Expand each logarithmic expression

Answer:

No its not

Step-by-step explanation:

Answer:

No, 0.85 is greater.

Step-by-step explanation:

Imagine a number line, with one at the end and 0.1 at the other end. With .85, It would be closer to one, with 0.6 being behind 0.85. The only other reason that 0.6 is greater than 0.85 is if they are converted to fractions.

Answer:

10 and -10

Step-by-step explanation:

difference of two squares:

x² - 100 = 0

(x + 10)(x - 10) = 0

x + 10 = 0;  x = -10

x - 10 = 0;  x = 10

Answer:

  LA = 20π square units

  SA = 36π square units

  V = 16π cubic units

Step-by-step explanation:

The value of the radius is needed before any area calculations can be done. It can be found from the Pythagorean theorem:

  r² + 3² = 5²

  r = √(25 -9) = 4

__

The lateral area is given by the formula ...

  LA = πrs . . . . . where r is the radius and s is the slant height

  LA = π(4)(5)

  LA = 20π square units

__

The surface area is the sum of the lateral area and the base area. The latter is the area of a circle of radius 4.

  SA = πr² + LA

  SA = π(4²) +20π = 16π +20π

  SA = 36π square units

__

The volume is given by the formula ...

  V = 1/3πr²h

  V = 1/3π(4²)(3) = 16π

The volume is 16π cubic units.

Answer:

After 12 years Bob will have $ 4,508.80 in his account.

Step-by-step explanation:

Given that Bob wants to invest his $ 3000 in an account that gets 3.4% interest rate compounded monthly, to determine how much money will he have after 12 years the following calculation must be performed:

3000 x (1 + 0.034 / 12) ^ 12x12 = X

3000 x (1 + 0.0028333) ^ 144 = X

3000 x 1.0028333 ^ 144 = X

3000 x 1.502932 = X

4,508.80 = X

Therefore, after 12 years Bob will have $ 4,508.80 in his account.

Answer:Given : points G and I have coordinates (6,4) and (3,2)

To Find : Use  Pythagorean theorem  to calculate the straight line distance between points G and I

Solution:

points G and I have coordinates (6,4) and (3,2)

Draw a line parallel to y axis passing through G

Draw a line parallel to x axis passing through I

Intersection point K ( 6 , 2)

IK = 6 - 3 = 3

GK = 4 -2  = 2

ΔIKG right angled triangle

Pythagoras' theorem: square on the hypotenuse of a right-angled triangle is equal to the sum of the squares of the other two perpendicular sides.  

GI² = IK² + GK²

=>  GI²  = 3² + 2²

=>  GI²  = 13

=> GI = √13

using distance formula

G (6,4) and I (3,2)

= √(6 - 3)² + (4 - 2)²

= √3² + 2²

= √9 + 4

= √13

Answer:

[tex] \displaystyle \rm {x}=5 \ln \bigg(\frac{6}{5} \bigg) \: or \: 0.91(approx)[/tex]

Step-by-step explanation:

we are given a logarithmic equation

[tex] \displaystyle {5e}^{0.2x} = 6[/tex]

we want to figure out x

remember that,

[tex] \ln( {e}^{x} ) = x[/tex]

therefore to use the above formula with our given equation

divide both sides by 5:

[tex] \displaystyle \frac{{5e}^{0.2x} }{5}= \frac{6}{5} [/tex]

[tex] \displaystyle {e}^{0.2x} = \frac{6}{5} [/tex]

take In both sides:

[tex] \displaystyle \ln({e}^{0.2x} )= \ln \bigg(\frac{6}{5} \bigg)[/tex]

by using the formula we acquire

[tex] \displaystyle 0.2x= \ln \bigg(\frac{6}{5} \bigg)[/tex]

we can rewrite left hand side as fraction

[tex] \displaystyle \frac{1}{5} x= \ln \bigg(\frac{6}{5} \bigg)[/tex]

multiply both sides by 5

[tex] \displaystyle x=5 \ln \bigg(\frac{6}{5} \bigg)[/tex]

and we are done!

