Answer:
8.9 9
6.4 6
Step-by-step explanation:
Answer:
Using the formula a² + b² = c², we can plug in those two numbers, which I assume are the legs, to get our answer.
- Once we plug it in, we have to isolate the variable.
THEN
- We must square root (√) the final answer. Like so:
6.4² + 8.9² = c²
DO: The variable is already isolated, so we must do this a little differently. We'll square each number like it shows, and then add the two numbers together.
6.4² = 40.96
8.9² = 79.21
NOW: We can add them together.
40.96 + 79.21 = 120.17
LOOK: 120.17 = c²
We must now get rid of the 2, by square rooting both sides!
10.9622078068 = c

find the hypotenuse for the following
Answer:
6.403 units
or [tex]\sqrt{41}[/tex]
Step-by-step explanation:
We want the hypotenuse.
The hypotenuse is from the point (-3, -1) to point (2, 3)
D( (-3, -1), (2, 3)) = root ( (2 - (-3))^2 + (3 - -1)^2 ) =
D( (-3, -1), (2, 3)) = root ( 5^2 + 4^2) = root( 25 + 16)
D( (-3, -1), (2, 3)) = root ( 41)
D( (-3, -1), (2, 3)) = 6.403 units
Answer:

A group of friends will host a party and split the cost of food and supplies evenly. The cost that each person will pay is inversely proportional to the number of friends who decide to host. If five friends host the party, each person pays $12 for food and supplies. Write an equation that describes the relationship between cost (c) that each host pays and the number of hosts (h).
Answer:
C=60/h
Step-by-step explanation:
Cost is inversely Proportional to the number of friends who decides to host.
If five (5) friends host the party,
And each friend pays $12 for food and supplies
The equation that describes the relationship is
C=k ×1/h
Where,
C= cost that each host pays
K=constant
h=number of host
Therefore,
$12=k×1/5
$12=k/5
Make k the subject of the formula
$12=k*1/5
Multiply both sides by 5
12×5=k*1/5×5
60=k*5/5
60=k*1
60=k
Sub the value of k into
C=k ×1/h
C=60*1/h
C=60/h
Answer:
D) c = 60∕h

Can somebody help me find the Domain, Range, Horizontal Asymptote, Y-Intercept, and End Behavior of the function f(x) = -2e^x + 4 ?
Answer:
Domain = R
Range = (-∞, 4)
Hor. asymp = y=4
Y intercept: f(0) = (0,2)
end behaviour:
x → -∞: f(x) → 4
x→ ∞: f(x) → -∞
Step-by-step explanation:
For the domain, it is R because e^x works for all values of x
For the range, y will never be above 4.
The hor. asymptote is found via [tex]\lim_{x \to -\infty} f(x)[/tex] there the e term will be zero, so what is left is y=4.
Y intercept, fill in f(0)
end behaviour: for small x, y goes to the asymptote, for large x, y goes to minus infinity.
Final answer:
Explained the Domain, Range, Horizontal Asymptote, Y-Intercept, and End Behavior of f(x) = -2e^x + 4
Explanation:
Domain and Range:
Domain: All Real Numbers
Range: f(x) ≤ 4
Horizontal Asymptote:
Horizontal Asymptote: y = 4
Y-Intercept:
Y-Intercept: (0, 2)
End Behavior:
End Behavior: As x → ∞, f(x) → 4; As x → -∞, f(x) → -∞
Emily is training for a 10K race. On day one, she runs for 20 minutes. On day two, she runs for 30 minutes. On day three, she runs for 40 minutes. If this pattern continues, how many minutes will she run on day 8?
Answer:
90 minutes
Step-by-step explanation:
Given that On day one, she runs for 20 minutes. On day two, she runs for 30 minutes. On day three, she runs for 40 minutes, this pattern may be presented as an arithmetic sequence shown below
20, 30, 40 ...
For an arithmetic sequence whose first term is a, and a common difference d, the nth term of the sequence may be given as
Tn = a + (n - 1)d
Hence the first term is 20, the common difference d is 10
On the 8th day, the 8th term
T8 = 20 + (8 - 1) 10
= 20 + 70
= 90 minutes
Final answer:
Emily will run for 90 minutes on day 8, calculated by applying the formula for the n-th term of an arithmetic sequence with a first term of 20 minutes and a common difference of 10 minutes.
Explanation:
Emily is training for a 10K race with a pattern of increasing her running time by 10 minutes each day. On day one, she runs for 20 minutes, on day two for 30 minutes, and on day three for 40 minutes. To calculate how many minutes she will run on day 8, we can observe this as an arithmetic sequence where the common difference is 10 minutes.
Using the formula for the nth term of an arithmetic sequence, which is an = a1 + (n-1)d, where:
a1 is the first termd is the common differencen is the term numberWe know that a1 is 20 minutes, d is 10 minutes, and n is 8 because we are looking for the time on day 8.
Therefore, a8 = 20 + (8-1)
10 = 20 + 70 = 90 minutes.
So, on day 8, Emily will run for 90 minutes.

