Answer:

895 million camera phones

Step-by-step explanation:

Since the function is modeled by;

y=1.28e^1.31x

Now between 1997 - 2002 we have 5 years. This means that x =5. So we have to substitute x = 5 into the function to obtain the number of camera phones shipped in 2002.

Therefore;

y=1.28e^1.31(5)

y = 895 million camera phones

Answer:

310 meter square

Step-by-step explanation:

Area of a rectangle = length x width

Area of the rectangular park = 18 3/5 x 50/3

                                                = 93/5 x 50/3

                                                = 930/3

                                                = 310 meter square

Answer:

(h-g)(x) = x^3 - 5x -5

Step-by-step explanation:

h(x)= x^3 - 2x and g(x)= 3x +5

(h-g)(x) = x^3 - 2x -( 3x +5)

Distribute

(h-g)(x) = x^3 - 2x - 3x -5

Combine

(h-g)(x) = x^3 - 5x -5

Step-by-step explanation:

General line equation: y = mx + c.

2y + 3x = 5

2y = -3x + 5

y = -1.5x + 2.5

Hence m = -1.5 and c = 2.5.

[tex]\tt m=-\dfrac{3}{2}\\\\c=\dfrac{5}{2}[/tex]

Given

The line equation

2y+3x=5

Required

m(gradient) and c(constant)

Solution

The two-variable linear equation is a linear equation that has 2 variables and the exponent is one

ax+by=c

We change the equation in standard form  : y = mx + c

[tex]\tt 2y=-3x+5\\\\y=-\dfrac{3}{2}x+\dfrac{5}{2}[/tex]

Gradient :

[tex]\tt -\dfrac{3}{2}[/tex]

Constant :

Alisha can mow the lawn 5 times before refilling the container.

Step-by-step explanation:

We have the total amount of gas to mow the lawn and the amount needed to mow one lawn, so we need to divide.

3 3/4 divided by 3/4 =5

Therefore she can mow the lawn 5 times before refilling the container.

Answer:

The statement which is not true about the sample is;

The sample of 10 plants was a census of the corn plants

Step-by-step explanation:

The statement out of the given statements which is not true about the sample is "The sample of 10 plants was a census of the corn plants"

The 10 unique number corn which the farmer randomly selects of which he then count the number of ears in the corn and multiply by 100 so as to quickly arrive at an estimate of the total number of ears of corn for the crop, without individually counting the ears on each plant from the 100 plants

A census is a counting and individual enumeration procedure to collect and record characteristic information and details of the all the members that make up a given population

Therefore, the farmer is finding an estimate of the number of ears of in the plants rather than taking a census of the ears of corn on each plants in the population of 100 plants

Answer:

The sample of 10 plants was a census of the corn plants.

Answer:

40%

Step-by-step explanation:

18+12+20=50

20/50×100=

40%

The percentage of the students who chose vanilla as their favorite ice cream flavor will be 40%.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

The rundown underneath shows the consequences of a review of the most loved frozen yogurt flavors among center school understudies.

The total number of students is given as,

Total = 18 + 12 + 20

Total = 50

Then the percentage of the students who chose vanilla as their favorite ice cream flavor will be given as,

P = (20 / 50) x 100

P = 0.40 x 100

P = 40%

The percentage of the students who chose vanilla as their favorite ice cream flavor will be 40%.

Answer:

Step-by-step explanation:

this is a 30 60 90 triangle.. b/c 2 of the angles are given and you know the total is 180 around a triangle so the last angle is 30

also you know the hypotenuse of this triangle is 10 so use cos and sin to figure out the other sides

Use SOH CAH TOA to remember how the sin and cos functions fit on the triangle

CAH = Cos(Ф) = Adj/ Hyp   we are given the Ф angle and we know the hypotenuse so solve for the Adj side

Hyp*Cos(Ф)= Adj

10 * Cos(60) = Adj

5 = Adj = y

Use Sin for the other side  and the mnemonic to remember how it fits on the triangle and solve for the Opposite , since we don't know that .. yet

Sin(Ф) = Opp/ Hyp

Hyp * Sin (Ф) = Opp

10 * Sin(60) = Opp

10 *[tex]\sqrt{3}[/tex]/2 = Opp

5*[tex]\sqrt{3}[/tex] = Opp = x

:) I know Sin(60) = [tex]\sqrt{3}[/tex]/2  from a table and also my memory .. know that one from memory

Answer:

Step-by-step explanation:

Given that:

Number of pizzas made = x

Total pizza sauce left = 1/3 L

Amount of sauce used on each pizza made = 1/6 L

Hence , Number of pizza's made ;

(Total pizza sauce left / amount of sauce used per pizza made)

= (1/3 L) ÷ (1/6)L

= 1/3 * 6/ 1

=6 / 3

= 2

Hence, number of pizza's made = 2

Answer:

(a) 40 m

(b) 4 seconds

(c) 1 second, 45 m

(d) 1 second

Step-by-step explanation:

The given height as a function of height is

[tex]h= -5t^2+10t+40[/tex]

where t is the time in seconds and h is the height, in meters.

(a) At the starting time, t=0, the arrow is at the platform.

So, putting t=0, to get the height of the platform

[tex]h= -5(0)^2+10(0)+40 = 40[/tex] m

(b) For determining the length of time the arrow is in the air, first t determining the value of t for which h=0, we have

[tex]-5t^2+10t+40=0 \\\\-t^2+2t+8=0 \\\\-t^2+4t-2t+8=0 \\\\-t(t-4)-2(t-4)=0 \\\\(-t-2)(t-4)=0 \\\\[/tex]

t=-2, t=4  

Mathematically, the value of t for which the arrow is in the air is the time from -2 to 4 seconds.

But the arrow was at the platform at time t=0. So, neglecting the negative time, the time for which the arrow was in the air is the time from 0 to 4 seconds, i.e 4 seconds.

(c) Mathematically, the value of t for which the arrow is in the air is the time from t=-2 to t=4 seconds. So, in the middle of time, i.e at t=1 second the arrow will reach the maximum height.

Putting t=1 to get the maximum height, we have

[tex]h=-5(1)^2+10(1)+40[/tex]

h=-5+10+40

h=45 m

Therefore, the maximum height is 45 m at t=1 second.

(d) Referinf option (c), at the time, t=1 second, the arrow has a height of exactly 45m above the ground

Answer:

-6 is the answer.

Step-by-step explanation:

4x - 5 = x - 23

or, 4x - x = -23 + 5

or, 3x = -18

or, x = -18/3

therefore, x = -6

Answer:

the answer is (3)

Step-by-step explanation:

4x - 5 = x - 23

4x = x - 23 + 5

4x = x - 18

4x - x = -18

3x = -18

Step-by-step explanation:

In this question, the graph file is missing so, its solution can be defined as follows:

When the bag includes 20 marbles, each will be drawn 5% of the time on average.  

The bar chart shows that nearly 50% of the workforce red marbles are drawn, and about 25% of the time blue and white marbles are drawn. so, the equation is:

[tex]\to \frac{50\%}{5\%}= \frac{50 \times 100}{5\times 100}=\frac{50}{5} = 10 \ red \ marbles\\\\\to \frac{25\%}{5\%}= \frac{25 \times 100}{5\times 100}=\frac{25}{5} = 5\ blue \ marbles[/tex]