66.4 in^2

Step-by-step explanation:

(L)= 6.3in

Area of base= (4)^2 =16 in^2

perimeter= 4×4 =16 in

L.A=1/2 ×p ×l

= 1/2×16×6.3=50.4 in^2

S.A=Base area + L.A

Step-by-step explanation:

i multiplied 12x16 and 192 then I multiplied 192x3 which gave me 576

Answer:

i believe the answer is 142.42 in²

Step-by-step explanation:

what i did was 'separate' the cone and cylinder-

so the volume of cylinder formula is-

v=πr²h

and the volume for a cone is-

v=πr²h/3

now let us fill in the formulas with the information that we have-

v=π*2²*10=125.66

v=π*2²*4=16.76

now let us add the sums together-

125.66+16.76=142.42 in²

good luck :)

Answer:

We accept H₀ sample does not give evidence to support that the proportion of Americans who solely use cell phone differs from 23 %

Step-by-step explanation:

A pew research finds  that  23 %  ( μ ) of Americans use only cell phone

Sample Information

sample size   n  = 200

x₁  =  51     then   p₁  = 51/200   p₁  =  0,255

and  q₁  =  1  - p ₁    q₁  =  1  - 0,255    q₁  =  0,745

Sample big enough for the approximation of the binomial distribution to the normal distribution

p₁*n  = 0,255 * 200 = 51  > 5   and   q₁*n    = 0,745* 200 =  149 > 5

Test hypothesis

Null hypothesis                       H₀              p₁  = μ = 0,23

Alternative hypothesis           Hₐ              p₁  ≠  0,23

Is a two tail test. We choose CI = 95 %  then significance level is                    α = 0,05 %

α = 0,05 as is a two tail test   α/2  = 0,025

from z-table  z(c) = 1,96

To calculate  z(s) = ( x  -  μ ) /√p₁*q₁/n  

  z(s) = ( 0,255 - 0,23 )/√0,255*0,745/200

z(s)  =  0,025 / 0,0308

z(s)  = 0,81

Comparing z(s)   and  z(c)

z(s) < z(c)      0,81 < 1,96

Then  z(s) is in the acceptance region: we accept H₀

Answer:

Step-by-step explanation:

Translate 2 units left and 4 units up: (x,y) -> (x-2 , y+4)

F (4,2) -> (4-2 , 2+4) -> (2 , 6)

Answer:

A

C

Step-by-step explanation:

recall the following rule:

[tex]n^x=y\\log_ny=x[/tex]

to solve the first one we have

[tex]40(10^x)=15\\10^x=\frac{15}{40}\\x=log(\frac{15}{40})[/tex]

This is equal to

[tex]\frac{log\frac{15}{40}}{log10}[/tex] or A

same deal for the second one

[tex]10^x=\frac{25}{50}\\x=log{\frac{25}{50}=\frac{log(\frac{25}{50})}{log10}[/tex] or C

[tex]Critical\ value=1.66039[/tex]

Step-by-step explanation:

From the question we are told that:

Sample size [tex]n=100[/tex]

Mean price of wheat [tex]\=x=2.136[/tex]

Standard error [tex]S_e=$0.013[/tex]

95% prediction interval

Generally the equation for 95% confidence is mathematically given by

[tex]\alpha=1-95\%[/tex]

[tex]\alpha=1-0.95[/tex]

[tex]\alpha=0.05[/tex]

Generally the degree of freedom [tex]d_f[/tex]  is mathematically given by

[tex]d_f=n-1[/tex]

[tex]d_f=100-1[/tex]

[tex]d_f=99[/tex]

Generally the critical [tex]t_{\alpha,df}[/tex] value is mathematically given by

[tex]t_{(0.05,99)}[/tex]

[tex]t_{(0.05,99)}=1.66039[/tex]

Therefore the critical associated with 95% predication interval is [tex]Critical\ value=1.66039[/tex]

Answer:

The percentage of people wearing basket ball shoe is,

= 32%

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

In a shoe store survey there are 200 customers.

Given in the table is that, people using basketball shoes, not using basket shoes and then there is also classification of people using running or non running shoes.

We have been asked what percentage of people have basketball shoes.

People having basket ball shoes = 0.18 × 200 + 0.28 ×200

                                                   = 64

Thus, The percentage of people wearing basket ball shoe is,

= 64/200 x 100

= 32 %

Hence, The percentage of people wearing basket ball shoe is,

= 32%
