Answer:

They will meet in 1.8 hours.

Step-by-step explanation:

Given that, distance between trains = 306 miles

Let they take time 't' to meet each other.

Speed of first train = 90 mph

Speed of second train = 80 mph

Let distance traveled by first train = D_1 miles

Formula for distance:

Distance = Speed \times Time

Distance traveled by first train, D_1 = 90t

Let distance traveled by first train = D_2 miles

Formula for distance:

Distance = Speed \times Time

Distance traveled by first train, D_2 = 80t

Total distance traveled is 306 miles.

i.e.

D_1+D_2=306\\\Rightarrow 90t +80t=306\\\Rightarrow 170t=306\\\Rightarrow t =\dfrac{306}{170}\\\Rightarrow \bold{t=1.8\ hr}

They will meet in 1.8 hours.

The image of the point
Stella [2.4K]

Answer:

(2, 0)

Step-by-step explanation:

First, find how the other point was transformed:

The x coordinate increased by 1, and the y coordinate increased by 4.

Now, do these same transformations to the other point, (1, -4)

x coordinate: 1 + 1 = 2

y coordinate: -4 + 4 = 0

So, the new point is (2, 0)

The area for a trapezoid is given by the formula below, where a and b are the lengths of the two bases and h is the height of th
aivan3 [116]

Answer:

C

Step-by-step explanation:

Given

A = \frac{h(a + b)}{2}

Substitute the given values with h = a, then

16.5 = \frac{a(a+8)}{2} ( multiply both sides by 2 )

33 = a(a + 8) ← distribute

33 = a² + 8a ( subtract 33 from both sides )

0 = a² + 8a - 33 ← in standard form

0 = (a + 11)(a - 3) ← in factored form

Equate each factor to zero and solve for a

a + 11 = 0 ⇒ a = - 11

a - 3 = 0 ⇒ a = 3

However, a > 0 thus a = 3

Hence the height is 3 feet

Find the function value, f(4) if f(x) = 12x - 1
Scrat [10]

Answer:

f(4) = 47

f(x) = 12x - 1

Let x = 4

f(4) = 12(4) -1

     = 48 -1

    = 47
