Answer:
[tex] A(\triangle ABC) = 7.2\: units^2 [/tex]
Step-by-step explanation:
C = (0, 7)
Since, point A lies in y-axis, so it's x coordinate will be zero. Line y = 2x + 1 passes through point A.
Therefore, plug x = 0 in y = 2x +1, we find:
y = 2*0 + 1 = 0 + 1 = 1
Hence, coordinates of point A are (0, 1).
Now, by distance formula:
[tex] AC= \sqrt{(0-0)^2 +(7-1)^2} [/tex]
[tex] AC= \sqrt{(0)^2 +(6)^2 }[/tex]
[tex] AC= \sqrt{0 +36 }[/tex]
[tex] AC= \sqrt{36 }[/tex]
[tex] AC= 6\: units[/tex]
Length of perpendicular CB dropped from point C (0, 7) to line y = 2x + 1 or 2x - y + 1 = 0 can be obtained as given below:
[tex] CB =\frac{|2\times 0+(-1)\times 7+1|}{\sqrt {2^2 +(-1)^2} } [/tex]
[tex] CB =\frac{|0-7+1|}{\sqrt {4 +1} } [/tex]
[tex] CB =\frac{|-6|}{\sqrt {5} } [/tex]
[tex] CB =\frac{6}{2.24} [/tex]
[tex] CB =2.68\: units [/tex]
By Pythagoras Theorem:
[tex] AB=\sqrt{AC^2 - CB^2} [/tex]
[tex] AB=\sqrt{6^2 - (2.68)^2} [/tex]
[tex] AB=\sqrt{36 - 7.18} [/tex]
[tex] AB=\sqrt{28.82} [/tex]
[tex] AB=5.36842621\: units [/tex]
[tex] AB\approx 5.37\: units [/tex]
[tex] A(\triangle ABC) = \frac{1}{2} \times AB\times CB[/tex]
[tex] A(\triangle ABC) = \frac{1}{2} \times 5.37\times 2.68[/tex]
[tex] A(\triangle ABC) = \frac{1}{2} \times 14.3916[/tex]
[tex] A(\triangle ABC) = 7.1958[/tex]
[tex] A(\triangle ABC) = 7.2\: units^2 [/tex]
What is the average price of an item sold considering quantity? 12 notepads at $4.20 25 folders at $0.80 3 calculators at $19.00
Answer:
Average price = $3.185
Step-by-step explanation:
Given:
12 notepads = $4.20 each
25 folders = $0.80 each
3 calculators = $19.00 each
Find:
Average price
Computation:
Average price = Total cost / Total number of item
Average price = [(12)(4.20) + (25)(0.80) + (3)(19)] / [12 + 25 + 3]
Average price = [(50.4) + (20) + (57)] / [40]
Average price = [127.4] / [40]
Average price = $3.185

Round 72.178 to the nearest hundredth.
Answer:
72.18
Step-by-step explanation:
The hundreth place is the second to the right of the decimal. So the number in the hundreths place is 72.178. When rounding, you look at the number behind the number you are rounding to. In this case, you want to look at the 8. If the number is 5 or above, you round up. 8 is above 5 so you round the 7 to an 8.
Answer: 72.18
Step-by-step explanation:
hope this helps
5n + 2n + 6 = 4n - 21
5n+2n+6=4n-21 group like terms on left side
7n+6=4n-21subtract 6 from both sides
7n=4n-27 subtract 4n from both sides
3n=27 divide both sides by 3
n=9

