MULTIPLE CHOICE A thermometer is

1 answer:

4 0

The absolute value equation which could be used to obtain the greatest and least possible temperature values when the temperature reading is 17°F is (17 ± 2)°F

Thermometer accuracy = ±2°F
Thermometer reading = 17°F

The least possible value of temperature can be calculated thus :

Thermometer reading - thermometer accuracy

17 - 2 = 15°F

The highest possible temperature can be calculated thus :

Themometer reading - thermometer accuracy

17 + 2 = 19°F

Hence, the absolute value equation which represents the scenario is (17 ± 2)°F

Hey i got riddles for people

mina [271]

Answer:

The first riddle is Age. Some people love their age, some people hate their age. Age can change appearances and thoughts because as you mature you view things differently. If you take care of yourself, you will become die older than most people. Some people are fooled by age, they think someone is older or younger than they really are. Some people don't know someone's age, so it is a mystery. Some people try and hide their age. Age never decreases.

The second riddle is a shadow. A shadow is only one color, but it can be any shape or size. Shadows are stuck at the bottom, but it easily moves. Shadows appear in the sun, but not when it is raining because of the clouds. Shadows do no harm, and they can't feel anything.

The attendance at the art museum at the New Year's opening was 250 people. The attendance has been increasing at a rate of 3% ea

erastovalidia [21]

Given:

Initially the number of people at art museum = 250

Rate of increase = 3% per month

To find:

The number of people at art museum in the end of a year.

Solution:

The general exponential growth model is:

$y=a\left(1+\dfrac{r}{100}\right)^t$

Where, a is the initial value, r is the rate of increase in % and t is the time period.

We know that, 1 year = 12 months.

Putting a=250, r=3 and t=12, we get

$y=250\left(1+\dfrac{3}{100}\right)^{12}$

$y=250\left(1+0.03\right)^{12}$

$y=250\left(1.03\right)^{12}$

$y=250(1.42576)$

$y=356.44$

$y\approx 356$

The number of people at the end of a year is 356. Therefore, the correct option is D.

M = y2 - y1 / x2 - x1 What is the slope of line JK? A) 5/9 B) 9/5 C) -5/9 D) -9/5

meriva

So
(x,y)

J is -4 to the right and 2 up so
(-4,2)

K is 5 to the right and -3 up
(5,-3)

(x,y)

x1=-4
y1=2
x2=5
y2=-3

M= $\frac{y2-y1}{x2-x1}$
M= $\frac{-3-2}{5-(-4)$
M= $\frac{-5}{5+4}$
M= $\frac{-5}{9}$

answer is C -5/9
