Answer:

[B] [tex]y=log_3x[/tex]

Step-by-step explanation:

Given:

[tex]y=3^x[/tex]

Exchange the variables:

[tex]x=3^y[/tex]

Putting the variable y on the left side of the equation:

[tex]3^y=x[/tex]

Applying the logarithm properties:

[tex]y=log_3(x)[/tex]

Thus,

[tex]f^-^1=log_3(x)[/tex]

Hence, the answer is [B] [tex]y=log_3x[/tex]

The solution of the linear equation is x = 0.

An equation is a mathematical statement, which has an equal sign (=) between the algebraic expression.

Linear equations are the equations of degree 1.

The given linear equation is;

[tex]\rm 2(x-3)+ 9=3(x+ 1) +x[/tex]

The value of x is determined in the following steps given below.[tex]\rm 2(x-3)+9=3(x+1)+x\\\\2x-6+9=3x+3+x\\\\\ 2x+3=4x+3\\\\3-3=4x-2x\\\\0=2x\\\\x=0[/tex]

A parallelogram has an area of 37 square feet. If the height of the parallelogram is 4 feet, how many feet is the base?

The base of the given parallelogram is

Area of a parallelogram is defined as the product of its base and height respectively. Mathematically;

→ Area of parallelogram = base * height

By substituting the given values in the formula, we get the following results:

→ 37 = base * 4

→ base = 37/4

→ base = 9.25

Hence, the base of the given parallelogram is 9.25 feet.

Let's know something more about a parallelogram.

What is a parallelogram?

A parallelogram is a special type of quadrilateral whose opposite sides are parallel and hence its opposite angles are also parallel.

What is the formula of a parallelogram?

Let ‘B’ be the base and ‘H’ be the height of a parallelogram then its area is given by,

→ Area of parallelogram = B * H

What is unit of parallelogram?

The unit of a parallelogram is square units.

Answer:

A

Step-by-step explanation:

8-3=5

9/10 -4/10 =5/10

since 5/10 can be simplified to 1/2, it is A

the sum of all the angles in a triangle is 180°

65°+20°+x = 180°

85°+x = 180°

x = 95°

Answer:

divide it into a triangle and a segment then use Pythagoras thereom

The mean if the scores was misread at 94 but it was 69 is 87.5

Mean is also known as average. It is mathematically represented as:

Mean  = Sum of data/Sample space

Given the following parameters

Mean = 88

Sample size = 50

Substitute

88 = Sum/50

Sum = 88(50)

Sum = 4400

If one of the scores was misread at 94 but it was 69, hence;

Sum + (94-69) = 4400
Sum + 25 = 4400
Sum = 4400 - 25
Sum = 4331
New mean = 4375/50
New mean = 87.5

Hence the mean if the scores was misread at 94 but it was 69 is 87.5

Step-by-step explanation:

As the points A, B, C and D lie on a circle, So, ABCD is a cyclic quadrilateral...

As, Sum of opp. ∠s in a cyclic quadrilateral = 180°

∴ ∠ADC + ∠ABC = 180°

=> ∠ADC + 100° = 180° => ∠ADC = 80°

Now,

Sum, of all angles in a traingle = 180°

In ΔACD, ∠CAD + ∠ADC + ∠ACD = 180°

=> ∠CAD + 80° + 40° = 180°

=> ∠CAD = 180° - 80° - 40° = 60°

As CT is tangent to the circle at the point C and CD is a chord of the circle, So

∠DCT = ∠CAD........(∠s in alternate segments are equal,,So ∠CAD = 60°)

=> ∠DCT = 60°
