To begin a bacteria study, a petri dish had 2400 bacteria cells. Each hour since, the number of cells has increased by 3.6%.
Lett be the number of hours since the start of the study. Let y be the number of bacteria cells.
Write an exponential function showing the relationship between y and t
Answer:
Y=2400*3.6^t
Step-by-step explanation:
y=a*b^x
a is the initial amount
b is the decrease/increase rate
x is the amount of time

What is the equation of a circle with a center located at (-3, 4) and a diameter of 14?
Answer: (x + 3)^2 + (y - 4)^2 = 49
Step-by-step explanation:
The equation of a circle given the center and radius: (x - h)^2 + (y - k)^2 = r^2
Given: center (-3,4) ; h = -3 and k = 4
diameter = 14
To find the radius: divide the diameter by 2 = 14/2 = 7 = r
Center: (-3,4) and radius: 7
Equation of a circle: (x - h)^2 + (y - k) ^2 = r^2
Substitute h = -3, k = 4, r = 7
(x - (-3))^2 + (y - 4)^2 = 7^2
Answer:
Equation of the circle: (x + 3)^2 + (y - 4)^2 = 49
Which one would it be?
Answer:
424
Step-by-step explanation:
If y = 424
and x is the number that exists as x already
y would equal to: 424

The juice box below is 6 inches tall, 2 inches wide and 4 inches long. Find the surface area and volume of the juice box. please need help asap will give lots of points
Answer:
104
Step-by-step explanation:
A=2(wl+hl+hw)
Answer:
Solution given:
length[l]=5in
base[w]=2in
height[h]=6in
we have
surface area=2(lw×lh×wh)=2(5×2+5×6+2×6)
=104in²is surface area of juice box.
again
we have
volume =lwh=5×2×6
=60in³ is volume of juice box.

Answer:
k = 5.25
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of proportionality
To find k use the condition y = 84 and x = 16 , then
84 = 16k ( divide both sides by 16 )
5.25 = k
Line AB connects the ends of the horseshoe and passes through the stake at point (x,y). If the equation for line AB is x = 6, which of these might be the coordinates of the stake? Assume that all the points lie in a rectangular coordinate system.
https://portal.achieve3000.com/images/uploads/m910_teensatcamp09.gif
Answer:
(6,0), (6,1), (6,2) (6,3)...
Step-by-step explanation:
x = 6
This means that 6 is the x-intercept since this is the equation for a verticle line, this means that x remains in 6 and y is the only number that moves so the AB stake point could be any number where x is 6, it could even be (6,0),
(6,1) e.t.c.
You have $20 to spend for cupcakes. If each cupcake costs $4, write and solve an inequality to show the maximum number of cupcakes you can buy.
Given the diagram below, find the height of the shorter tree.
16.2 m
7 m
13 m
19.7 m
Answer:
h = 13 m
Step-by-step explanation:
The triangles are similar, so the ratios of corresponding sides are equal, that is
[tex]\frac{h}{39}[/tex] = [tex]\frac{16}{48}[/tex] = [tex]\frac{1}{3}[/tex] ( cross- multiply )
3h = 39 ( divide noth sides by 3 )
h = 13

Write the equation for a circle with a center at (-7 , -4) and a radius of 2.
Answer:
(x + 7)² + (y + 4) ² = 2²
Step-by-step explanation:
Start with the standard equation of a circle with center at (h, k) and radius r:
(x - h)² + (y - k)² = r²
Here we are given that h = -7, k = -4 and r = 2, and so we obtain:
(x + 7)² + (y + 4) ² = 2²
Step-by-step explanation:
The answer is above, as well as the equation used to get to the answer.

Answer:
The answer is 24cm²
Step-by-step explanation:
The triangle area is given by A*½ and we get 4*2*½=6
Rectangle one is given as L*W and we solve 3*4= 12
Rectangle two is solved as L*W as well so we solved 1.5*4= 6
and we get 24cm²
