9) The speed limit on the freeway is 65 miles per hour. a) What is this speed in kilometers per minute?
b) If you drive for 3.5 hours at the speed limit? How many kilometers have you travelled?
Answer: Answer is in the steps
Step-by-step explanation:
A) First convert 65 miles to kilometers
65 miles to kilometers is 104.607
Convert 1 hour to minute and that will be 60 minutes because 60 minutes makes and hour.
Now divide the kilometers by the number of minutes
104.607 / 60 = 1.74345
The speed will be 1.74345 kilometers per minute.
B) Convert 3.5 hours to minutes.
3.5 hours is the same as 210 minutes
Now multiply it by 1.74345 to determine how many kilometers you have traveled.
1.74345 * 210 = 366.1245
You will travel 366.1245 kilometers in 3.5 hours.

Urgent ! Use a table to compress the function y=f(x) vertically by 1/2 . Identify the graph of the function and its transformation . A-B-C- or D ?
The third one is the right answer
Answer:
The first one is right. (A)
Step-by-step explanation:
Whenever we talk about compressions we just need to compress one of the axes in this case we are asked to compress the y-axis which means that the only values that will change are the y-values, don't get confused the x values have to stay the same.

Steve had 48 chocolates but decided to give 8 chocolates to each of his coworkers. How many chocolates does Steve have left? Write your answer as an expression.
Answer:
y = 48 - (8x)
Step-by-step explanation:
x = unknown number of coworkers
y = number of chocolates left over
y = 48 - (8x)
Example: If you were to plug in the number 5 for x:
y = 48 - (8(5))
y = 48 - 40
y = 8
The answer is 48-8f

∘
. Find \text{m}\angle NLM.m∠NLM
Answer:
[tex]\bold{\angle NLM = 10^\circ}[/tex]
Step-by-step explanation:
Given a ΔLMN.
Line LN is extended to point O.
such that:
[tex]\text{m}\angle MNO = (5x-13)^{\circ}[/tex]
[tex]\text{m}\angle NLM = (x-4)^{\circ}[/tex] and
[tex]\text{m}\angle LMN = (2x+19)^{\circ}[/tex]
To find:
[tex]\text{m}\angle NLM=?[/tex]
Solution:
Kindly refer to the attached image for the given triangle and dimensions of angles.
Let us recall the external angle property of a triangle:
The external angle of a triangle is equal to the sum of two opposite internal angles.
i.e.
[tex]\angle MNO = \angle NLM + \angle LMN\\\Rightarrow 5x-13 = x-4+2x+19\\\Rightarrow 5x-13 = 3x+15\\\Rightarrow 5x-3x = 13+15\\\Rightarrow 2x=28\\\Rightarrow x =14[/tex]
Putting the value of [tex]x[/tex] in [tex]\angle NLM[/tex].
[tex]\angle NLM=14-4 \\\Rightarrow \bold{\angle NLM = 10^\circ}[/tex]
please someone help me... i need full answer
Answer: see proof below
Step-by-step explanation:
Use the following Sum to Product Identities:
[tex]\sin x-\sin y=2\cos\bigg(\dfrac{x+y}{2}\bigg)\sin\bigg(\dfrac{x-y}{2}\bigg)\\\\\\\cos x-\cos y=2\cos\bigg(\dfrac{x+y}{2}\bigg)\cos\bigg(\dfrac{x-y}{2}\bigg)[/tex]
Proof LHS → RHS
[tex]\text{LHS:}\qquad \qquad \qquad \qquad \dfrac{\sin 2A+\sin 5A-\sin A}{\cos A+\cos 2A+\cos 5A}[/tex]
[tex]\text{Regroup:}\qquad \qquad \qquad \dfrac{\sin 2A+(\sin 5A-\sin A)}{\cos 2A+(\cos 5A+\cos A)}[/tex]
[tex]\text{Sum to Product:}\qquad \dfrac{\sin 2A+2\cos\bigg(\dfrac{5A+A}{2}\bigg)\sin\bigg(\dfrac{5A-A}{2}\bigg)}{\cos2A+\cos\bigg(\dfrac{5A+A}{2}\bigg)\cos\bigg(\dfrac{5A-A}{2}\bigg)}[/tex]
[tex]\text{Simplify:}\qquad \qquad \qquad \dfrac{\sin 2A+2\cos 3A\sin 2A}{\cos 2A+2\cos 3A\cos 2A}[/tex]
[tex]\text{Factor:}\qquad \qquad \qquad \dfrac{\sin 2A(1+2\cos 3A)}{\cos 2A(1+2\cos 3A)}[/tex]
[tex]\text{Simplify:}\qquad \qquad \qquad \dfrac{\sin 2A}{\cos 2A}\\\\.\qquad \qquad \qquad \qquad =\tan 2A[/tex]
LHS = RHS: tan 2A = tan 2A [tex]\checkmark[/tex]

