Answer:
-4,-1,4,11
Step-by-step explanation:
f(n)=n^2-5
Let n= 1
f(1)=1^2-5 = 1-5 = -4
Let n= 2
f(2)=2^2-5 = 4-5 = -1
Let n= 3
f(3)=3^2-5 = 9-5 = 4
Let n= 4
f(4)=4^2-5 = 16-5 = 11

hazel prepared 6/8 liter os juice and 5/8 liter of guyabano juice.how many liters of juice did she prepare in all
Answer:
Step-by-step explanation:
i believe you just have to add the fractions together since the denominator are the same :)
[tex]\frac{6}{8} + \frac{5}{8} = \frac{6 + 5}{8} = \frac{11}{8}[/tex]
So in total Hazel can produce [tex]\frac{11}{8}[/tex] Liters of juice

Calculate the pay of the following day of a wage of $ 11/hour.
Answer:
93.5 dollars during Monday.
Step-by-step explanation:
Morning: 12:15 - 8 = 4hours 15 minutes
Afternoon: 17:15 - 13 = 4 hours 15 minutes
Total Time working = 4 hours 15 minutes + 4 hours 15 minutes
Total time working = 8 hours 30 minutes
30 minutes = 1/2 hour = 0.5 hours
Total time = 8.5 hours
Wage = 8.5 * 11 = 93.5 dollars for Monday.

m<6 = (2x-5)°
m<4 = (x+5)°
9514 1404 393
Answer:
∠3 = 115°
Step-by-step explanation:
Angles 4 and 6 are "same-side interior angles", so are supplementary.
∠4 +∠6 = 180°
(x +5) +(2x -5) = 180
3x = 180
x = 60
The angles marked 3 and 6 are alternate interior angles, so are congruent. The measure of angle 3 is ...
∠3 = ∠6 = (2x -5)° = (2(60) -5)°
∠3 = 115°

Robert is designing hexagonal tiles that are made up of 12 identical right triangles, as shown. Write three equations robert can use the find the area A of the hexagonal tile in square centimeters.
Given:- Hexagon is made up of identical 12 triangles Sides of triangle :- 5cm,4cm,3cmTo Find:- 3 Equations for finding the area of the triangle Answer:-First method:-we know 12 triangles make up hexagon so we can say
12× Area of triangle = Area of hexagon
[tex]12 \times ( \frac{1}{2} \times base \times height) = area \: of \: hexagon[/tex]
[tex]12 \times \frac{1}{2} \times 3 \times 4 = area \: of \: hexagon \\ 12 \times 3 \times 2 = area \: of \: hexagon \\ 12 \times 6 = area \: of \: hexagon \\ 72cm {}^{2} = area \: of \: hexagon[/tex]
Second method:-we can see that there is a rectangle in the middle of the hexagon and 4 triangles (identical ) on 2 sides
According to question:-
sides of rectangle :- 8 cm and 6cmside of triangle is sameso area of hexagon= area of square+ 4 area of triangle
[tex]( l \times b ) + (4( \frac{1}{2} \times b \times h)) = area \: of \: hexagon[/tex]
[tex] (8 \times 6 ) + 4(\frac{1}{2} \times 4 \times 3) = area \: of \: hexagon \\ 48 + 24= area \: of \: hexagon \\ 72 {cm}^{2} = area \: of \: hexagon[/tex]
Third method:-we can see 2 square at the sides of the 4 triangle at the middle so we can say
side of square = 5cmsides of triangle = 4cm ,3cmArea of hexagon =4× area of triangle + 2 area of square
[tex]area \: of \: hexagon = (4\frac{1 }{2} × 4×3)+2(5×5) [/tex]
[tex]area \: of \: hexagon = 24+ 50 \\ area \: of \: hexagon = 74cm² \\ area \: of \: hexagon = 72 cm ² approx [/tex]
This approximation turn out bez in your question the area of 4 identical triangle is not equal to square formed by them
4 area of triangle = area of square
4×6 = 24 cm² not equal to 5² = 25 cm²
thats why there is approximation of 2 cm²
Please answer this by midnight I need it for Algebra 3 and I don't want to fail please
The length of the arc is about 1.758 cm.
First, we need to determine the size of the angle. If we have pi/5 radians, we can convert that to 36 degrees, because pi radians is 180 degrees. Now, we know the measure of the arc is 36 degrees. 36 degrees out of 360 degrees is 10%.
Our arc is 10% of the circumference of the circle.
The circumference is 2(pi)r or 2(3.14)2.8 = 17.58 cm
Now, multiply 17.58 by 0.1 to get a total of 1.758 cm.

