Find the distance between (-3, -4) and (2, -4)
Answer:
[tex]\boxed{\sf{5}}[/tex]Step-by-step explanation:
Distance can be calculated using a distance formula.
⇒ (-3,-4) and (2,-4)Distance formula:
[tex]\Longrightarrow: \sf{\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} }[/tex]
The distance between (-3,-4) and (2,-4) are:
[tex]\Longrightarrow: \sf{\sqrt{\left(2-\left(-3\right)\right)^2+\left(-4-\left(-4\right)\right)^2}}[/tex]
Then, you solve.
[tex]\Longrightarrow:\sqrt{\left(2-\left(-3\right)\right)^2+\left(-4-\left(-4\right)\right)^2}=\boxed{\sf{5}}[/tex]
Therefore, the distance between (-3,-4) and (2,-4) is 5, which is our answer.I hope this helps you! Let me know if my answer is wrong or not.

let's follow BODMAS for solving this expression ~
the BODMAS rule states the order for solving a given question and the order lies in its full form which is as follows ~
B - brackets
O - of
D - division
M - multiplication
A - addition
S - subtraction
using the order , let's move to the expression given now ~
[tex]\dashrightarrow \: 8 \div 4(3 - 1) \\ \\ as \: the \: rule \: states \: , \: we \: will \: solve \: the \: brackets \: first \\ \\\dashrightarrow 8 \div 4(2) \\ \\ brackets \: again \\ \\ \dashrightarrow \: 8 \div 8 \\ \\ and \: finally \: divison \\ \\ \dashrightarrow \: 1[/tex]
hope helpful :D
The value of expression 8 divided by 4 (3-1) would be equal to 1
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the expression of 8 divided by 4 (3-1)
A negative divided by a negative is positive, therefore,
8 / 4 (3-1)
8 / 4(2)
8/8 = 1
Therefore, The value of 8 divided by 4 (3-1) is; 1

Is the following shape a rectangle? How do you know?
Answer:
B.Yes,the adjacent sides are perpendicular,and the opposite sides are parallel
Answer:
B. Yes, the opposite sides are perpedicular, and the opposite sides are parallel
Step-by-step explanation:
This is because for a rectangle to be a rectangle, it has to have four sides whose opposite sides are equal (so parallel) and adjacent sides meets at 90° (so perpendicular), both of which this shape is shown to be.

The circumference of a circle is 14 cm. Find the radius of this circle
Answer:
r ≈ 2.23 cm
Step-by-step explanation:
the circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
given C = 14 , then
2πr = 14 ( divide both sides by 2 )
πr = 7 ( divide both sides by π )
r = [tex]\frac{7}{\pi }[/tex] ≈ 2.23 cm ( to 2 dec. places )
On January 1, Trisha put $100 into a savings account that earns interest. That same day, Mark put some money into another savings account that also earns interest. After 5 years, Trisha’s account balance is 145% of her original balance, and Mark’s is 160% of his original balance. Mark and Trisha withdraw all of their money and use it to spend $225 at the amusement park. If together they have $40 left from their withdrawals after the amusement park, how much did Mark put into his savings account?
Trisha thinks that if Mark also put $100 into his account, then they would had more than $100 left after the amusement park. Is she correct or not? Explain.
Answer:
Mark deposited $75Trisha is not correctStep-by-step explanation:
The total of their account balances is equal to the total spent plus the remaining amount. The given relations tell us ...
Trisha withdrew $100 × 145% = $145Mark withdrew d × 160% = 1.6d . . . for some initial deposit d$145 + 1.6d = $225 +40 . . . . . withdrawals = spent + change__
a.Solving this equation, we can find Mark's withdrawal and his initial deposit.
145 +1.6d = 265
1.6d = 120 . . . . . . . the amount Mark withdrew
d = 120/1.6 = 75 . . . . the amount Mark deposited
Mark put $75 into his savings account.
__
b.Had Mark put $100 into his savings account, the total of withdrawals would have been ...
Trisha + Mark = $100 × 145% +$100 ×160% = $145 +160 = $305
After spending $225 of this amount, they would have had a leftover amount of ...
$305 -225 = $80
Trisha is not correct in her thinking that there would be more than $100 left over.
The reporter wants to test the store's claim against the alternative hypothesis that the wait time is actually greater than 60 minutes. what is the critical value for z for a hypothesis test using a 5% significance level? z* =
The critical value for z for a hypothesis test using a 5% significance level is 1.65
It is given that the reporter wants to test the store's claim against the alternative hypothesis that the wait time is actually greater than 60 minutes.
It is required to find the critical value for z for a hypothesis test using a 5% significance level.
What is a normal distribution?It is defined as the continuous distribution probability curve which is most likely symmetric around the mean. At Z=0, the probability is 50-50% on the Z curve. It is also called a bell-shaped curve.
We have a hypothesis H1 that wait time is actually greater than 60 minutes.
H1(T>60)
This is the case of the right-tailed hypothesis.
We have a significance level = 5% ⇒ 0.05
The statistics follow a normal distribution curve
Critical value = 1.6449 ≈ 1.65 (from the table at 5% significance level)
Thus, the critical value for z for a hypothesis test using a 5% significance level is 1.65

