Answer:

12.92 cm²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = \frac{1}{2} bh ( b is the base and h the perpendicular height )

Here b = 7.6 and h = 3.4 , thus

A = \frac{1}{2} × 7.6 × 3.4 = 3.8 × 3.4 = 12.92 cm²

The circumference of the earth is 2.4x109 miles. if you traveled at an average of 8.5x10 miles per hour, how long would it take
pshichka [43]

Answer:

282 hr   <======= see below

Step-by-step explanation:

Distance / rate = time

2.4 x 10^9 mi / 85 m/hr   = 28235294 hr

 You must have left the power of 10 off of your speed

     probably should be   8.5 x 10^6  perhaps?   then answer is 282

<h3>If speed was 8.5 x 10^5   then answer becomes ~ 2820   </h3>

Consider the graphs of f(x) and g(x).
butalik [34]

Answer:

The value of k is -7

Step-by-step explanation:

We are given the graph of f(x) and g(x). If g(x)=f(x)+k

If we shift f(x) k unit vertical get g(x).

If k>0 then shift up

If k<0 then shift down.

f(x) and g(x) are both parabola curve.

First we find the vertex of f(x) and g(x)

Vertex of f(x) = (3,1)

Vertex of g(x) = (3,-6)

We can see change in y co-ordinate only.

f(x) shift 7 unit down to get g(x)

g(x)=f(x)-7

Therefore, The value of k is -7

Solve for x.<br> y = (5+x}m<br> Answer?
Tanzania [10]

Answer:

x=ym−4

Step-by-step explanation:

y=(4+x)m

Here we have one equation with three unknowns. This cannot be "solved". We can only express one variable in terms of the other two.

Let's isolate x.

Divide through by m

ym=4+x

x=ym−4

(I really hope this helps)
