Answer:

Slope (m) = \frac{y}{x} = \frac{2}{3} = 0.66666666666667

Step-by-step explanation:

0 = arctan (\frac{y}{x}) = 33.69006752598°

X = 4 – 1 = 3

Y = 4 – 2 = 2

Distance (d) = \sqrt{x^2+y^2}= \sqrt{13} =3.605551275464

Equation of the line:

y = 0.66666666666667x + 1.3333333333333

or

y=\frac{2}{3}x+\frac{4}{3}

When x=0, y = 1.3333333333333

When y=0, x = -2

the price of gravel is $24 for every 3/8 ton. Kate wants to know the price of 2 tons of gravel. at that rate, what is the price
andreev551 [17]

Answer:

<h2>$128</h2>

Step-by-step explanation:

This problem is on rate.

firstly we have to find the rate at which 1 ton is sold

given that 3/8 ton is sold for $24

hence 1 ton will be sold for X

cross multiply

X = 24/3/8

inverse the denominator and multiply the result with the numerator we have

X= 24*8/3

X= $64

Now having found out that 1 ton cost $64

2 tons will cost =64*2

                         = $128

Therefore at this rate two tons will cost $128

Which of the following is a polynomial with roots: − square root of 5 , square root of 5 , and 3? (6 points)
Karo-lina-s [1.5K]

Let's check the first polynomial , that is

P(x)= x^3 -3x^2 -5x+15

We need to factor it first and for that we have to do grouping and factoring .

P(x) = x^2(x-3)-5(x-3) \\ P(x) = (x^2 -5)(x-3)

TO find the roots, we need to set P(x) to 0, that is

(x^2 -5)(x-3)=0 \\ x^2 - 5= 0 , x-3 =0 \\ x^2 = 5 , x=3 \\ x = \pm \sqrt{5} , x=3

SO the correct option is A .

The sum of three consecutive odd integers is 183
Tatiana [17]
Since any off integer is in the form (2x+1) then three consecutive integers who's sum is 183 will be in the form (2x+1)+(2x+3)+(2x+5)=183
6x+9=183
subtracting 9
6x=174
dividing by 2
3x=87
dividing by 3
x=29
so the integers are
2(29)+1=59
2(29)+3=61
2(29)+5=63
to check our answer let us sum up the integers
59+61+63=59+1+60+63=60+60+63=183
