How do you find the area of each triangle?
Pachacha [2.7K]
There's a big triangle with base (2+6) meters and altitude 5 meters.

The formula for the area of a triangle of base B and altitude H is

A = BH/2.

The area of the large triangle is thus A = (8 meters)(5 meters)/2, or 
20 square meters.

Use A = BH/2 to find the areas of the other triangles.

Use simple interest to find the interest and ending balance
hammer [34]

Answer:

Interest = $240

Ending Balance = $990

Step-by-step explanation:

Applying I = prt/100

= (750*4*8)/100

= 240

Therefore Interest = $240

Adding Interest to Principal

= $240 + $750 = $990

Which of the following can be the parent function of the graph? Select two of the following that apply.
maks197457 [2]

Answer:

Options c and d

Step-by-step explanation:

Given is a graph with period pi.

ii) The graph is discontinuous

iii) x intercepts are say (a) units to the right of y axis and repeats for every interval of pi.

Fix the function

a) y = sinx cannot be this graph because sinx is a continuous graph

b) y =cosx cannot be this graph because cosx is a continuous graph

e) y = sec x is undefined for the range (-1,1) since the given graph is defined in this interval, secx is not answer.

f)y = csc x is undefined for the range (-1,1) since the given graph is defined in this interval, cscx is not answer.

c) y=tanx is a discontinuous graph at x = odd multiples of pi/2

Hence the given graph can be of the form y =- tan (2x+a) which shows reflection over y axis,

d) y = cotx can also be this graph with adjustments for period and horizontal shift.

So answers are c and d
