Answer 1

Answer:

3y-x =-6

Step-by-step explanation:

The equation of a line in point slope form is expressed as;

y-y0 = m(x-x0)

(x0, y0) is the point = (3, -1)

Given the equation 3xs+y = 1

Get the slope

y = -3x + 1

mx = -3x

m = -3

Since the equation needed is perpendicular to the line, the slope will be expressed as;

M = -1/-3

M = 1/3

Substitute and get the equation needed

y-y0 = m(x-x0)

y - (-1) = 1/3(x-3)

y+1 = 1/3(x-3)

3(y+1) = x-3

3y+3 = x-3

3y - x = -3-3

3y-x =-6

This gives the required equation

using appropriate properties find 9/16×4/12+9/16×-5/9

Answers

Answer:

-1/8

Step-by-step explanation:

Given 9/16×4/12+9/16×-5/9

Using the PEMDAS rule;

Multiplication first

(9/16×4/12)+(9/16×-5/9)

= 3/4 * 1/4 + -5/16

= 3/16 - 5/16

= (3-5)/16

= -2/16

= -1/8

Hence the required answer is -1/8

The print on the package of -watt General Electric soft-white light-bulbs says that these bulbs have an average life of hours. Assume that the lives of all such bulbs have a normal distribution with a mean of hours and a standard deviation of hours. Find the probability that the mean life of a random sample of such bulbs will be

Answers

Answer:

Hi your question is incomplete attached below is the complete question

answer : p ( X < 725 ) = 0.0116

Step-by-step explanation:

Given data:

Average life of bulbs (μ ) = 750 hours

standard deviation (б ) = 55 hours

n ( sample size ) = 25

X = 725

Probability that the mean life of a random sample of 25 bulbs will be less than725 hours

p ( X < 725 ) = p (( X - μ )/ б √n < 725 - 750 / 55√25 )

= P ( Z > - 2.27 )

Hence P ( X < 725 ) = 0.0116 ( using Z-table )

For two functions, m(x) and p(x), a statement is made that m(x) = p(x) at x = 7. What is definitely true about x = 7? (2 points)

a
Both m(x) and p(x) cross the x-axis at 7.

b
Both m(x) and p(x) cross the y-axis at 7.

c
Both m(x) and p(x) have the same output value at x = 7.

d
Both m(x) and p(x) have a maximum or minimum value at x = 7.

Answers

Answer:

c. Both m(x) and p(x) have the same output value at x = 7.

Step-by-step explanation:

For input value x, m(x) is the output value.

m(7) is the output value of the function m(x) when x=7.

p(7) is the output value of the function p(x) when x=7.

The statement m(x) = p(x) for x=7 is a statement that the output values are the same at x=7.

an aquarium at the zoo is shaped like a cylinder. it has a height of 4 feet and a base radius of 2.5 feet. the aquarium is being filled with water at a rate of 12 gallons per minute. if one cubic foot is about 7.5 gallons, how long will it take the aquarium to fill? round to the nearest whole minute.

Answers

Answer:

49 minutes

Step-by-step explanation:

Volume

v = πr²h

v = π(2.5²)4

v = 78.5 ft³

PLEASE HELP ME :(. Look at this system of equations.
X - 8y = -3
5x - 2y = 4
What value of a will make this system have the same solution?
ax = -19
5x - 2y = 4

Answers

9514 1404 393

Answer:

a = -19

Step-by-step explanation:

In the first set of equations, subtract 4 times the second equation from the first.

(x -8y) -4(5x -2y) = (-3) -4(4)

-19x = -19 . . . . simplify

Comparing this to the equation ...

ax = -19

we see that they will have the same solution when a = -19.
