please help to find a5 from the above question​

Given:

The logarithmic equation is:

[tex]\log x+\log (x-3)=1[/tex]

To find:

The value of x.

Solution:

Properties of logarithm used:

[tex]\log a+\log b=\log (ab)[/tex]

[tex]\log 10=1[/tex]

[tex]\log x[/tex] is defined for [tex]x>0[/tex].

We have,

[tex]\log x+\log (x-3)=1[/tex]

Using properties of logarithm, we get

[tex]\log [x(x-3)]=\log 10[/tex]

[tex]x^2-3x=10[/tex]

Splitting the middle term, we get

[tex]x^2-5x+2x-10=0[/tex]

[tex]x(x-5)+2(x-5)=0[/tex]

[tex](x-5)(x+2)=0[/tex]

[tex]x=5,-2[/tex]

In the given equation, we have a term [tex]\log x[/tex]. It means the value of x must be greater than 0 or positive. So, the only possible value of x is:

[tex]x=5[/tex]

Therefore, the value of x is 5.

Answer:

choice 3)

JK = 3.51

WK = 9.15

∠J = 69°

Step-by-step explanation:

sin 21° = JK/9.8

0.3584 = JK/9.8

cos 21° = WK/9.8

0.9336 = WK/9.8

WK = 9.15

∠J = 90° - 21° = 69°

Answer:

119.64m^3

Step-by-step explanation:

Given that

The height is 12.7 m

And the base with the circumference is 18.9 m

We need to find out the volume of the right circular cone

As for determining it first compute the radius

As we know that

Circumference = 2πr

18.9 = 2 × 3.14 × r

r = 3m

Now the volume is

= 1 ÷ 3πr^2h

= 1 ÷ 3 × 3.14 × 3^2 × 12.7

= 119.64m^3

Answer:

616 yd³

Step-by-step explanation:

Volume = base × height

The volume of the prism

= (7×8) ×11

= 616 yd³

Answer:

5.56 miles

Step-by-step explanation:

We are told from the above question:

Mei runs 66.72 miles in 6 weeks.

She runs 2 days each week

Therefore, the total number of days she runs in 6 weeks is calculated as:

1 week = 2 days

6 weeks = x

Cross Multiply

x = 6 weeks × 2 days/1 week = 12 days

The average distance she runs each day is calculated as:

12 days = 66.72 miles

1 day = x

Cross Multiply

12 days × x = 1 day × 66.72 miles

x = 1 day × 66.72 miles/12 days

x = 5.56 miles

The average distance she runs each day is 5.56 miles.

Answer:

1) 678.24

2)366.333.... repeating

3) 254.34

Step-by-step explanation:

1) 3.14 x 6² = 113.04 ---> 113.04 x 6 = 678.24

2) 3.14 x 5² = 78.5 ---> 78.5 x 14 = 1099 ---> 1099/3 = 366.333.... repeating

3) 3.14 x 9² = 254.34

Answer: here is the answer I had to do file hosting

Step-by-step explanation: https://www.wattpad.com/story/34339632-5sos-boyxboy-smut

To find a y term, find the absolute value of the x term (|x|).

Absolute value - the distance between 0 and a number. The absolute value of a number will always be equal to the positive form of the number (if it isn't already positive).

Some examples: The absolute value of 18 is 18. The absolute value of -10 is 10.

Find the absolute value of each x term to find y:

x ⇒ y

-2 ⇒ 2

-1 ⇒ 1

0 ⇒ 0 (the absolute value of 0 is always 0)

1 ⇒ 1

2 ⇒ 2

I hope this helps!

Answer:

Follow the same thing for the rest (plug the given in)

Step-by-step explanation:

1. y= 2x

x+y= -18

Plug 2x for y

x+2x= -18

3x=-18

x= -6

2.

x= 3y-1

x+2y=9

Plug 3y-1 for x

3y-1 +2y=9

5y= 10

y= 2

Step-by-step explanation:

inscribed angles made by same base should be equal

Answer:

so the three sides of same triangle have 36°,64° or 64°

we know the total sum of angles of triangle is 180 then

here to find x

so if we add all the 3 triangle and - (subtract) it with 180° = remaining side

now 36°+64°+64°= 164

now. x= 180-164= 16°

Answer:

43 + 24 = 67

38 + 29 = 67

This means that there equal making

D. 43 + 24 = 38 + 29

The correct answer.

Answer:

y = -5x + 4/3

Step-by-step explanation:

m is the slope and b is the y intercept. m= -5 so -5 is the slope and b= 4/3 so 4/3 is the y intercept.

Answer:

63

Step-by-step explanation:

the first one is 9x bigger then the second one

so 7x9 is 63

this one because x has to be bigger than 15.

The graph with inequality x>15 is (B)

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Given:

x>15

As, x is greater than 15.

So, the graph with x value labelled from the numbers greater than 15 which is represented by graph on right top corner.

Answer:

∠Q ≈ 42.969, ∠P ≈ 52.03, QR ≈ 15.036

Step-by-step explanation:

Law of sines:

13/sin Q = 19/sin 85°

=> sin Q = 13 × sin 85°/19

=> Q = sin^-1 (13 × sin 85°/19)

=> Q ≈ 42.969

∠P=> 180 - 85 - 42.969 ≈ 52.03

QR/sin 52.03° = 19/sin 85°

=> QR = sin 52.03° × 19/sin 85°

=> QR ≈ 15.036

If the scale factor is 2, then every coordinate point of the original triangle is multiplied by the scale factor 2.

Answer:

Its A

Step-by-step explanation:

V = (π)r^2(h)

R = 1/2 diameter

   = 24/2 = 12

   = 12

H = 12

V = (π)12^2(12)

V = (π)144(12)

V = (π)1728

V = 5428.67
