a truck traveled 60 km per hour the first hour, 45 miles per hour as the next 30 minutes and 50 km per hour in next 45 minutes w

-BARSIC- [3]

Answer:
134 kilometers or 83 miles.

Explanation:
First make all the units equivalent, so
60 km/h = 60 km/h or 37.28 m/h
45 m/h = 72.42 km/h or 45 m/h
50 km/h = 50 km/h or 31.07
So in one hour the car has gone 60 km or 37.28 m because they travel at 60km/h, which means they get that far in that amount of time.
In half an hour they get half of 45 miles, because 45 m/h means they get 45 miles in 60 minutes, so in 30 minutes, or half and hour, they are getting half of 45 = 22.5 miles or 36.21 kilometers.
In 45 minutes they are getting 75% of 50 km because 45 minutes is 75% of an hour. So 75% of 50 is 37.5 km or 23.3 miles.

Add this all together and get:
Kilometers:
60 + 36.21 + 37.5 = 133.71 km
Miles:
37.28 + 22.5 + 23.3 = 83.08 m
133.71 km = 83.08 So it checks out.
This is approximately 134 km or 83 miles.

Find the vertex and y intercept of the quadratic function

riadik2000 [5.3K]

Answer: 5) Vertex = (2, 28) y-intercept = 40 → (0, 40)

6) Vertex = (2, 11) y-intercept = 7 → (0, 7)

<u>Step-by-step explanation:</u>

The y-intercept of the equation is when x = 0. It is the c-value when given in standard form: y = ax² + bx + c

To find the vertex, use the Axis of Symmetry equation to find the x-value

x = -b/(2a). Then plug the x-value into the equation to find the y-value.

5) y = 3x² - 12x + 40

↓ ↓ ↓

a=3 b= -12 c=40

$\text{AOS:}\quad x=\dfrac{-b}{2a}\quad =\dfrac{-(-12)}{2(3)}\quad =\dfrac{12}{6}\quad =2$

Min: y = 3(2)² - 12(2) + 40

= 3(4) - 24 + 40

= 12 - 24 + 40

= 28

Vertex: (2, 28) y-intercept = 40

*******************************************************************************************

6) y = -x² + 4x + 7

↓ ↓ ↓

a= -1 b=4 c=7

$\text{AOS:}\quad x=\dfrac{-b}{2a}\quad =\dfrac{-(4)}{2(-1)}\quad =\dfrac{-4}{-2}\quad =2$

Max: y = -(2)² + 4(2) + 7

= -(4) + 8 + 7

= -4 + 8 + 7

= 11

Vertex: (2, 11) y-intercept = 7

If 2/3(x-6)-3/4x=3 , then x= ?

Elan Coil [88]

Answer:

The value of x for the given expression is - 84

Step-by-step explanation:

Given expression as :

$\frac{2}{3}$ (x - 6) - $\frac{3}{4}$ x = 3

Taking LCM of 3 & 4

So, $\frac{8\times (x-6) - 9x}{12}$ = 3

or, 8 x - 48 - 9 x = 12 × 3

Or, 8 x - 9 x = 36 + 48

or, - x = 84

∴ x = - 84

Hence The value of x for the given expression is - 84 Answer
