Initially, there were only 86 weeds in the garden. The weeds grew at a rate of 29% each week. The following function represents

the weekly weed growth: f(x) = 86(1.29)x. Rewrite the function to show how quickly the weeds grow each day.
A.f(x) = 86(1.04)x; grows approximately at a rate of 0.4% daily
B.f(x) = 86(1.04)7x; grows approximately at a rate of 4% daily
C.f(x) = 86(1.29)7x; grows approximately at a rate of 20% daily
D.f(x) = 86(1.297)x; grows approximately at a rate of 2% daily

Step-by-step answer:

The base of the exponential function is 1.29 for 7 days, as in

f(x) = 86*(1.29)^x

The new rate for days can be calculated by dividing x by 7 (where x remains the number of weeks), namely

f(x) = 86*1.29^(x/7)

Using the law of exponents, b^(x/a) = b^(x*(1/a)) = (b^(1/a))^x

we simplify by putting b=1.29, a=7 to get

f(x) = 86*(1.29^(1/7))^x

f(x) = 86*(1.037)^x      since 1.29^(1/7) evaluates to 1.037

Rounding 1.037 to 1.04 we get a (VERY) approximate function

f(x) = 86 * (1.04^x)

1.04 is very approximate because 1.04^7 is supposed to get back 1.29, but it is actually 1.316, while 1.037^7 gives 1.2896, much closer to 1.29.

A right triangular prism has a height of 26 cm and base edges of 10 cm, 24 cm, and 26 cm. What is the lateral area of the prism?
horrorfan [7]
The lateral area is 1560 cm².

The lateral area is the area of the lateral faces (the faces that are not bases).  The dimensions of these are:
24 by 26
10 by 26
26 by 26

These are all rectangles.  The area of each rectangle is given by length * width:
24*26 = 624
10*26 = 260
26*26 =676

624+260+676=1560

Distance=speed times time
distance/time=speed

distance=538
time=9 and 15mins
60mins=1hr
15/60=1/4=0.25

time=9.25hr


distance/time=538/9.25=58.162mph

What is the measure of (2x+94) = (8x+10)
Anna [14]
I subtract 2x  to 8x that is equal to 6x; then I subtract 10 from right to left. So 94-10 equal 84. Now you got 6x=84, divide 6 both side and you got the answer. 
 
The answer is x= 14

Answer:

<u>30 people </u>

Step-by-step explanation:

The question is as following:

800g pineapple 4 egg whites 1/2 lemon 100g caster sugar

Dan makes pineapple sherbet he uses 2 1/2 lemons

work out how many people he makes pineapple sherbet for?

=======================================================

1/2 lemon needed for pineapple sherbet for 6 people

2 1/2 lemons needed for pineapple sherbet for <u>x</u> people

1/2 : 6 = 2 1/2 : x

∴ x = ( 6 * 2 1/2 ) ÷ (1/2)

x = 6 * 5/2 * 2 = 30 people

<u>So, he make the pineapple sherbet for 30 people </u>
