What Value For A Would Make The Equation True? Type In Only The Numerical Answer Or Value.

Answers

Answer 1

Answer:

a = 3

Step-by-step explanation:

Here you can use the cross multiplication strategy or whatever it's called. That's where you multiply the diagonals together. Its kinda long to explain, but you can google it for details.

In either case, you get the following equation:

8(2a-1) = 4(a+7)

Open the parenthesis

16a - 8 = 4a + 28

Subtract 4a from both sides

12a - 8 = 28

Add 8 to both sides

12a = 36

Divide both sides by 12

a = 3

Carlos wants to send Cecil a message encrypted with RSA. Cecil has published his public encryption exponent $5$ and his public modulus $133$. When Carlos encrypts the number $3$ with this system, what is the result is to be determined.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements.

Here,
Encrypt message M = 3
Public key = (133, 5)
When [tex]M^e[/tex] = [tex]3^5[/tex] = 243 divided by 133 gives the remainder of C = 110,

Thus, the required result from the encryption of the number $3$ is 110.

Step-by-step explanation:

f(x) is defined as 3x + 1.  To find f(g(x)), substitute g(x) = 3x for x in f(x):

f(g(x)) = 3(g(x)) + 1 = 3(3x) + 1 = 9x + 1

What is the slope of the line containing the points (5,-8)
and (-5,8)?

Answers

Answer: m = -⁸⁄₅

PLz mark brsinliest:)

The slope of the line containing the points (5,-8) and (-5,8) is -8/5 after using the concept of the slope of a line.

What is the slope?

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that:

The line containing the points (5,-8) and (-5,8)

A straight line is a combination of endless points joined on both sides of the point.

As we know from the formula of the slope:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\rm m =\dfrac{8-(-8)}{-5-5}[/tex]

m = (8 + 8)/(-10)

m = -16/10

m = -8/5

Thus, the slope of the line containing the points (5,-8) and (-5,8) is -8/5 after using the concept of the slope of a line.

2. In square MISA, the diagonals intersect at point P. If m_MPA

= (2s + 3t)º, MZISP = (4r + s)° and m_MIS = (3s – 2t)º, find

the values of r, s, and t.

Answers

The diagonal of the square MISA bisect the angle at the vertices

The values of r, s and t are r  = 2.6, s = 34.6 and t = 6.9

How to determine the values of r, s and t?

The given parameters are:

MPA = (2s + 3t)º

ISP = (4r + s)°

MIS = (3s – 2t)º

The angle between the diagonal of a square is 90 degrees.

So, we have:

2s + 3t = 90

Multiply by 2

4s + 6t = 180

The angle at the vertices of the square is 90 degrees.

So, we have:

3s - 2t = 90

Multiply by 3

9s - 6t = 270

The diagonal bisect the angle at the vertex.

So, we have:

4r + s = 45

Rewrite the equations

4s + 6t = 180

9s - 6t = 270

4r + s = 45

Add the first and the second equations

4s + 9s + 6t - 6t = 180 + 270

13s= 450

Divide by 13

s = 34.6

Substitute s= 34.6 in 4r + s = 45 and 3s - 2t = 90

4r + 34.6 = 45

Solve for r

r  = 2.6

3 * 34.6 - 2t = 90

Solve for t

t = 6.9

Hence, the values of r, s and t are r  = 2.6, s = 34.6 and t = 6.9

Answers

2.68
Subtract 8.28 and 5.6 to get y then plug the answer in to check your work!

Answer:

Y = 2.68

Step-by-step explanation:

Y + 5.6 = 8.28

To find Y, you would need to subtract 5.6 from both sides:

Y + 5.6 - 5.6 = 8.28 - 5.6

So that would simplify to:

Y = 8.28 - 5.6

8.28 - 5.6 = 2.68

So Y = 2.68

Luna went over to a friend's house to play. She arrived at her friend's house at 9:23 A.M. and went back home at 2:06 P.M. How long did Luna stay at her friend's house?

Answers

Step-by-step explanation:

AM switches to PM at 12 PM.

so, we need to calculate the time from 9:23 am to 12 pm, and then from 12 pm to 2:06 pm, and then add both for the overall answer.

the first full hour after 9:23 am is 10 am. from there it is 2 hours to 12 pm.

how many minutes from 23 minutes to 60 (of the next full hour) ? 60 - 23 = 37 minutes.

so, it is 2 hours and 37 minutes until 12 pm.

and from 12 pm to 2:06 pm it is 2 hours and 6 minutes.

the total time is then

2 hours 37 minutes + 2 hours 6 minutes =

= 2 + 2 hours 37 + 6 minutes = 4 hours 43 minutes

FYI

if the sum of the minutes would have been larger than 60 (like e.g. 53 + 12), then we would have had to add another hour as a carry over, and take the remainder of minutes/60 as minutes.

e.g.

2 hours 53 minutes

3 hours 12 minutes

would sum up to

5 hours 65 minutes = 6 hours 5 minutes

Answers

It would take about 1.94 seconds for the soccer ball to hit the ground.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Let h represent the height of the soccer ball after time t, hence:

h(t) = -16t² + 30t + 2

The soccerball hits the ground when h = 0, hence:

0 = -16t² + 30t + 2

t = 1.94 seconds

this is because if the left side is 23 and part of the left side is 13 the leftover part is 10

then the bottom is 13 by 26

Open the bracket

101 - 6+ 2 = 12x - 4 - 2

Collect the like terms

12x = 101 - 6+ 2 + 4 + 2

Evaluate the like terms

12x = 103
