Answer:
The change for the day is 29 3/4Step-by-step explanation:
In this problem, we are expected to calculate the change in the price of a particular stock
Given that the days high is 80 1/4
and also that the days low is 50 1/2
we can calculate the change by subtracting the days low from the days high
i.e 80 1/4- 50 1/2= 321/4-101/2= (321-202)/4= 119/4 = 29 3/4
hence the change for the day is 29 3/4
Also we can calculate the percentage change as
%change = (high-low)/low*100
%change= 80 1/4- 50 1/2/50 1/2= 29 3/4/50 1/2 *100
%change= 119/4*2/101 *100= 119/202*100= 0.589*100= 58.9%
%change= 58.9%

Answer:
≤
Step-by-step explanation:
First we solve 5(x + 2) ≥ 2(x + 8).
5x + 10 ≥ 2x + 16
3x ≥ 6
x ≥ 2.
Now we place an equal sign into the box:
4(x - 6) = 2(x - 10)
4x - 24 = 2x - 20
2x = 4
x = 2.
For the solution to only have 1 value, the solution must be x = 2.
Therefore we must have x ≥ 2 and x ≤ 2.

2. Continuous data are usually _____________________, but discrete data are usually ______________________.
Answer:
Measured and Counted.
Step-by-step explanation:
Continuous data are usually “Measured”, but discrete data are usually “Counted”.
The continuous data are the data that can be measured, for example, Height of children, time in the race, length of leaf, etc. In this case, the data is taken within the range. While the discrete data is the data that can be counted. For example, the number of employees in the office, the number of students in the school, the result of rolling dice, etc. In this case, the data is a fixed number. Accordingly, the continuous data is measurable and discrete data is countable.

Answer:
5.3× 10⁴= ?
Step-by-step explanation:
10⁴ can also be written as 10×10×10×10= 10000
so, 5.3 × 10000= 53000
Scientific notations are the way through which a very small or a very large number can be written in shorthand. The value of 5.3×10⁴ in standard form is equal to 53,000.
What are Scientific notations?Scientific notations is the way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.
For example, 6,500,000,000,000 can be written as 6.5e+12.
Given the numerical value 5.3×10⁴ which is needed to be written in the standard form, therefore, we can write,
5.3 × 10⁴
= 5.3 × 10,000
= 53,000
Hence, the value of 5.3×10⁴ in standard form is equal to 53,000.

The change in kinetic energy (in joules) as a horse accelerates from canter to gallop is found using the expression 1/2 times 350 times (12 2 Minus 6 2
Answer:
[tex]\mathtt{\Delta K.E = 10500 \ J}[/tex]
Step-by-step explanation:
Given that:
the expression for the change in kinetic energy = [tex]\dfrac{1}{2} \times 350 \times ( 122 -62)[/tex]
Recall that
Kinetic energy K.E = [tex]\dfrac{1}{2}mv^2[/tex]
where,
m = mass of the horse
v = velocity of the horse
The change in kinetic energy between two instant times can be expressed by the relation
[tex]\Delta K.E = K.E_2 - K.E_1[/tex]
[tex]\Delta K.E =\dfrac{1}{2}mv^2_2- \dfrac{1}{2}mv^2_1[/tex]
[tex]\Delta K.E =\dfrac{1}{2}m(v^2_2-v^2_1)[/tex]
where;
m = 350
[tex]v_2[/tex] = 122
[tex]v_1[/tex]= 62
[tex]\Delta K.E =\dfrac{1}{2} \times 350 \times (122-62)[/tex]
[tex]\Delta K.E =\dfrac{1}{2} \times 350 \times (60)[/tex]
[tex]\Delta K.E = 350 \times 30[/tex]

The population of Austin, Texas, was about 494,000 at the beginning of a decade. The population increased by 3% each year. Write an exponential growth model that represents the population y (in thousands) t years after the beginning of the decade. Find and interpret the y-value when t = 10.
Answer:
y(t) = 494 (1.03)^t
y(10) = 663,89
Step-by-step explanation:
An increase in population by 3% each year means that at the end of each year, the population is 1.03 times what it was at the start of the year
This increase in population continues for t years
Exponential growth model that represents the population y (in thousands) t years after the beginning of the decade is
y(t) = 494 (1.03)^t
Where,
y = population
t = number of years
Find y when t = 10
y(t) = 494 (1.03)^t
y(10) = 494 (1.03)^10
= 494 ( 1.3439)
= 663.8866
Approximately y(10) = 663.89
This means that after 10 years from when the population was 494,000, it increased to 663,89.

You have obviously determined the correct entry in the top box of each pair. What you seem to have failed to observe is that the bottom box in each pair needs exactly the same entry as the top box.
_____
You figure this out by looking at the stuff that is outside the box. The numbers and symbols for the second box show how the function indicated outside the first box is evaluated. That is f(x) at the top becomes 4x at the bottom, where x (in this case) is x/4 for both.
Find the distance between the points (-16,10) and (2,-14)
Answer: The distance is 30
Step-by-step explanation:
To find the distance between the two points,find the difference between the x and y values, square them and add them to find their square root.
10 - (-14) = 24
-16 - 2= -18
24^2 + 18^2 = d^2 where d is the distance
576 + 324 = d^2
900 =d^2
d = [tex]\sqrt{900}[/tex]
d= 30
Answer:
d=30
Step-by-step explanation:
distance between 2 points: d
d=√(x2-x1)²+(y2-y1)² (-16,10) and (2,-14)
d=√(2-(-16)²+(-14-10)²
d=√18²+(-24)²
d=√324+576
d=√900
d=30
You have quarters and dimes that total $2.80. Your friend says it is possible that the number of quarters is 8 more than the number of dimes. Is your friend correct? Let d represent the number of dimes
An equation that models this situation is _____=2.80
(I’m so stupid help)
Answer:
Step-by-step explanation:
d = number of dimes
2.80 = 0.1d + 0.25 (d + 8 )
2.80 = 0.1d + 0.25d + 2 Combine like terms
2.80 = 0.35d + 2 Subtract 2 from both sides
0.80 = 0.35d Divide both sides by 0.35
d ≈ 2.29
No, it's not possible to have more quarters than dimes when the total is $2.80 because it's not possible to have part of a dime.
How do you find the domain and range of a function and write it in set notation? What is the process of finding it? Tips and tricks are very much appreciated. I literally have no clue how to get them. Send help?
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis
Step-by-step explanation:
plz forgive me if my answer is wrong
Domain = looking for the very far left value and the very far right value on the x-axis, and only x-axis, so the farthest left x-axis value and the farthest right x-axis value.
Range = very bottom y-value, and very top y-value
In both cases, if the arrows extend forever then that means you could have the value of infinity.

Answer:
x = 7.5
Step-by-step explanation:
Step 1: Subtract x from both sides.
1.5x−0.5−x=x+3.25−x
0.5x−0.5=3.25
Step 2: Add 0.5 to both sides.
0.5x−0.5+0.5=3.25+0.5
0.5x=3.75
Step 3: Divide both sides by 0.5
0.5x ÷ 0.5 = 3.75 ÷ 0.5
