. 4i
B. -4
C. -4i
D. 4
Answer:
A and C
Step-by-step explanation:
Using the fact that [tex]\sqrt{-1}[/tex] = i , then
[tex]\sqrt{-16}[/tex]
= [tex]\sqrt{16(-1)}[/tex]
= [tex]\sqrt{16}[/tex] × [tex]\sqrt{-1}[/tex]
= ± 4 × i
= 4i → A
= - 4i → C

Answer:
A. x = 3, y = -3
B. a = -2, b = 5
C. try your best ill see u later
Step-by-step explanation:
Okay I'mma state some stuff first 3^a + 3^b = 3^(a+b)
and 3^a/3^b = 3^(a-b)
So first equation 3^3*3^-3=3^0
So second equation 3^3/3^-2 = 3^5
So third equation I dont really know the rule but I'mm just plug in a random number for g, like 2, then solve the thing like a normal equation.
So 3^-3 x f^-3 = 12^2 = 144, f^-3 = 144/(3^-3 or 1/27) = 144 x 27 = 3888
so f^-3 = 3888, f = well its an imaginary number according to calculator so u try your best on the last one
Which of
below equations has a graph that passes
through the points (2, 3) and (0,-1) ?
Answer:
D
Step-by-step explanation:
Point slope formula y-y1=m(x-x1)
slope formula y1-y2/x1-x2
Points provided (2, 3) and (0,-1)
Let's find the slope. To find slope we need to plug in our numbers in the slope formula (y1-y2/x1-x2)
3-(-1)/2-0
4/2
=2
so slope (m) is 2
Now let's plug this in our point-slope formula (y-y1=m(x-x1)) with one pair of points (2,3)
y-3=2(x-2)
so, therefore, our answer is D!

Step-by-step explanation:
Step 1: Define
Identify
[tex]\displaystyle f(x) = \left \{ {{\sqrt{x + 1}, \ x < 3} \atop {5 - x, \ x \geq 3}} \right.[/tex]
Step 2: Find Right Limit
Substitute in variables [Right-Side Limit]: [tex]\displaystyle \lim_{x \to 3^+} 5 - x[/tex]Evaluate limit [Limit Rule - Variable Direct Substitution]: [tex]\displaystyle \lim_{x \to 3^+} 5 - x = 5 - 3[/tex]Subtract: [tex]\displaystyle \lim_{x \to 3^+} 5 - x = 2[/tex]∴ the right-side limit equals 2.
Step 3: Find Left Limit
Substitute in variables [Left-Side Limit]: [tex]\displaystyle \lim_{x \to 3^-} \sqrt{x + 1}[/tex]Evaluate limit [Limit Rule - Variable Direct Substitution]: [tex]\displaystyle \lim_{x \to 3^-} \sqrt{x + 1} = \sqrt{3 + 1}[/tex][√Radical] Add: [tex]\displaystyle \lim_{x \to 3^-} \sqrt{x + 1} = \sqrt{4}[/tex][√Radical] Evaluate: [tex]\displaystyle \lim_{x \to 3^-} \sqrt{x + 1} = 2[/tex]∴ the left-side limit equals 2.
Step 4: Find Limit
The right and left-side limits are equal.
∴ [tex]\displaystyle \lim_{x \to 3} f(x) = 2[/tex]

Monique borrows $5000 for 3 years at 8% per annum simple interest.
How much interest is she charged?
What total amount must she repay?
Answer:
1200 dollars for interest, she must pay 6200
Step-by-step explanation:
8 percent of 5000 is 400 times 3 (years) is 1200
Answers:
a) $1200 in interest is charged.b) $6200 must be paid back in total.=============================================
Work Shown:
a)
i = P*r*t
i = 5000*0.08*3
i = 1200 is charged in simple interest
---------------------------
b)
She must pay back the amount borrowed ($5000) which is the principal as well as the interest calculated in part a) earlier.
The total amount she must pay back is 5000+1200 = 6200 dollars

Write an inequality that represents this situation and indicate what the solution to the inequality will look like.
Answer:
x ≤ $12 a day
Step-by-step explanation:
5000-1400=3600
3600/300=12

Review this code snippet: var time = 15; var greeting; if ( time < 12 ) { greeting = “good morning”; } else if ( time < 18 ) { greeting = “good afternoon”; } else { greeting = “good evening”; } console.log(greeting); What is the message that gets printed to the console?
Explanation:
We're given that time = 15
From this, we see that time < 12 evaluates to false, because 15 is not smaller than 12. Put another way, 15 < 12 is false.
But time < 18 is true since 15 < 18 is true. So we execute the second block of code and have the greeting variable be set to the string "good afternoon". This is what's displayed to the console without any quotes of course.
Layla and Bobby are making potholders with their grandmother. They have a total of 1.5 yards of fabric they can use, and it takes one-eighth of a yard to make each potholder. What is the maximum number of potholders they can make?

which number is represented by the number line
Answer: B
Step-by-step explanation: The number line has tally marks up to 3, so 3 has to be divided by something, meaning A and C do not work. There are 9 total tally marks circled, so the equation equals 9, leaving B as the only possible answer. Also, there are three tally marks per whole number, so each tally is 1/3, which is equal to 2/6, further proving it is B.
At the dress shop, Sherry is building buttons into packages. She has reached the 867 th button and is packing the 34 th package when she is asked to take her lunch break . She needs to note the number of buttons that are in the package so when she returned she will continue she will continue . How many buttons does package 34 contain? dont send in file explain plz
Answer:
9 buttons in package 34
Step-by-step explanation:
There are 26 buttons in each box.
26 * 33 = 858 for the first 33 full boxes
867 - 858 = 9 buttons in the 34th box
B = buttons per box
33*B<867 --> B < 26.27
34*B>867 --> B > 25.5
So 25.5 < B < 26.27, therefore B = 26 buttons per box
