How do we Round with any numbers, (on a number line) ?

Answers

Answer 1

Answer:

round it to the nearest 10th?

Step-by-step explanation:

that's what I do at least.

Answer 2

Answer: Round up or down.

Step-by-step explanation: When you round up, look at the number to the right of the number you wanna round. If it’s less than 5, you round down, if it’s more than 5, you round up. On a number line, for ex. Let’s say you wanna round 550 to hundreds, 600 or 500, 600 would be the answer because 550 is more closer to 600 by default.

Given g(x)=−2x2+1, find the indicated values: g(-4)

Answers

g(-4) means inputing -4 into x. So you will be replacing x with -4 in order to find a y for that input (-4). So...

g(-4)=-2(-4)^(2) + 1
=8^2 +1

What value of n makes the equation true?

Answers

Answer:

n=10

Step-by-step explanation:

You need n to be 10 because: y^20= (y^10)^2

Answer:

n = 10

Step-by-step explanation:

(2x⁹yⁿ) * (4x²y¹⁰) = 8 x¹¹ y²⁰

use the rules of exponents to simplify the expression.

2¹ x⁹ yⁿ * 4¹ x² y¹⁰

use the commutative property of multiplication

2¹ * 4¹ x⁹ x² yⁿ y¹⁰

add exponents of the same base:

8 x⁹ ⁺ ²  y ⁿ ⁺ ¹⁰

back to original equation:

8 x⁹ ⁺ ²  y ⁿ ⁺ ¹⁰ =  8 x¹¹ y²⁰

therefore

the value of n = 10


Consumers are paying record amounts of fees for overdrawing their bank accounts. In 2007, bankes this and credit unions collected $649 on in overdraft fees, which is $144 on more than in 2001. What is the
percent of increase?

Answers

Answer: 1.3 percent increase (to the nearest 10th

Step-by-step explanation: to figure out the percent of increase, you have to take the $144 away from 649, which is $505, then divide so:

$649 - $144 = $505

$649 / $505 = 1.28...or ~1.3

Alvin's age is three times Elga's age. The sum of their ages is 116. What is Elga's age?
years old

Answers

Answer:

Let Elga's Age be x and Alvin's age be 3x

x + 3x = 116

4x = 116

x = 116/4

x = 29

Therefore , 3x = 3(29) = 87

Elga's Age - 29

Alvin's Age - 87

move to arrive at the next point on the graph. Write these two numbers as a fraction."
"Look at the graph of the relationship. Find the x-value of the point that corresponds to y = 2. That value is the unit
rate."

What are the quadrants of the standard (x, y) coordinate plane below that contain points on the graph of the equation 4x - 2y = 8 ?

Answers

Answer:

Step-by-step explanation:

4x-2y=8

divide by 8

[tex]\frac{x}{2}+\frac{y}{-4}=1\\x~intercept=2\\y~intercept=-4\\also ~2y=4x-8\\y=2x-4\\slope=2\\[/tex]

so graph lies in third and fourth and first quadrants.

The  graph lies in third and fourth and first quadrants.

What is graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter. Each object in a graph is called a node.

Given:

4x - 2y = 8

Now, make the equation in standard form

4x/8 - 2y/8 = 8/8

x/2- y/4 = 1

Now,

y- intercept is -4

and x- intercept is 2.

Also, we can write  4x - 2y = 8 as

y=  2x-4 and slope= 2

Hence, graph lies in third and fourth and first quadrants.

Write the expression as the sine cosine or tangent of an angle calculator.

Answers

Answer:

hello your question is incomplete here is the complete question

write the expression as the sine, cosine,  or tangent of an angle.

[tex]sin 60 cos 15 + cos 60 sin 15[/tex]

answer : [tex]sin 60 cos 15 + cos 60 sin 15 = sin 75[/tex]

Step-by-step explanation:

To write the expression as the sine,cosine or tangent of an angle we will employ the trigonometry identity

[tex]sin 60 cos 15 + cos 60 sin 15[/tex]  can be represented in the form of ;

sin( u + v ) = sin u cos v + cos u sin v --------- (1)

comparing equation 1 with the given expression

u = 60 and v = 15

therefore writing the expression in the form of the sine of an angle would be the answer

= sin( 60 + 15 )  = sin 60 cos 15 + cos 60 sin 15

hence sin ( 75 ) = sin 60 cos 15 + cos 60 sin 15

Answers

Answer:

Step-by-step explanation:

From the given information.

suppose a multiple choice test consists of 5 questions, each with 4 possible answers of which 1 is correct.:

So, we can now suggest that a person can answer each question in 4 different ways given that there are 5 different questions.

Thus, the  students can check off one answer to each question in [tex]4^5 \ different \ ways[/tex]

= 4 × 34 × 4 × 4 × 4

= 1024 different ways.

From the 4 possible answers, since 1 will be correct, definitely 3 other answers will be incorrect.

Thus, the number of ways a student can check off one answer to each question and get all the answers wrong is = 3⁵

= 3 × 3 × 3 × 3 × 3

= 243 ways