Timothy has a model of an armoured vehicle created using a scale of 1 : 72. If the length of the model is 3.3 inches, what is the actual length of the ed. e Limit vehicle, in feet?
Answer:
Length of armoured vehicle: 19.8 ft
Step-by-step explanation:
1 is to 3.3 in as 72 is to x:
1 72
-------- = --------
3.3 x
This yields x = 237.6 (inches), which corresponds to 237.6/12 (feet):

Leo buys pasta for 12 people,
(a)
Each person eats 100 grams of pasta.
One packet has 500 grams of pasta.
How many packets must Leo buy?
Answer:
3
Step-by-step explanation:
If each packet has 500 grams, and each person eats 100 grams, then one packet will feed five people (500/100=5). Since he will be buying pasta for 12 people, he will need to buy three packets, because 3*500=1500 grams. While there is some extra, buying only two packets would result in not enough pasta.

What is the fourth term of the geometric sequence whose first term is 7 and has a common ratio of -2
Answer:
-56
Step-by-step explanation:
It is often easiest to find terms of a sequence by simply writing each one based on the previous one. Here, the common ratio of -2 tells you that each term is -2 times the previous term.
The first four terms are ...
7, -14, 28, -56
The fourth term is -56.

triangle ABC is similar to triangle DEF. The ratio of the lengths of the corresponding sides of triangle ABC to triangle DEF is 2:3 what is the measure of DF
The ratio of the lengths of the corresponding sides of triangle ABC to triangle DEF is 2:3, and since side AC is the corresponding side of side DF -> Side DF = 3/2 side AC
-> Side DF = 2.5 x 3/2 = 3.75 cm.

Think carefully about the angle relationship the following represents.
What is the value of ∠JML?
Answer:
<JML=126 degrees, x=42
Step-by-step explanation:
well, something important to note here is that a straight line is allways equal to 180, and you have part of the 180 sitting there on the line being 54 degrees, so all you have to do is do 180-54=126 and that is the measure of <JML, to find x, you just reverse the steps you see, right now 3x=3*x so you want to reverse that and divide 126/3=42.
Angles are supplementary hence their sum is 180°
3x+54=1803x=180-54=126x=126/3x=42So
<JML=3x=126°

Given:
f(x)=x^2
g(x)=x-1
Find f(g(2))+g(f(-1))
Answer:
-1
Step-by-step explanation:
First, we need to work out the left-hand side.
find g(2) → g(2) = 2 - 1 which is 1next, find f(1) → f(1) = 1³ which is 1Now, we can work out the right hand side.
find f(-1) → f(-1) = -1³ which is -1then, find g(-1) → g(-1) = -1 - 1 = -2Finally we can work out the full sum: 1 + -2 = -1.
Hope this helps!
