Given triangle abc with vertices A(2,-1), B(5,6), C(-1,4) as shown. Find the number of square units in the area of triangle abs in simplest form.
Answer:
The area of the triangle is 18 square units.
Step-by-step explanation:
First, we determine the lengths of segments AB, BC and AC by Pythagorean Theorem:
AB
[tex]AB = \sqrt{(5-2)^{2}+[6-(-1)]^{2}}[/tex]
[tex]AB \approx 7.616[/tex]
BC
[tex]BC = \sqrt{(-1-5)^{2}+(4-6)^{2}}[/tex]
[tex]BC \approx 6.325[/tex]
AC
[tex]AC = \sqrt{(-1-2)^{2}+[4-(-1)]^{2}}[/tex]
[tex]AC \approx 5.831[/tex]
Now we determine the area of the triangle by Heron's formula:
[tex]A = \sqrt{s\cdot (s-AB)\cdot (s-BC)\cdot (s-AC)}[/tex] (1)
[tex]s = \frac{AB+BC + AC}{2}[/tex] (2)
Where:
[tex]A[/tex] - Area of the triangle.
[tex]s[/tex] - Semiparameter.
If we know that [tex]AB \approx 7.616[/tex], [tex]BC \approx 6.325[/tex] and [tex]AC \approx 5.831[/tex], then the area of the triangle is:
[tex]s \approx 9.886[/tex]
[tex]A = 18[/tex]
The area of the triangle is 18 square units.
What is the surface area of this triangular pyramid?
Answer:
48.25
Step-by-step explanation:
This is because when finding the area of a triangle it is known as base times height then divide by 2 and since the base is a triangle, multiply 4.3 times 5 which is 21.5 and divide by 2 which is 10.75 and for the top since its also a triangle multply 5x5 which is 25 divide by 2 whicih is 12.5, but there is 3 of them so multiply by 3 and you get 37.5, then add 37.5+10.75 to get 48.25 cm^2

Smoothies weren't cutting it so we went to Red Robin to order a burger. Our bill was $5.79. Avon has a 5.25% tax and our
waitress earned a 15% tip. What was the total bill?
Answer:
$6.96
Step-by-step explanation:
5.25% of 5.79
5.79 × 5.25/100 = $0.303975 or $0.30
15% of 5.79
5.79 × 15/100 = $0.8685 or $0.87
total
$5.79 + $0.30 + $0.87 = $6.96

How much will the fruit for the fruit salad cost? Show your work.
Answer:
82.8 for the strawberries
2.49 for the bannanna
44.8 for the grapes
35.76 for the oranges
The total is 165.85
Step-by-step explanation:
The cost of fruits for fruit salad is $200.59.
Given that, fruits for fruit salad and their costs are listed below.
How to add decimal numbers?Adding decimals is similar to the usual addition of whole numbers. We know that a decimal number is a number with a whole number part and a fractional part which is separated by a decimal point.
Total cost of blueberries
= 14 × 2.48 = $34.72
Total cost of strawberries
= 23 × 3.60 = $82.8
Total cost of bananas
= 1 × 2.49 = $2.49
Total cost of grapes
= 14 × 3.20 = $44.8
Total cost of oranges
= 12 × 2.98 = $35.78
So, total cost of fruits for fruit salad
= 34.72+82.8+2.49+44.8+35.78 = 200.59
Therefore, the cost of fruits for fruit salad is $200.59.

A baseball is hit in the air. Its height above the ground is described by the function
Ht=-16t^2+45t+5, where H(t) represents the height in feet of the ball t seconds after it is hit. To the nearest hundredth of a second, for how much time will the ball be in the air? Find algebraically.
help guys plz i suck at math, also step by step is needed Branliest is the reward like always
Answer:
2.9195
Step-by-step explanation:
To find the time we need to equate the function the zero and solve for t:
[tex] { - 16t}^{2} + 45t + 5 = 0[/tex]
Using the general formula we have that:
[tex]t = \frac{ - 45 + \sqrt{ {45}^{2} - 4 ( - 16)(5)} }{2( - 16)} \\ = \frac{ - 45 + \sqrt{2345} }{ - 32} [/tex]
then:
[tex]t = \frac{ - 45 + \sqrt{2345 } }{ - 32} = - 0.107 \\ or \\ t = \frac{ - 45 - \sqrt{2345} }{ - 32} = 2.9195[/tex]
Since the time has to be positive we conclude that the ball is in the air 2.9195 seconds.

trigonometry please help! work need to be shown
Answer:
x = 5.56
Step-by-step explanation:
Apply trigonometric function to find x
Reference angle = 46°
Hypotenuse = 8
Adjacent length = x
Apply CAH:
Cos 46 = Adj/Hyp
Cos 46 = x/8
8 × Cos 46 = x
5.55726696 = x
x = 5.56 (nearest hundredth)

A stock can go up, go down, or stay unchanged. How many possibilities are there if you own 3 stocks?
Answer:
There are 27 different possible outcomes.
Step-by-step explanation:
Assuming that you have 3 different stocks:
First, we need to find the number of events and the number of possible outcomes for each event.
Here we can assume that each one of the stocks is a event, and the number of possible outcomes for each one are:
Stock 1: 3 options (up, down, stay)
Stock 2: 3 options (up, down, stay)
Stock 3: 3 options (up, down, stay)
The total number of possible outcomes is equal to the product of the numbers of options for all the events.
Then the total number of possibilities is:
C = 3*3*3 = 27

Kevin started the number pattern shown below using the rule "start with 1, multiply the previous number by 3 then add 2 to the result to get the next number." 1, 5, 17, …… What is the fifth number in her pattern?
Answer: 161
Step-by-step explanation:
From the question, the rule is that we start with 1, multiply the previous number by 3 then add 2 to the result to get the next number.
Based on the numbers already given such as 1, 5, 17, the 4th number will be:
= (17 × 3) + 2
= 51 + 2
= 53
The 5th number will be:
= (53 × 3) + 2
= 159 + 2
= 161

Step-by-step explanation:
If the terminal side of angle θ goes through the point (−313√13,−213√13) on the unit circle, then what is cos(θ)?
Answer
cos(θ) = –313√(13)
Step-by-step explanation:
There is a rule we are to establish first to get the answer right.
If the terminal side of an angle θ in standard position intersects a unit circle A(x, y), then cos(θ) = x and sin(θ) = y.
Therefore, given that the terminal side of angle θ goes through the point (−313√13,−213√13) on the unit circle:
cos(θ) = –313√(13)
