Answer:

so say you have 76%+52% you would just type 76% in to you'r calculator and you would get .76 and if you do the same for 52% you would get .52 so it would be .76+.52. Hope this makes sense :)

a car left town A at 10:00 am and travelled towards town B at the average speed of 70 km/h. At the same time a truck left town B
Softa [21]
The important formula to this problem is distance=rate(time) or d=rt

Now, the speed of the car is 70 km/h, and the speed of the truck is 50 km/h. It will take the two vehicles the same amount of time to meet since they both left at the same time. So, since distance equals rate times time, and t = time:

the distance of the car = 70t
the distance of the truck = 50t

Because they both left in opposite directions, and the towns are 420 kilometers apart, the equation for this would be

70t+50t=420

We now solve the equation.

70t+50t=420 \\ 120t=420 \\  \frac{120t}{120}= \frac{420}{120}  \\ t=3 \frac{1}{2}

It will take the vehicles 3 and a half hours to meet. Since we're looking for the time, 3 and a half hours from 10:00 AM is 1:30 PM.

So, the car and the truck will pass each other at 1:30 PM.

If f(x) = -3x + 4, find f(3x + 3)
Alex17521 [72]

Remark

What this is telling you to do is put 3x + 3 in the question wherever there was an x to start with.

Solution

f(x) = -3x + 4

f(3x + 3) = - 3(3x + 3) + 4

f(3x + 3) = -3*3x + (-3)*(3) + 4

f(3x + 3) = - 9x - 9 + 4

f(3x + 3) = -9x - 5 <<<<< Answer

function h is a transformation of the parents tangent function such that h(x)=-tan(1/2x). Which graph represents function h?
Nuetrik [128]

The graph that represents function h is the graph in; Option C

<h3>How to Interpret Graph Transformations?</h3>

The parent function is; f(x) = tan (x)

The transformed function is; h(x) = -tan(¹/₂x)

Now, from general tangent function we know that; y = tan(Bx)

Thus, period = π/(¹/₂)

From the given transformation that produced the h(x) function and when we look at the given graphs, the one that represents the function h is Option C.
