Answers

Answer 1

Answer:

[tex]Domain:= \{-5,4,-8\}[/tex]

[tex]Range:=\{0,3\}[/tex]

Step-by-step explanation:

Given

[tex]H = \{(-5,0),(4,3),(-8,3)\}[/tex]

Required

The domain and the range

A function represented as:

[tex]Function = \{(x_1,y_1),(x_2,y_2)......(x_n,y_n)\}[/tex]

Where:

[tex]Domain=x_1,x_2,....,x_n[/tex]

[tex]Range=y_1,y_2,....,y_n[/tex]

So:

[tex]H = \{(-5,0),(4,3),(-8,3)\}[/tex]

[tex]Domain:= \{-5,4,-8\}[/tex]

[tex]Range:=\{0,3\}[/tex]

What is the simple interest rate on a $2300 investment paying $906.20 interest in 19.7 years?

Answers

Answer:

2%

Step-by-step explanation:

Given data

Principal=$2300

Simple interest=$906.20

Time= 19.7years

Required

The rate in percentage

We know that

SI=PRT/100

substitute

906.20=2300*R*19.7/100

906.20=45310R/100

cross multiply

906.20*100= 45310R

90620= 45310R

R= 90620/45310

R=2%

Hence the rate is 2%

  (5, 1) or maybe (h, k)

Step-by-step explanation:

The given form has no letters other than the variable. The vertex in this vertex-form equation can be read from the expression as (5, 1).

In the generic vertex form ...

  f(x) = a(x -h)² +k

the letters (h, k) are used to represent the vertex.

Answer:

a)29

b)70

Step-by-step explanation:

The sum of the interior angles in a triangle is 180.

a)95+56+a=180        b)40+2b=180

151+a=180                     2b=180-40

a=180-151                      2b=140  /2

a=29                              b=70

Every angle in a circle must add to give 180 so therefore for the first question =
a) 95+56+__ = 180 so the answer would be 29
Isosceles triangles have two identical angles inside that need to be the same.
b) 180-40=140 and to have two identical angles half 140 which gives you a final answer of 70

I have an old alarm clock, on which the hands move at only 95% of the speed that they should do.

I need it to wake me up at 7.30 am, so every night, at 10.30pm, I change the time shown on the

clock so that it will show the correct time at 7.30 am when the alarm goes off.

(a) What time does the clock show at 10.30 pm, immediately before I change it?


(b) What time do I change it to?


Please help immediately!!!

Answers

Answer:

  a) 9:45 pm

  b) 10:57 pm

Step-by-step explanation:

In the 15 hours between 7:30 am and 10:30 pm, the clock hands will have moved 15×0.95 = 14.25 hours = 14 hours and 15 minutes.

At 10:30 pm, the clock indicates 9:45 pm.

__

b) In the 9 hours between 10:30 pm and 7:30 am, the clock will have moved 9×0.95 = 8.55 hours, or 8 hours 33 minutes. That is, the clock needs to be set 27 minutes ahead of the actual time.

The clock need to be set to 10:57 pm.

_____

Alternate solution

At 95% speed, the clock loses 5%×60 minutes = 3 minutes each hour. In the 15 hours from morning to night, the clock will be 45 minutes slow. It will indicate 9:45 at 10:30 pm.

In the 9 hours from night to morning, the clock will lose 27 minutes so needs to be set 27 minutes fast. It should be set to 10:57 pm at 10:30 pm.
