What is the surface area
Answer:
red) area = 59.2 km²
Step-by-step explanation:
area of bottom 4 x 4 = 16
area of 4 sides = 4 (1/2)(4)(5.4) = 43.2
16 + 432 = 59.2 km²
Answer:
Step-by-step explanation:
lateral area = 2(base)(slant height) = 2·4·2 = 16 km²
base area = base² = 4² = 16 km²
surface area = 16 + 16 = 32 km²
Let f(x)=18/1+3^e-0.1x What is the point of maximum growth rate for the logistic function f(x)? Show all work. Round your answer to the nearest hundredth
Answer:
(0, 4.5)
Step-by-step explanation:
*The equation can be put into Desmos, to find the point, but the work to prove it is here*
f(x)=c/1+Ae^-Bx
Y=C
C=18 A=3 -B=-0.1
*Replace x with 0 in the equation, so you know 0 is the x value, and it leads you to the y value*
f(0)=18/1+3e^-o.1(0)
= 18/1+3e^0
=18/1+3(1)
=18/1+3
=18/4
=4.5
x=0 y=4.5
Maximum growth rate = (x,y) --> (0, 4.5)

Members of a soccer team raised $1719 to go to a tournament. They rented a bus for
$1051.50 and budgeted $44.50 per player for meals. Write and solve an equation
which can be used to determine z, the number of players the team can bring to the
tournament.
Answer:
44.5x + 1051.5 = 1719
x = 15
Step-by-step explanation:
DeltaMath
The number of players the team can bring to the tournament is 15.
Given:
The total amount of money raised by the soccer team = $1719
Amount to rent the bus = $1051.50
Amount budgeted for each player's meal = $44.50
To find:
Equation and the number of players the team can bring to the tournament
Solution:
The number of players the team can bring to the tournament = z
Amount budgeted for each player's meal = $44.50
Total amount needed for z number of players' meals = $44.50z
Amount to rent the bus = $1051.50
The total amount of money raised by the soccer team = $1719
The equation for numbers of players will be written as:
[tex]\$44.50z+ \$1051.50= \$1719\\\$44.50z= \$1719- \$1051.50\\\$44.50z=\$667.50\\z=\frac{\$667.50}{\$44.50}=15[/tex]
The number of players the team can bring to the tournament is 15.

Luke bought his car for £18000
Work out how much his car will be worth after 4 years.
Answer:
£9360
Step-by-step explanation:
£18000× 12 ÷100 = £2160
£2160 × 4 = £8640
£18000 - £8640 = £9360

In triangle RST the vertices have coordinates of R(-1,10),S(5,4)and T (-4,-2). If the midpoints of side RS and RT were connected with a segment, what would the slope of this segment be?
Plz helppp
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Midpoint of a line segment joining points [tex](x,y)[/tex] and [tex](u,v)[/tex] is given by [tex](\frac{x+u}{2},\frac{y+v}{2} )[/tex]
Points are R(-1,10),S(5,4)and T (-4,-2).
Midpoint of RS = [tex](\frac{-1+5}{2},\frac{10+4}{2} )=(\frac{4}{2},\frac{14}{2} )=(2,7 )[/tex]
Midpoint of RT = [tex](\frac{-1-4}{2},\frac{10-2}{2} )=(\frac{-5}{2},\frac{8}{2} )=(\frac{-5}{2},4)[/tex]
Slope of a line joining points [tex](a,b)[/tex] and [tex](c,d)[/tex] is given by [tex]\frac{d-b}{c-a}[/tex]
Slope of line joining midpoints of side RS and RT = [tex](\frac{4-7}{\frac{-5}{2}-2 })=(\frac{-3}{\frac{-9}{2} })=\frac{2}{3}[/tex]

The slope of the line is _______.
A. positive
B. negative
C. zero
D. undefined
Answer:
the slope is POSITIVE (answer A)
Step-by-step explanation:
The line goes through: (-1, -2) and ( 2, 1)
Then the slope can be calculated as:
slope = (y2 - y1) / (x2 - x1)
in our case:
slope = (1 - -2) / (2 - -1) = (1 + 2) / (2 + 1) = 3 / 3 = 1
Therefore, the slope is POSITIVE (answer A)

Use the graph to find estimates for

i) 4x2 - 4x – 1 = 0

Step-by-step explanation:

Factor the expression using the GCF. 58+28=
Answer:
2(29+14)
Step-by-step explanation:
Given function:
To find the GCF of 58+28..Find the GCF of 58+28:
[tex]58=29[/tex]·[tex]2[/tex] [tex]28=14[/tex]·[tex]2[/tex]Rewrite:
[tex]2(29+14)[/tex]Therefore, using GCF, the new expression would be 2(29+14)..
The expression 58 + 28 can be factorized as 2 (29 + 14).
What is GCF?GCF which is the abbreviated form for Greatest Common Factor of two numbers, as the name implies, is the greatest common factor of both the numbers.
GCF of two numbers can be found using prime factorization.
Given the expression 58 + 28.
To find the GCF of two numbers, list the prime factors of these two numbers.
58 = 2 × 29
28 = 2 × 14 = 2 × 2 × 7
The only common factor is 2.
So the greatest common factor is 2.
58 + 28 = (2 × 29) + (2 × 14)
Taking the common factor of 2 outside the brackets,
58 + 28 = 2 (29 + 14)
Hence the expression 58 + 28 can be factorized as 2 (29 + 14) using the greatest common factor.