Answer:
[tex]\dfrac{5}{y+5}[/tex]
Step-by-step explanation:
Here, we have to find the sum of 2 fractions:
1st fraction: [tex]\dfrac{3y}{y^{2}+7y+10}[/tex]
2nd fraction: [tex]\dfrac{2}{y+2}[/tex]
Considering the denominator of 1st fraction:
[tex]y^{2}+7y+10[/tex]
Using factorization method:
[tex]7y[/tex] can be written as [tex](2y + 5y)[/tex].
[tex]\Rightarrow y^{2}+2y+5y+10[/tex]
Taking 5 common from [tex]5y+10[/tex] and y common from [tex]y^{2}+2y[/tex]: [tex]\Rightarrow y(y+2)+5(y+2)[/tex]
Now taking [tex](y+2)[/tex] common:
[tex]\Rightarrow (y+5)(y+2)[/tex]
[tex]\dfrac{3y}{y^{2}+7y+10}[/tex] can be written as [tex]\dfrac{3y}{(y+5)(y+2)}[/tex]
Now, calculating the sum:
[tex]\dfrac{2y}{(y+5)(y+2)} + \dfrac{2}{y+2}[/tex]
Taking LCM and solving:
[tex]\Rightarrow \dfrac{3y+2(y+5)}{(y+5)(y+2)}\\\Rightarrow \dfrac{5y+10}{(y+5)(y+2)}\\\Rightarrow \dfrac{5(y+2)}{(y+5)(y+2)}\\\Rightarrow \dfrac{5}{(y+5)}[/tex]
Hence, answer is [tex]\dfrac{5}{y+5}[/tex].

Step 1: add basic shape areas belonging to the composite shape Step 2: subtract basic shape areas NOT belonging to the composite shapeb. the surface area of a three-dimensional composite figure
As we know (3D) composite objects are made of two or more objects put together. To find the surface area of a 3D composite object, we need:
Step 1: find the outside surface area of each object Step 2: add the surface areas togetherHope it will find you well
Final answer:
To find the area of composite figures, break them down into simpler shapes and sum up their areas. For three-dimensional figures, find individual surface areas and add them up.
Explanation:
Area can be determined by counting the number of squares inside a shape on 1 cm x 1 cm graph paper. For composite figures, break them down into simpler shapes, find their individual areas using appropriate formulas, then add them up. For three-dimensional composite figures, calculate surface area by finding the sum of individual surface areas of each component shape.

