Answer:

  y = -1/2x -2

Step-by-step explanation:

The given line has slope 2, so the perpendicular line will have slope -1/2, the negative reciprocal of the given slope.

The y-intercept is given as -2, so the line's equation in slope-intercept form is ...

  y = mx +b . . . . line with slope m and y-intercept b

  y = -1/2x -2

One side of triangle is 5 more than 3 times the shortest side. The third side is 24 feet more than the shortest side. The perimeter is 114 . Find all three sides.

Answers

Answer:

17, 56, 41,

Step-by-step explanation:

"third side is 24 more than shortest side"

Let a be the shortest side.

c = a+24

"perimeter is 114"

a+b+c = 114

a+b+(a+24) = 114

2a + b = 90

"one side is 5 more than 3 times the shortest side"

That side must be b; c is an extraneous solution.

b = 3a+5

2a+(3a+5) = 90

a = 17

b = 56

c = 41

(a,b,c) = (17,56,41)

A triangle has an area of 29.7cm^2 and a base of 13.5cm. Use the formula A=1/2 bh to find the height.

Answers

Answer:

4.3362962963

Step-by-step explanation:

A=1/2bh

29.7cm^2=1/2 13.5h

You're gonna multiply each side by 2 to cancel out the fraction equaling,

58.54= 13.5h

You're then gonna divide w=each side by 13.5 to get h left alone on one side and a number on the other equaling your answer. 4.3362962963. Round to whatever decimal place you need.

Find the perimeter of the triangle whose vertices are the following, specified points in the plane.
(-10,-3), (1,4) and (-1,7)

Answers

Given:

The vertices of the triangle are (-10,-3), (1,4) and (-1,7).

To find:

The perimeter of the triangle.

Solution:

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Let the vertices of the triangle are A(-10,-3), B(1,4) and C(-1,7).

Using distance formula, we get

[tex]AB=\sqrt{(1-(-10))^2+(4-(-3))^2}[/tex]

[tex]AB=\sqrt{(1+10)^2+(4+3)^2}[/tex]

[tex]AB=\sqrt{(11)^2+(7)^2}[/tex]

[tex]AB=\sqrt{121+49}[/tex]

[tex]AB=\sqrt{170}[/tex]

Similarly,

[tex]BC=\sqrt{\left(-1-1\right)^2+\left(7-4\right)^2}=\sqrt{13}[/tex]

[tex]AC=\sqrt{\left(-1-\left(-10\right)\right)^2+\left(7-\left(-3\right)\right)^2} =\sqrt{181}[/tex]

Now, the perimeter of the triangle is

[tex]Perimeter=AB+BC+AC[/tex]

[tex]Perimeter=\sqrt{170}+\sqrt{13}+\sqrt{181}[/tex]

[tex]Perimeter\approx 13.038+3.606+13.454[/tex]

[tex]Perimeter=30.098[/tex]

Therefore, the perimeter of the triangle is 30.098 units.

Hello friend in which question do you want to help

. A system may become infected by some spyware through the internet or e-mail. Seventy percent of the time the spyware arrives via the internet, thirty percent of the time via email. If it enters via the internet, the system detects it immediately with probability 0.6. If via e-mail, it is detected with probability 0.8. What percentage of times is this spyware detected

Answers

Answer:

This spyware is detected 66% of the time.

Step-by-step explanation:

We have these following percentages:

70% of the time, the spyware arrives via the internet, and in this case, is detected 60% of the time.

30% of the time, the spyware arrives via e-mail, and in this case, is detected 80% of the time.

What percentage of times is this spyware detected

Sum of 60% of 70%(arrived via spyware, detecte) and 80% of 30%(arrive via e-mail, detected). So

[tex]0.6*0.7 + 0.8*0.3 = 0.42 + 0.24 = 0.66[/tex]

This spyware is detected 66% of the time.

consider the inequalities
y 2x + 3, which is true?

a. the line would be solid with shading above

b. the line with be duchess with shading above

c. the line would be solid with shading below

d. none of this

please answer this guys:-(

Answers

Answer:

The line with be duchess with shading below.

None of the above

Step-by-step explanation:

The correct inequality expression is;

y < 2x+3

Note that the inequality sign between the expressions is the one that will determine the nature of the line.

Since the sign is not containing the "equal to" sign this means that the line will be broken(duchess).

Since it is "less than", the shading will be below the line.

Considering the given option, None of the option is correct

For the inequalities

[tex]\rm\bold{ y < 2x+3 ......(1)} \\\\\rm \bold{y > 2x +3....(2)}}[/tex]

For Case (1)

Option d will be chosen as correct option

hence " none of these" will be the answer  

For Case (2)

Option b will be chosen as correct option

hence " The line with be duchess with shading above " will be the answer  

Since the sign of the inequality here is not clear let us consider 2 cases that are represented by equation (1) and equation (2)

[tex]\rm y < 2x+3 ......(1) \\y > 2x +3....(2)[/tex]

Considering case 1 as represented by equation (1)

The y values are always less than the expression for the line 2x+3 hence points on the line [tex]\rm y = 2x +3[/tex] will not be included for this inequality hence the line will be duchess with area below the line.

So in this case option d will be chosen as correct option

hence " none of these" will be the answer  

Similarly now considering case 2 as  represented by equation (2)

The y values are always more than the expression for the line 2x+3 hence

points on the line [tex]\rm y = 2x +3[/tex] will not be included for this inequality hence the line will be duchess with area above the line.

So in this case option b will be correct.

Note :

The lines will be solid when  the inequalities in equation (1) and (2) also include equal to sign.

That is for lines to be solid

the inequalities will be of type

[tex]\rm y \leq 2x+3 \\y \geq 2x +3[/tex]
