Answer: x = 47

because this is a right triangle

=> x + 43° = 90°

⇔ x = 90 - 43

⇔ x = 47°

Answer:

2x -8x+15=0

-6x+15=0

-6x= 15

x= 5/2

Step-by-step explanation:

Answer:

x=2.5

Step-by-step explanation:

x(2)-8×+15=0 combine like terms

-6x+15=0 subtract 15 from both sides

-6×=-15 divide by -6 on both sides

x=2.5

Step-by-step explanation:

Given that the set of data collected has an extreme value (24), a Median measure of center is more appropriate than a Mean measure.

We sort the same data collected in increasing order:

{0, 1, 2, 4, 4, 5, 5, 24}

There are 8 elements inside the set, so we check the 4th and 5th elements (closest to the center), which are 4 and 4.

Since they are equal, the Median is 4.

Our answer is Median; 4.

Answer:

median 4

Answer:

Positive exponent

Step-by-step explanation:

Like x root 1 , 2 , 3 etc

If it said negative exponent then x root -1, -2 etc etc.

Answer:

Step-by-step explanation:

When writing negative exponents as positive exponents, you move the base (the number being exponentiated) to the denominator and the exponent becomes positive.

For example: [tex]4^{-3} =1/4^3\\\\[/tex]

Answer: She made 5 liters of punch for a lunch.

Step-by-step explanation:

We know that,

1 liter = 1000 milliliters

Then, 1 milliliter = [tex]\dfrac{1}{1000}[/tex] liters

We are given that,

Mr. Peters made 5000 milliliters of fruit punch for a lunch.

i.e. in liters, it will be [tex]\dfrac{5000}{1000}[/tex] liters.

i.e. in liters, it will be 5 liters.

i.e. She made 5 liters of fruit punch for a lunch.

Hence, she made 5 liters of fruit punch for a lunch.

12.5 Step-by-step explanation: My friend helped me

The length of Kelly's old snowboard is 125 cm long.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, let we suppose that:

x = length of Kelly's old snowboard (in cm)

Then, as we know that: new snowboard is 120% longer than her old snowboard, thus:

[tex]\dfrac{x}{100} \times 120 = \text{Length of new snowboard} = 150[/tex]

or

[tex]\dfrac{x}{100} \times 120 = 150\\\\\text{Multiplying 100/120 on both the sides}\\\\x \times \dfrac{120}{100} \times \dfrac{100}{120}= 150 \times \dfrac{100}{120}\\\\x \times 1 = x = \dfrac{150 \times 100}{120}\\\\x = \dfrac{15000}{120} = 125 \: \rm cm[/tex]

Thus, the length of Kelly's old snowboard is 150 cm long.

Answer:

7/3 ft

Step-by-step explanation:

Given data

Lenght of fence= 7 miles

Amount completed= 2/3 of the total length

let us find the amount completed already = 2/3*7= 14/3 miles

Hence the length of fence remaining for completion is

=7- 14/3

=21-14/3

=7/3

Hence the amount in length undon is 7/3 ft

Options :

A. The initial number of bacteria is 7.

B. The initial of bacteria decreases at a rate of 93% each day.

C. The number of bacteria increases at a rate of 7% each day.

D. The number of bacteria at the end of one day is 360.

Answer:

C. The number of bacteria increases at a rate of 7% each day.

Step-by-step explanation:

Given the function :

f(x)=360(1.07)^x ; Number of bacteria in sample at the end of x days :

The function above represents an exponential growth function :

With the general form ; Ab^x

Where A = initial amount ;

b = growth rate

x = time

For the function :

A = initial amount of bacteria = 360

b = growth rate = (1 + r) = 1.07

If ; (1 + r) = 1.07 ; we can solve for r to obtain the daily growth rate ;

1 + r = 1.07

r = 1.07 - 1

r = 0.07

r as a percentage ;

0.07 * 100% = 7%

Answer:

y intercept is 6

Step-by-step explanation:

Given:

[tex]f(x) = 2(5^x) + 4[/tex]

Required:

Determine the y intercept

To do this, we simply set x to 0

Substitute 0 for x in [tex]f(x) = 2(5^x) + 4[/tex]

[tex]f(0) = 2(5^0) + 4[/tex]

Evaluate the exponent, [tex]5^0[/tex]

[tex]f(0) = 2(1) + 4[/tex]

Open bracket

[tex]f(0) = 2 + 4[/tex]

[tex]f(0) = 6[/tex]

Hence, the y intercept is 6

Answer:

Answer:

OB

because domain is all X values that satisfy graph. And on graph X has all +ve values going to infinity.

When the Function g is defined as g(x) = 2f(x – 4) + 3 so the domain of the function g is OB. {x|0 < x <♾}.

Since the Function g is defined as g(x) = 2f(x – 4) + 3

So here OB should be considered as the domain of the all x values should satisfied the graph. Also, on graph X it contains the positive values that goes to infinity.

Hence, When the Function g is defined as g(x) = 2f(x – 4) + 3 so the domain of the function g is OB. {x|0 < x <♾}.
