coordinates:

T = (10, 5)

R = (5, 15)

S = (15, 15)

=========

If rotated 90 degree anticlockwise, (x,y) becomes (-y,x)

T' = (-5, 10)

R' = (-15, 5)

S' = (-15, 15)

point these coordinates and this will be the answer.

the triangle is graphed below as blue

the function f(t)= 3,500(1.003)^t gives the value of a saving account t months after it was opened.How long will it take for the

Pavel [41]

Answer:

After 19 months,value in the account will reach $3700

Step-by-step explanation:

The value of a savings account f(t) in terms of t ( number of months since account opening) is given as $3,500(1.003)^{t}$

We need to determine the value of t when f(t)>=3700

Expressing it in equation form,

$3,500(1.003)^{t} >= 3700$

$=>(1.003)^{t} >= \frac{3700}{3500}$

$=>(1.003)^{t} >= 1.057$

Taking log of both sides,

$=>t * log(1.003) >= log(1.057)$

$=>t >= \frac{log(1.057)}{log(1.003)}$

$=>t >= 18.51$

So t = 19.

Investment A 50 increases each year by 8% investment B 60 increases by 3 each year what year will investment A be bigger than be

UkoKoshka [18]

Answer:

After 10 years the investment A will be bigger than investment B.

Step-by-step explanation:

In Investment A, 50 increases each year by 8% and in investment B, 60 increases by 3 each year.

If after x years the investment A will be equal to investment B, then we can write the equation as

$50(1 + \frac{8 \times x}{100}) = 60 + 3x$

⇒ 50 + 4x = 60 + 3x

⇒ x = 10

Therefore, after 10 years the investment A will be bigger than investment B. (Answer)

Question 20

zimovet [89]

9514 1404 393

Answer:

(d) A = 18 units²

Step-by-step explanation:

Line CE can be considered to be the base of two triangles. It is 6 units long. The upper triangle is 4 units high, and the lower triangle is 2 units high. The formula for the area of a triangle is ...

A = 1/2bh

Then the sum of the areas of the two triangles is ...

A = 1/2(6)(4) +1/2(6)(2) = 12 +6 = 18

The area of the polygon is 18 square units.