Select all that apply. A rectangular prism has a volume of 96 cubic inches. Select the possible measurements for the base area and height of the prism.
This should be simple, just simply multiply the area of base with height.
A - 24 * 4 = 96 ft³
B - 9.5 * 5 = 47.5 ft³
C - 16 * 6 = 96 ft³
D - 48 * 2 = 96 ft³
E - 9 * 5.3 = 47.7 ft³
Therefore, only option A, C, D is correct.

Answer
148/26 = 5.69 min/mile
Step-by-step explanation:
Unit rate miles per minute = 26/148 = 0.175= 0.176 miles per minute (rounded)
If you want minutes per mile 148/26 = 5.69 min/mile
Tom started an entertainment company. The net value of the company (in thousands of dollars) ttt months after its creation is modeled by v(t)=4t^2-24t-28v(t)=4t 2 −24t−28v, left parenthesis, t, right parenthesis, equals, 4, t, squared, minus, 24, t, minus, 28 Tom wants to know when his company will be at its lowest net value. 1) Rewrite the function in a different form (factored or vertex) where the answer appears as a number in the equation. v(t)=v(t)=v, left parenthesis, t, right parenthesis, equals 2) How many months after its creation does the company reach its lowest net value? months
Answer:
4(t-3)^2-64
3 months
Step-by-step explanation:
1) Vertex form of the equation of the parabola is [tex]v(t)=4(t-3)^2-64[/tex]
2)3 months after its creation the company will reach its lowest net value.
The net value of the company after t months is given as:
[tex]v(t) = 4t^2-24t-28[/tex]
The above parabolic equation can be written as
[tex]v(t)=4(t^2-6t+9)-64[/tex]........(1)
What is the general equation of a parabola with vertex (h,k)?The general equation of a parabola is:
[tex]y = a(x-h)^2 +k[/tex]
where (h,k) is the vertex of the parabola.
So, (1) can be written in the vertex form as
[tex]v(t)=4(t-3)^2-64[/tex]
So, the vertex of the given parabola is (3, -64).
[tex]v'(t) = 8t - 24[/tex]
[tex]v''(t) =8[/tex]
So, from the second derivative test
t value corresponding to v'(t) =0 will give minimum value
[tex]8t-24=0[/tex]
[tex]t=3[/tex]
So, 3 months after its creation the company will reach its lowest net value.
Therefore, 1) Vertex form of the equation of the parabola is [tex]v(t)=4(t-3)^2-64[/tex]
2)3 months after its creation the company will reach its lowest net value.

At the beginning of the year, John had $40 in savings and saved an additional $13 each week thereafter. Isaac started the year with $80 and saved $9 every week. Let 'J' represent the amount of money John has saved tt weeks after the beginning of the year and let 'I' represent the amount of money Isaac has saved tt weeks after the beginning of the year. Write an equation for each situation, in terms of t, and determine the number of weeks after the beginning of the year until John and Isaac have the same amount of money saved.
Answer:
10 weeks
Step-by-step explanation:
Let’s replace ‘t’ with numbers going up starting from 0 on both sides of the equation. Repeat until you get to 10 and you see that both are equal at $170 has been saved after 10 weeks.
John’s equation: 40 (y intercept) + 13t (saved per week)
Issac’s: 80 (y intercept) + 9t (amount saved per week)
The y-intercept represents the amount of money already saved up.