The value of the modulus function is A = 18
What is Modulus Function?Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.
It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.
The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:
If x is positive, then f(x) = x
If x = 0, then f(x) = 0
If x < 0, then f(x) = -x
Given data ,
Let the modulus function be represented as A
Now , the value of A is
A = 6 | 5 - c | + 2c be equation (1)
Now , when the value of c = 6
Substituting the value of c in the equation , we get
A = 6 | 5 - 6 | + 2 ( 6 )
A = 6 | -1 | + 2 ( 6 )
The value of the modulus function always returns a positive value ,
So , A = 6 ( 1 ) + 2 ( 6 )
A = 6 + 12
A = 18
Therefore , the value of A is 18
Hence , the modulus function is A = 18

Select the correct choice that completes the sentence below -5(x-3) = -5x +15 illustrates the ____ property of multiplication over addition 1. Additive 2. Inverse 3. Distributive 4. Commutative 5. Multiplication
Answer: 3. Distributive
Step-by-step explanation:
Distributive property of multiplication over addition is the only property that is require to multiply an expression to the other expression with two or more than two terms.
For example: a (b+c)= a b+ac , where a,b,c can be any expression.
Given expression: -5(x-3) = -5x +15 , which illustrates the distributive property of multiplication over addition.
Hence, the correct option is 3. Distributive.
The rest of properties cannot work for multiplication over addition as they are used for one operation.
Suppose two quantities, A and B, have different dimensions. Determine which of the following arithmetic operations could be physically meaningful.
a. B-A
b. A-B
c. A+B
d. AB
e. A/B
Answer:
d. AB
e. A/B
Step-by-step explanation:
From the concept of homogeneity of dimension. The principle is that if two quantities occurs in the same direction, addition and subtraction of those two variable tends to occur but if two quantities occur in different direction, then we can only have either the division and multiplication of those quantities.
From the given information;
Suppose two quantities, A and B, have different dimensions.
The arithmetic operations that could be physically meaningful are :
d. AB
e. A/B

Use the figure shown to the
right to write a polynomial
that represents the areatof
the shaded region. Express
the polynomial in standard
form, that is, in descending
powers of x.
The polynomial that represents the area of the shaded region is ]
(Simplify your answer. Type your answer in standard form.)
Answer:
4x + 16
Step-by-step explanation:
The area of the shaded region = area of the outer rectangle - area of the inner rectangle
Area of rectangle = l*w
Area of outer rectangle, where length (l) = (x + 5), and width (w) = (x + 4):
Area = (x + 5)(x + 4)
Expand
x(x + 4) +5(x + 4)
x² + 4x + 5x + 20
area of outer rectangle = x² + 9x + 20
Area of inner rectangle, where length (l) = (x + 4), and width (w) = (x + 1):
Area = (x + 4)(x + 1)
Expand
x(x + 1) +4(x + 1)
x² + x + 4x + 4
Area of inner rectangle = x² + 5x + 4
Area of shaded region = (x² + 9x + 20) - (x² + 5x + 4)
x² + 9x + 20 - x² - 5x - 4
Collect like terms together
x² - x² + 9x - 5x + 20 - 4
4x + 16
Area of the shaded region = 4x + 16

factor (difference of squares) the binomial 25x^2-4 and find one of its factors
Step-by-step explanation:
Hey, there!
Here,
Given that:
[tex] = 25 {x}^{2} - 4[/tex]
we need to find factor,
As it is in a^2-b^2 form as per its factor (a+b) (a-b), keeping same formula here,
25x^2 means (5x)^2
and 4 means 2^2
Now, it would be,
[tex] = ( {5x)}^{2} - {2}^{2} [/tex]
[tex] = (5x + 2)(5x - 2)[/tex]
Therefore, it's factor would be (5x+2)(5x-2).
