Determine the values of m in the equation m2 = 16.
answers are
m = ±4
m = 4
m = ±8
m = 8
Answer:
I'll assume m2 is m^2
m = ±4
Step-by-step explanation:
1. m = ±4 m^2 = 16 YES. Both -4 and 4, when squared, are equal to 16
2. m = 4 This also works, but it doiesn't allow for the possibility that m is a -4
3. m = ±8 8^2 = 64 and (-8)^2 = 64 Don't work.
4. m = 8 8^2 = 64 Doesn't work.
Which is an equivalent expression using a positive exponent?
(3/5)^-8 ÷ (3/5)^-4
(3/5)^4
(3/5)^12
(5/3)^32
(5/3)^4
The equivalent expression using a positive exponent is (5/3)⁴ .
If an expression was created utilizing integer variables, constants, and algebraic operations, it is said to be algebraic (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number)
However, since they are not produced by using integer constants and algebraic operations, transcendental numbers like such and e are not algebraic. The production of is commonly stated as a geometric expression, although the definition of e requires an infinite number of algebraic operations.An expression is said to be rational if it can be reduced to an acceptable fraction using the characteristics of arithmetic operations (commutative properties and associative properties of addition and multiplication, distributive property and rules for the operations on the fractions).A positive expression is given as (3/5)⁻⁸ ÷ (3/5)⁻⁴ .
Using the properties of exponents we can calculate the expression as:
(3/5)⁻⁸⁺⁴ = (3/5)⁻⁴ = (5/3)⁴
Hence the required expression is (5/3)⁴

Liam buys some fruit for £26.55.
He pays the exact amount using two notes and four coins.
List the notes and coins Liam could have used.
Answer:
£20 note, £5 note, 50p,50p,50p, 5p
Step-by-step explanation:
Liam buys some fruit for £26.55 by paying 2 notes of £20 and £5 and 3 coins of 50 cent and one coin of 5 cent.
What is addition?Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.
Given:
Liam buys some fruit for £26.55.
He pays the exact amount using two notes and four coins.
So, possible notes are £1, £5, £10 and £20.
And the possible coins are 1¢, 5¢, 10¢, 25¢, 50¢, and £1.
So, through trial and error,
we get notes of £20 and £5.
And the coins are three coins of 50 cent and 1 coin of 5 cent.
The total amount = adding the amount of notes and coins.
£26.55 = £20 + £5 + 3(50¢) + 5¢
Therefore, notes of £20 and £5 and the coins are three coins of 50 cent and 1 coin of 5 cent, Liam used.

A straight road makes an angle of 15 degrees with the horizontal. When the angle of elevation of the sun is 57 degrees, a vertical pole at the side of the road casts a shadow 75 feet long directly down the road, as shown in the figure. Approximate the length of the pole. Round to the nearest hundredth.
The length of the pole is 19.15 feet.
What is the angle of elevation?The angle of elevation is created by the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, the angle formed is an angle of elevation.
Given:
Angle made by straight road = 15°
Angle of elevation of the sun = 57°
Length of the shadow = 75 feet
∠ACB = 90° - 57° = 33°
∠CAB = 57° - 15° = 42°
Using Sine Law to find BC i.e.length of the pole.
[tex]\frac{BC}{sin A} = \frac{AB}{sin C}[/tex]
[tex]\frac{BC}{sin 42} = \frac{75}{sin 33}[/tex]
[tex]BC= \frac{75sin 42}{sin 33}[/tex]
BC ≅ 19.15 feet (to the nearest hundredth.)
Therefore, the approximate length of the pole is 19.15 feet.

Write a function to represent the data.
The data in the question will be represented by a geometric sequence given by 3 (2) ⁿ⁻¹.
A geometric sequence is defined as the sequence in which the ratio between the consecutive terms of the sequence remains constant. The ratio is known as common ratio. The nth term of geometric sequence is written as a (r)ⁿ⁻¹ where a is the first term, r is the common ratio and n is the number of terms. We know from the question that the time in minutes Aurora takes to complete the task forms a sequence as 3, 6, 12, 24.....

Some information is given about each sphere. Order them from least volume to greatest volume. You may sketch a sphere to help you visualize if you prefer. Sphere A: Has a radius of 4 Sphere B: Has a diameter of 6 Sphere C: Has a volume of 64 Sphere D: Has a radius double that of sphere B.
The least volume to greatest volume will be sphere B, sphere C, sphere A and sphere D.
What will be the volume of the sphere?The volume of the sphere is calculated as:
= 4/3 πr³
where r = radius
The volume of sphere A will be:
= 4/3 πr³
= 4/3 × π × 4³
= 85.3π
The volume for sphere B will be:
= 4/3 πr³
= 4/3 × π × (6/2)³
= 4/3 × π × 3³
= 36π
The volume for C is given as 64π.
The volume for D has a radius double that of B. This will be Radius = 3 × 2 = 6
= 4/3 πr³

Solve the inequality algebraically x^2+10x+9<0
Answer:
−9 < x < −1
Step-by-step explanation:
a) Let's find the critical points of the inequality.
x^2 + 10x + 9 = 0
(x + 1)(x + 9) = 0
x + 1 = 0 or x + 9 = 0
x = −1 or x = −9
x < −9 (Wrong)
−9 < x < −1 (Correct)
x > −1 (Wrong)
Your answer is −9 < x < −1

Is there a dilation that maps shape I onto shape II? If so, what is the scale factor and is it an enlargement or a reduction?
Give me the actual answer, not explanation, for 10 points
The scale factor for the graph will be 3 and there will be enlargement.
The scale factor may be defined as the ratio of two dimensions such that one figure is large, and another is small. The scale factor is done due to the unpractical measurement of any figure. For example, if a figure is a scale copy of the scale factor of 6/2 it means 2 is converted into 6. We can use the following points to know about enlargement.
A(1, 1) ⇒ A'(3, 3)
B(2, 1) ⇒ B'(6, 3)
C(1, 2) ⇒ C'(3, 6)
D(2, 2) ⇒ D'(6, 6)
Now, to find the scale factor, simply divide the Point' with the original Point. Use any number.
A'(3, 3)/(A(1, 1)) = 3
B'(6, 3)/(B(2, 1)) = 3
C'(3, 6)/(C(1, 2)) = 3
D'(6, 6)/(D(2, 2)) = 3
which shows that the scale factor is 3.

The percentage of students in Brookland Middle School who are attending seventh grade is 54.54%
What is percentage?
In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100. Although "pct," "pct," and occasionally "pc" are also used as abbreviations, the percent symbol "%" is most usually used to denote it. A% is a number that has no dimensions and is dimensionless (pure).
We know that, to get the value of percentage we have to divide the value for which percentage needs to be calculated by total value and then multiply the resultant by 100.
So, we will divide the number of student in seventh class by the total number of student and then multiply it with 100.
(750/1375)100 = 54.54 %
Therefore, percentage of students attending Brookland Middle School are in seventh grade is 54.54%.

Answer:
[tex]x=0, \quad x=-7[/tex]
Step-by-step explanation:
Given equation:
[tex]x^2+7x=0[/tex]
Factor x from the left side of the equation:
[tex]\implies x(x+7)=0[/tex]
Using the Zero Product Property, set each factor equal to zero and solve for x:
[tex]\implies x=0[/tex]
[tex]\implies x+7=0 \implies x=-7[/tex]
Therefore, the solutions of the equation are:
[tex]x=0, \quad x=-7[/tex]
Zero Product Property: If a⋅b = 0 then either a = 0 or b = 0 (or both).
