inn [45]

Answer:

Rotation

Step-by-step explanation:

Given:

Triangle DEF is congruent to Triangle GHJ by the SSS theorem

To find: transformation required to map Triangle DEF onto Triangle GHJ

Solution:

Two figures are said to be congruent if they overlap each other.

Two polygons are said to be congruent if they have same size and shape.

A rotation is a transformation that turns a figure about the center of rotation.

In ΔRST, r = 5 cm, t = 6.8 cm and ∠T=23°. Find all possible values of ∠R, to the nearest 10th of a degree.

8090 [49]

Answer:

$\angle r=16.696$

Step-by-step explanation:

From the question we are told that:

Dimension

r = 5 cm

t = 6.8 cm

∠T=23°

Generally the equation of sine rule i is mathematically given by

$\frac{sin \angle r}{R} =\frac{sin \angle t}{T}$

$\frac{ \angle r}{1} =sin^-^1(\frac{sin \angle t*R}{T})$

$\frac{ \angle r}{1} =sin^-^1(\frac{sin23*5}{6.8})$

$\angle r=16.696$

Monthly rent at Lake View Apartments has increased annually and is modeled by the exponential equation y = 2,400(1.04)x. What is

AfilCa [17]

Answer:

The percent increase per year is 4%

Step-by-step explanation:

we have

$y=2,400(1.04^x)$

This is a exponential function of the form

$y=a(b^x)$

where

y represent the monthly rent at Lake View Apartments

x represent the number of years

a is the initial value (y-intercept)

b is the base

r is the rate or percent increase

$b=(1+r)$

The percent increase per year is the base of the exponential function decreased by 1.

$r=b-1$

In this problem we have

$a=\$2,400$ ---> initial value

$b=1.04\\r=1.04-1=0.04=4\%$

Therefore

The percent increase per year is 4%