Ed lined up 10 guitar picks across his desk. Each pick weighs 12 mg wide. How many grams does his entire set of guitar picks weigh?
Answer:
120 milligrams because 12 mg *10 =120
Ed's entire set of guitar picks, with each pick weighing 12 mg and having 10 picks in total is 0.12 grams.
To calculate the total weight of the guitar picks in grams, we first need to know that there are 10 guitar picks and each pick weighs 12 mg.
Knowing that there are 1000 milligrams in a gram, we can convert the weight of one pick into grams:
Weight of one pick in grams = 12 mg / 1000 = 0.012 grams.
Next, we multiply this by the total number of picks to get the combined weight:
Total weight of 10 picks = 0.012 grams pick * 10 picks = 0.12 grams.
So, Ed's entire set of guitar picks weighs 0.12 grams.
The daily gazzette has 25 companies that pay for advertising each month the newspaper wants to increase its advertisers by 5 each month what equation can be used to determine m the number of months it will take to double it
Answer: 25+5m =50
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The actual number of companies that pay for advertising each month (25) plus the product of the companies added per month (5) and the number of months (m) must be equal to the actual number of advertisers multiplied by 2 ( since they want to double it ).
Mathematically speaking:
25 +5m = 25 (2)
25+5m =50
Feel free to ask for more if needed or if you did not understand something.
Answer:
m=a/5
Step-by-step explanation:
From the statement, you have that the number of advertisers would be equal to the number of companies the daily gazzette has plus the 5 advertisers the newspaper wants to increase each month multiply for the number of months. From this, the expression would be:
2a=a+5m, where
a= number of advertisers
From this, we can isolate m:
5m=a
m=a/5
You can solve it to find the number of months it will take to double the advertisers:
m=25/5= 5
It will take 5 months as:
25+(5*5)= 25+25= 50
Graph y = 3/4 + 2.??? Idk what this is
Answer:
This equation is for a linear graph.
y = mx + b, where m is the slope and b is the y-intercept. To graph this, plot a point at (0, 2), as that is your y-intercept.
As for the slope, always remember [tex]\frac{rise}{run\\}[/tex]. What this means is you first count up before counting horizontally for the slope. Your slope is 3/4, so from your y-intercept, count three numbers up, and four to the right (since the slope is positive). This second point should be at (4, 5)

Brad had $530.45 in his checking account. He wrote checks for $16.50 and $95.68. He also made a deposit of $19.13. What is the approximate final balance in his account?
Answer:
Around $437.4
Step-by-step explanation:
Answer:
437.40
Step-by-step explanation:
a check would be a decrease to his checking account balance so 530.45 minus 16.50 would equal 513.95. 513.95 minus 95.68 equals 418.27. a deposit would be a increase to his balance. 418.27 plus 19.13 would equal 437.40.

To create equivalent fractions, you choose a simple fraction like 1/2. You then multiply both the numerator and denominator of this fraction by the same number to get a new fraction. You can do this 15 times to get 15 different equivalent fractions.
Explanation:The subject is finding equivalent fractions. Let's start with a simple fraction like 1/2. Equivalent fractions are just multiples of this fraction. So, we multiply both the numerator (top number) and the denominator (bottom number) by the same number to get an equivalent fraction. Here are some examples:
1/2 x 2/2 = 2/4 1/2 x 3/3 = 3/6 1/2 x 4/4 = 4/8 And so on...
Following this method, you can create 15 different equivalent fractions for 1/2. Remember that the fractions should be in their simplest form, meaning that there's no number (except for 1) that could divide both the numerator and denominator evenly.

The equation that relates the mass of the object m and the length of the spring s is s = 0.3m, based on the given information that a 30-gram object stretches the spring 9 centimeters.
The direct variation between the mass of an object and the length of a spring can be described by the equation:
s = k × m, where s is the spring length, m is the mass of the object, and k is the constant of proportionality.
For a 30-gram object stretching the spring to 9 centimeters, the constant k can be found using:
k = s/m, which is k = 9 cm / 30 g, so k = 0.3 cm/g.
Therefore, the equation that relates the mass of the object m and the length of the spring s is s = 0.3m.

Given
Shape: Rectangle
[tex]Height: k^2 + 3[/tex]
[tex]Width: k^2 + 7[/tex]
Required
Area of the rectangle
The area of a rectangle is calculated as thus;
[tex]Area = Length * Width[/tex]
By substituting [tex]k^2 + 3[/tex] for height and [tex]k^2 + 7[/tex] for width; This gives
[tex]Area = (k^2 + 3)(k^2 + 7)[/tex]
Expand the bracket
[tex]Area = k^2(k^2 + 7) + 3(k^2 + 7)[/tex]
Open each bracket
[tex]Area = k^2*k^2 + k^2*7 + 3*k^2 + 3*7[/tex]
[tex]Area = k^4 +7 k^2 + 3k^2 + 21[/tex]
[tex]Area = k^4 +10 k^2 + 21[/tex]
Hence, the area of the rectangle in polynomial form is [tex]k^4 +10 k^2 + 21[/tex]
