Answer:
Step-by-step explanation:
In the set [-5, 3], only A fits in. B is pi, which has a value of 3.1415....which is outside of the interval since it's greater than 3. C. is -6 which is less than -5, so that's outside of the interval as well. D is the square root of 36 which is 6...outside of the interval again. A it is. A could be rewritten as
[tex]-\frac{1}{2^2} =-\frac{1}{4}[/tex]

4. If m3 = 54°, find the measure of each missing angle
Answers
Answer:Answer/Step-by-step explanation:
Given that m<3 = 54°
a. <1, <2, and <3 are angles on a straight line. They add up to 180°.
m<3 is given as 54°, m<2 = 90°, therefore,
m<1 = 180 - (54 + 90) = 180 - 144
m<1 = 36°
b. <2 is indicated as a right angle. Therefore, m<2 = 90°
c. <1 and <4 are vertical opposite angles. Vertical angles are congruent, since m<1 = 36°, therefore, m<4 = 36°
d. <5 and <2 are vertical opposite angles. m<2 = m<5, therefore, m<5 = 90°
e. <6 and <3 are vertical opposite angles. m<3 = m<6, therefore, m<6 = 54°
f. m<7 + m<6 = 180° (same side interior angles are supplementary)
m<7 = 180 - m<6
m<7 = 180 - 54
m<7 = 126°
g. m<7 + m<8 = 180° (linear pair)
126° + m<8 = 180
m<8 = 180 - 126
m<8 = 54°
h. m<9 = 180 - m<8 (linear pair)
m<9 = 180 - 54
m<9 = 126°
i. m<10 = m<8 (vertical angles)
m<10 = 54°
j. m<11 = m<4 (alternate interior angles are congruent)
m<11 = 36°
k. m<12 = 180 - m<11 (linear pair)
m<12 = 180 - 36
m<12 = 144°
l. m<13 = m<11 (vertical angles)
m<13 = 36°
m. m<14 = m<12 (vertical angles)
m<14 = 144°
Step-by-step explanation:
Answer:
A. M<1 = 36°
B. M<2= 90°
C. M<4= 36°
D. M<5= 54°
E. M<6= 54°
F. M<7= 126°
G. M<8= 54°
H. M<9= 126°
I. M<10 = 54°
J. M<11 = 36°
K. M<12 = 144°
L. M<13= 36°
M. M<14 = 144°

Convert the binary number 10000010 to decimal.
Answers
Answer:
130
Step-by-step explanation:
First you want to start in the one's place in 10000010, multiply the ones place with 2^0
then move to the left to the tens place with 2^1
hundreds place with 2^2 an so on
Decimal equivalent of "0" = 0 × 2^0 = 0
Decimal equivalent of "1" = 1 × 2^1 = 2
Decimal equivalent of "0" = 0 × 2^2 = 0
Decimal equivalent of "0" = 0 × 2^3 = 0
Decimal equivalent of "0" = 0 × 2^4 = 0
Decimal equivalent of "0" = 0 × 2^5 = 0
Decimal equivalent of "0" = 0 × 2^6 = 0
Decimal equivalent of "1" = 1 × 2^7 = 128
Next you want to add all the products you just got to get the decimal equivalent of 10000010
0 + 2 + 0 + 0 + 0 + 0 + 0 + 128 = 130
Therefore the binary number 10000010 in decimal is 130

√-1 is imaginary number iStep-by-step explanation:
Step 1: Define function
k(x) = -5x² - 125
Step 2: Find roots
Set function equal to 0: 0 = -5x² - 125Factor out -5: 0 = -5(x² + 25)Divide both sides by -5: 0 = x² + 25Subtract 25 on both sides: -25 = x²Rewrite: x² = -25Square root both sides: x = ±√-25Rewrite: x = √-1 · ±√25Evaluate: x = ±5iwhen solving the equation 5x-3=5, MaReeco rewrote the equation as 5x =2.Did MaReeco perform an acceptable move to this equation? why or why not?
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex]5x-3=5[/tex]
MaReeco's rewrote equation is given by
[tex]5x = 2[/tex]
As MaReeco subtracted 3 to the right side of the equation, which imbalanced the equation. Hence, it is not correct.
Correction:
For the next step, MaReeco should have added 3 to both sides
i.e.
[tex]5x-3+3=5+3[/tex]
[tex]5x=8[/tex]
Therefore, the acceptable move would have been:
[tex]5x=8[/tex]Simplify the expression using order of operations.

Two hot air balloons.
Balloon one: starts at 30 miles from town and after 2 hours, it is 48 miles
Distance of Tasha's balloon is represented by function y = 8x + 20
x is independent variable so it would represent the time.
y is dependent so it represents the miles travelled.
Balloon one = (0, 30) <-- begins here and (2, 48)
Balloon two = (0, 20).
So balloon one began at 30 miles while tasha's balloon began at 20 miles from town.
So Henry's balloon was farther form the town at the beginning.
Now let's find the slope/rate of change and compare then.
Henry's balloon: y-y1/x-x1 = 48-30/2 = 18/2 = 9
Tasha's balloon m: 8
9>8 Therefore henry was faster

What they are asking for here is where the y-values are negative in interval format. Intervals are x things only, no y's allowed. So the interval of (-infinity, -3) indicates an x value of negative infinity to an x value of -3. The y's are negative from an x value of negative infinity to an x-value of -3, then again from an x value of almost -1 to an x value of almost positive 1. So your choice is the last one listed there.