simplify cot^2 theta + 1.
a. csc^2 theta
b. 0
c. cot^2 theta
d. cos^2 theta
Answer:
A
Step-by-step explanation:
Using the Pythagorean identity
sin²x + cos²x = 1
Divide all terms by sin²x
[tex]\frac{sin^2x}{sin^2x}[/tex] + [tex]\frac{cos^2x}{sin^2x}[/tex] = [tex]\frac{1}{sin^2x}[/tex] , that is
1 + cot²x = csc²x
Thus
cot²θ + 1 = csc²θ → A
What is the volume of the hemisphere? 583.2cm^3cm 3 291.6cm^3cm 3 6882.3cm^3cm 3 3441.1cm^3cm 3 Item at position 3
Answer:
See Explanation
Step-by-step explanation:
The question has missing details; as the radius or an attachment of the hemisphere is not given.
However, I'll solve on a general terms.
The volume of a hemisphere is: [tex]V = \frac{2}{3}\pi r^3[/tex]
Take for instance
[tex]r = 14.9cm[/tex]
The volume becomes:
[tex]V = \frac{2}{3} * 3.142 * 14.9^3[/tex]
[tex]V = \frac{2 * 3.142 * 14.9^3}{3}[/tex]
[tex]V = \frac{20787.151516}{3}[/tex]
[tex]V = 6929.051cm^3[/tex]
So, all you need to do is plug in the value of radius in the formula.

Answer:
C- 4f less than or equal to 36
Step-by-step explanation:
The fish are 4 dollars each so how many fish you buy, you will multiply 4. Example- I will buy 5 fish so 5×4=20.
You can only spend less than 36 or you can spend exactly 36 dollars.
In my example I spent less than 36 dollars. I don't know if you understand but tell me if you need help.
A box is filled with 9 brown cards, 2 yellow cards, and 3 blue cards. A card is chosen at random from the box. What is the probability that it is a brown or a blue
card?
Answer:
9 / 14 for a brown , 3 / 14 for a blue
Step-by-step explanation:
1) summarize all cards 9 (brown) + 2 (yellow) + 3 (blue)= 14 cards.
2) probability depends on how many cards of a particular color, how more cards, then more probability.
3) 9 brown cards, so probability = 9 brown cards to divide all cards 14.

Under her cell phone plan, Aubrey pays a flat cost of $57.50 per month and $4 per gigabyte. She wants to keep her bill at $75.10 per month. Write and solve an equation which can be used to determine x, the number of gigabytes of data Aubrey can use while staying within her budget
Answer:
To stay within budget, she must use 4.4 gigabytes.
Step-by-step explanation:
Giving the following information:
Fixed cost= $57.50 per month
Variable cost= $4 per gigabyte.
She wants to keep her bill at $75.10 per month.
First, we need to establish the total cost formula:
Total cost= 57.5 + 4*x
x= number of gigabytes
Now, we isolate x:
75.1= 57.5 + 4x
17.6/4= x
4.4= x
To stay within budget, she must use 4.4 gigabytes.
Answer:
she has to use 4.4 gigabytes

Step-by-step explanation:
What is the slope of the following line? I need help asap
Answer:
-4/3
Step-by-step explanation:
it says to find the slope you do y2 - y1 / x2 - x1.
From the points, you have x1 = -3, x2 = 0, y1 = 3, y2 = -1.
Plug those in:
-1 - 3 / 0 - (-3) = -4 / 3 = -4/3
Answer:
-1-3/0-(-3)= -4/3
Step-by-step explanation:
since m=y2-y1/x2-x1 the equation would be -1-3/0-(-3) which equals to -4/0+3 which equals -4/3. since it's slope you do not simplify.

Answer:
[tex]3(x - 5) \leqslant 24 \\ 3x - 15 \leqslant 24 \\ 3x \leqslant 24 + 15 \\ 3x \leqslant 39 \\ x \leqslant \frac{39}{3} \\ x \leqslant 13[/tex]
Answer:
x ≤ 13
Step-by-step explanation:
Let's sort out the brackets first, expand them.
3(x-5) --> 3x - 15
Now our equation looks like this.
3x - 15 ≤ 24
Since we are solving the inequality, let's get the x on its own. Add the 15 to remove it from one side.
3x - 15 ≤ 24
+15 +15
3x ≤ 39
We are still trying to get x on its own so let's divide the 3, to remove it.
3x ≤ 39
÷3 ÷3
x ≤ 13
And that is the final answer!
