Answer:

Either A or D, but the answer is [tex]f(x) = 3^x[/tex].

Step-by-step explanation:

We can check for exponential growth by checking for an [tex]x[/tex] in the exponent of a constant value in the function, which is this case for [tex]f(x) = 3^x[/tex].

f(x) = x + 3 function represents exponential growth. So the correct option is option is c.

An exponential function is a arithmetic function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is know the base of the function and it will be greater than 0.

An exponential function is explain by the formula f(x) = ax, where the input variable x take place as an exponent.

The exponential curve turn on the exponential function and it depends on the value of the x.

The exponential function is an main arithmetic function which is of the form

f(x) = ax

Exponential Growth

In Exponential Growth, the quantity grow very slowly at first, and then quickly. The rate of change growth over time. The rate of growth becomes faster as time passes. The quick growth is meant to be an “exponential increase”. The formula to explain the exponential growth is:

y = a ( 1+ r )x

Where r is the growth percentage.

Therefore, f(x) = x + 3 is a function represents exponential growth.

Answer:

(x, y) = (-16/5, 13[tex]\frac{1}{5}[/tex])

Step-by-step explanation:

4x + 9y = 24

x + y = 10 $\Rightarrow$ x = 10 - y

Substituting the value of x (second equation) into the first equation, we get:

4 * (10 - y) + 9y = 24

40 - 4y + 9y = 24

5y = -16

y = -16/5.

So, x = 10 - (-16/5) = 10 + 3[tex]\frac{1}{5}[/tex] = 13[tex]\frac{1}{5}[/tex]

sin=0,98

Sry when Its wrong

Answer:

sin• = √13/7

tan•= -√13/4

Step-by-step explanation:

sin2•+ cos2• = 1

sin• = √1-cos2•

sin•= √1-(-4/7)2

sin•= √1-16/49

sin•= √ 49-16/49

sin•= √ 13/ 49

sin•= √13/7

tan• = sin•\cos•

= √13/7/-4/7

= -√13/4

Answer:

if 'c' equals number of counters, the answer is 6c + 5

Step-by-step explanation:

david has 'c'

lisa has '5+c'

samia has '4c'

add all terms together:  c + 5 + c + 4c = 6c + 5

The formula for the total number of counters in terms of x is T = 6x + 5

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Let's start by expressing the number of counters Lisa has in terms of x. We know that Lisa has 5 more counters than David, so:

Lisa = David + 5

Lisa = x + 5

Next, we need to express the number of counters Samia has in terms of x. We know that Samia has 4 times as many counters as David, so:

Samia = 4 × David

Samia = 4x

Finally, we can express the total number of counters in terms of x by adding up the number of counters each person has:

T = David + Lisa + Samia

T = x + (x + 5) + 4x

T = 6x + 5

Therefore, the formula for the total number of counters in terms of x is T = 6x + 5.

Answer: $275

Step-by-step explanation:

The mean of the radio price is $275 or 27500 cents

Given,

Price of used original radio for a 1955 Thunderbird:

$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200

We need to find the mean of these prices.

And round to nearest cent.

The mean is the average of all the given sets of values.

Example:

1,2,3,4

Mean = (1+2+3+4) / 4 = 10/4 = 2.5

Find the sum

$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200

Sum=(210+210+320+200+300+10+340+300+245+325+700+250+240+200)

Sum = 3850

Find the number of prices.

= 14 prices

Find the mean.

= 3850 / 14

= 275

The mean radio price is $275.

Converting into cents.

$1 = 100 cents

$275 = 27500 cents

Thus the mean of the radio price is $275 or 27500 cents

~Hoped this helped~

Brainly, please?

Answer:

part 1:

1) AB = BC = 10

2) DE = sqrt(10² - 9²) = sqrt(19)

3) CED = 90⁰

4) BCD = (90⁰ - 53⁰).2 = 74⁰

part 2:

because FGHJ is a rhombus

=> GK = KJ

<=> 3x + 1 = x + 9

<=> 2x = 8

<=> x = 4

and we have:

GHK + FGK = 90⁰

<=> (4y - 8)/2 + y + 4 = 90⁰

<=> 2y - 4 + y + 4 = 90⁰

<=> 3y = 90⁰

<=> y = 30

5) with x = 4 => GJ = 2KJ = 2.(4 + 9) = 26

6) JK = 4 + 9 = 13

7) with y = 30, HFJ = 90 - FGK = 90 - 34 = 56⁰

8) HJF = 2.FGK = 2.34 = 68⁰

part 3:

because MNLO is rectangle

=> MP = PO

<=> 5a - 7 = 2a + 8

<=> 3a = 15

<=> a = 5

9) with a = 5, MO = 2.PO = 2.(2.5 + 8) = 2.18 = 36

10) NP = PO = 2.5 + 8 = 18

11) LM² = LN² - MN² = MO² - 26² = 36² - 26² = 620

=> LM = 2sqrt(156) = 24,9

12) tan NMO = NO/MN = LM/MN = 24.9/26

=> NMO = 43,8⁰

part 4:

because RSTU is square

=> SR = RU

=> 2k + 7 = 3k - 2

<=> k = 9

with k = 9 =>RU = SR = 2.9 + 7 = 25

13) RV = 1/2.SU = 1/2.sqrt(25² + 25²) = 17,7

14) SU = 2RV = 2.17,7 = 35,4

15) perimeter RSTU = 25.4 = 100

16) area RSTU = 25² = 625

Answer: 0.1056

Step-by-step explanation:

Given: Chipotle Burritos are normal distributed with

Mean =  200 mm

Standard deviation = 8 mm

Let x be the length of a random burrito.

The probability that a burrito picked at random is shorter than 190mm will be :

[tex]P(x<190)=P(\dfrac{x-\mu}{\sigma}<\dfrac{190-200}{8})\\\\=P(z<-1.25)\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(z<1.25)\\\\=1-0.8944\\\\=0.1056[/tex]

Hence, the probability that a burrito picked at random is shorter than 190mm is 0.1056.

Answer:

1. AB= 8.94,

2. AB= 7.28

3. AB= 16.4

4. AB= 19.21

Step-by-step explanation:

This is fun! Well you have to find the (1,4) (or point e) point and count the distance to the other points point a and point b.

4 units from a to e and 8 b to e

a² + b² = c²

8² + 4² = c²

64 +16 = c

√80 = √c²

8.94 = c

It dose not matter which units you plug in for a and b but c has to be the long side of the triangle/ hypotonuse.

Follow the same steps for the rest of the problems.

On proplems 3 and 4 plot points first you can subtract the x-x and y-y as a short cut to find the units.

Given:

A circle with center O.

[tex]m\angle MOP=45^\circ, m\angle PON=85^\circ[/tex].

To find:

The measure of arc MN.

Solution:

We know that,

[tex]m\angle MON=m\angle MOP+m\angle PON[/tex]

[tex]m\angle MON=45^\circ+85^\circ[/tex]

[tex]m\angle MON=130^\circ[/tex]

The central angles in equal to the measure of the corresponding arc.

[tex]Arc(MN)=m\angle MON[/tex]

[tex]Arc(MN)=130^\circ[/tex]

Therefore, the measure of arc MN is 130 degrees.
