a graphing calculator is more accurate then graphing by hand especially when you dont know the exactly were the point is

Answer:

a graphing calculator is just easier to graph the points than having to put every point on a piece of graph paper. the calculator also can tell you a bunch of other things like the domain or range or y intercept or x intercept. it’s just all along easier

Answer:

y = -2/7x - 27/7

Step-by-step explanation:

first find the slope of the line -7x + 2y = 14 by solving for 'y'

2y = 7x + 14

y = 7/2x + 7

since the slope is 7/2 then the line that is perpendicular will need the opposite and reciprocal of 7/2 which is -2/7

knowing the slope ('m') and having the point (4, -5) we can find the y-intercept of the new line ('b')

y = mx + b

-5 = (-2/7)(4) + b

-5 = -8/7 + b

[change -5 into -35/7]

-35/7 + 8/7 = b

b = -27/7

put 'm' and 'b' into y = mx + b

y = -2/7x - 27/7

The required cross-sectional area in a wireway is 12.8 In squared.

The percentage is defined as a ratio expressed as a fraction of 100.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

We have been given an 8"×8"×6' long wireway the conductors can occupy.

Since the NEC permits 20% of the cross-sectional area in a wireway to be occupied by conductors

So the required cross-sectional area in a wireway is

⇒ 20 % of ( 8"×8" )

⇒ 0.20 × (64 )

⇒ 12.8 In squared

Thus, the required cross-sectional area in a wireway is 12.8 In squared.

Answer:

B. 128

Step-by-step explanation:

so the sum of the interior angle is 180

180 - 76 is 104

since both sides are the same divide 104 with 2 to get 52

to find x = 180 - 52 = 128

Answer:

Step-by-step explanation:

I = 180-152-7 = 21°

Law of Sines:

g = h·sinG/sinH ≅ 38.5 cm

i = h·sinI/sinH = 29.4 cm

Use Heron's Formula to calculate the area from the lengths of the sides.

semi-perimeter s = (g+h+i)/2 ≅ 39.0 cm

area = [tex]\sqrt{s(s-g)(s-h)(s-i)}[/tex]≅ 69 cm²

The algebraic expression of Nine less than the product of four and a number is 4x-9.

An expression is combination of variables, numbers and operators.

The given sentence is 'Nine less than the product of four and a number.

We need to write this sentence as an algebraic expression.

We know that less than means there we used subtraction.

Product in the sentence means multiplication.

Let us consider x as the unknown number in the given expression.

the product of four and a number means four is multiplied with x. which is 4x.

Nine less than the product of four and a number

4x-9

Hence, the algebraic expression of Nine less than the product of four and a number is 4x-9.
