−|−37| = 37 true or false
Answer:
false
Step-by-step explanation:
The value of |−37| is 37
however, since the negative sign is in front of the absolute value,
−|−37| = -37
Therefore,
−|−37| does not equal 37
The given statement −|−37| = 37 is false.
Given that, −|−37| = 37.
We need to whether the given statement is true or false.
What is an absolute value?The absolute value of a variable x is represented by |x| which is pronounced as 'Mod x' or 'Modulus of x'. 'Modulus' is a Latin word, which means 'measure'. Absolute value is commonly referred to as numeric value or magnitude. The absolute value represents only the numeric value and does not include the sign of the numeric value. The modulus of any vector quantity is always taken as positive and is its absolute value.
Now, |−37|=37
So, -|−37|=-37
Therefore, the given statement is false.

Find the angle between the given vectors to the nearest tenth of a degree.
u = <-5, 8>, v = <-4, 8>
2.7°
-7.3°
5.4°
15.4°
9514 1404 393
Answer:
(c) 5.4°
Step-by-step explanation:
We can simply determine the difference between the angles of the vectors:
arctan(8/-5) -arctan(8/-4) = 122.005° -116.565° = 5.440°
The angle between the vectors is about 5.4°.
__
Alternate solutions
1) We could also determine the angle of their ratio.
u/v = (-5 +8i)/(-4 +8i) = (-5 +8i)(-4 -8i)/(4² +8²) = (84 +8i)/80 = 1.05 +0.1i
angle = arctan(0.1/1.05) = 5.440°
__
2) Tan(a-b) = (tan(a)+tan(b))/(1 -tan(a)(tan(b))
tan(∠u -∠v) = ((tan(∠u) -tan(∠v))/(1 +tan(∠u)tan(∠v))
= (-1.6 -(-2))/(1 +(-1.6)(-2)) = 0.4/4.2
∠u -∠v = arctan(2/21) = 5.440°

Directions: For a spinning amusement park ride, the velocity v in meters per second of a car moving around a curve with a radius r meters is given by the formula v= √ar, where a is the car’s acceleration in m/s2.
1. For safety reasons, a ride has a minimum acceleration of 39.2 m/s2. If the cars on the ride have a velocity of 14 m/s what is the smallest radius that any curve on the ride may have?
2. What is the acceleration of a car moving at 8m/s around a curve with a radius of 2.5m?
Answer:
1. r = 5 m 2. a = 25.6 m/s²
Step-by-step explanation:
The relation between the velocity, the radius of path and the acceleration on the circular path is given by :
[tex]a=\dfrac{v^2}{r}[/tex]
1. Acceleration, a = 39.2 m/s²
Velocity of the car, v = 14 m/s
The radius of the path can be calculated using the above formula i.e.
[tex]r=\dfrac{v^2}{a}\\\\r=\dfrac{(14)^2}{39.2}\\\\r=5\ m[/tex]
2. Velocity of the car, v = 8 m/s
The radius of the path, r = 2.5 m
The acceleration of the car is given by :
[tex]a=\dfrac{8^2}{2.5}\\\\a=25.6\ m/s^2[/tex]
Hence, this is the required solution.

The volume of a cereal box is 264 in3 . If it has a width equal to 3 inches and length of 8 inches, what is the height?
Answer:
11 inches
Step-by-step explanation:
Volume of a box is:
[tex]l * w * h[/tex]
[tex]8 * 3 * h = 264\\\\24*h=264\\\\\frac{24*h=264}{24} \\\\\boxed{h=11}[/tex]
The height is 11 inches.
Hope this helps.
Volume of the box = LWH.
Let V = 264
264 = (8)(3)(H)
264 = 24H
264 ÷ 24 = H
11 = H
The height of the box is 11 inches.

A story owner wants to prepare 100 lb of a candy mix that she will she for $1.36 per lb. She mixes 20 lb of jelly beans that cost 20 cents per lb with sugar candies. How much does 1 lb of sugar candies cost?
Answer:
1.65
Step-by-step explanation:
100 pounds of the mixture = 1.36 * 100 = 136 dollars.
She uses 20 pounds of jelly beans that cost
20 * .20 = 4.00
136 - 4 = 132 dollars left for 80 pounds of sugar candies.
80 pounds = 132 pounds of sugar candies.
1 pound = x
80/1 = 132 / x Cross multiply
80x = 132
x = 132 / 80
x = 1.65 / per pound

Answers:
6) b. Apply square root to both sides7) d. 8 by 10. 8) a. Thickness of edge that leads to total area of 100 square inches9) a. x = -5 and x = 3/210) d. zero product property======================================================
Explanations:
6) We apply the square root to both sides to undo the squaring operation.7) The photo without the frame is 8 by 10 since we add on two copies of x to jump from 8 to 8+2x. Similarly, we go from 10 to 10+2x.8) The x represents the thickness of the frame. The 100 is the total area (picture + frame). The expression on the right hand side is also the total area.9) Apply the zero product property to set each factor equal to zero. You'll find that x+5 = 0 leads to x = -5. Also, 2x-3 = 0 becomes 2x = 3 and solves ultimately to x = 3/210) Refer to problem 9Find the area use 3.14 for the value of pi

The average test score for 8 students is 5 the scores for 7 of the 8 students are shown what is the score of the 8th student
Answer:
70
Step-by-step explanation
Find the diagram attached
Average = Sum of scores/sample size
Given the 7 numbers
20, 20, 20, 30, 80, 80, 80
Average = 50
5 = 20+20+20+30+80+80+80+x/8
x is the score of the 8th student
50 = 330+x/8
400 = 330+x
x = 400-330
x = 70
Hence the score of the 8th student is 70

Hence the percent increase is
% increase= Change/ initial*100
% increase= 7/47*100
% increase=0.148*100
% increase=14.8%

Distribute (2m-5m)(-5)
First Method (Distributive Property)
(2m - 5m) (-5)
Rearrange the equation to make it easier.
(-5) (2m - 5m)
In distributive property, it's all about multiplying. The -5 goes to the 2m and the 5m. Like this: (-5 • 2m) - (-5 • 5m).
-10m + 25m
15m
Second Method
(2m - 5m) (-5)
Since 2m and 5m have the same variable, we can subtract them.
(-3m) (-5)
Multiply.
15m
15m is your answer. I hope this helps!
