Answer:

C'(2, 1 )

Step-by-step explanation:

Assuming the dilatation is centred at the origin then multiply the coordinates of C by [tex]\frac{1}{3}[/tex] , that is

C(6, 3 ) → C'( [tex]\frac{1}{3}[/tex] (6), [tex]\frac{1}{3}[/tex] (3) ) → C'(2, 1 )

Answer:

14%

Step-by-step explanation:

Last year's score = 350

This year's score = 399

What was the percent of increase in Kenia's score

Percentage increase= (new score - old score) / old score × 100

= (399-350) / 350 × 100

= 49 / 350 × 100

= 0.14 × 100

= 14%

The percent of increase in Kenia's score is 14%

Answer:

Step-by-step explanation:

The sum of suplementary angles is allways 180°

so:

x  -   the other angle

3x  - three times the other angle

180°- x  - one angle

180° - x + 184° = 3x

   364° = 4x

     x = 91°

180°- x = 180° - 91° = 89°

Answer:

418 4/10

Step-by-step explanation:

To answer this we subtract 450 7/10 from 869 1/10.

We must borrow a '1' from 869 1/10:  868 11/10

Now subtract 450 7/10 from 868 11/10:

418 4/10 (CHANGE IN ELEVATION)

This reduces to 418 2/5.

Let's simplify step-by-step.

1/4 must be added to the given expression to make it a perfect-square trinomial.

The given expression is x²+x.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Add 1/4 to the given expression, we get

x²+x+1/4

= x²+x+(1/2)²

= (x+1/2)²

Verification:

x²+2.x.1/2+1/4

= x²+x+1/4

Therefore, 1/4 must be added to the given expression to make it a perfect-square trinomial.

Apply cross product property

[tex] \dashrightarrow{ \sf{ - 5 \times 9x = - 2}}[/tex]

Step-by-step explanation:

Step-by-step explanation:

A logarithm is a mathematical operation that determines how many times a certain number, called the base, is multiplied by itself to reach another number. ... Logarithms even describe how humans instinctively think about numbers.

Answer:

A logarithm tells what exponent (or power) is needed to make a certain number, so logarithms are the inverse (opposite) of exponentiation. Just as an exponential function has three parts, a logarithm has three parts. The three parts of a logarithm are a base, an argument (also called power) and an answer.

Answer:

100 meters

Step-by-step explanation:

Given the following :

Alex house = F

Alex school = H

Alex bus stop = G

FG = 2x meters

GH = 1000meters

FH = 1200 meters

Hence,

FH = FG + GH

1200 = (2x + 1000) meters

1200 = 2x + 1000

1200 - 1000 = 2x

200 = 2x

x = 100meters

Hence, x = 100 meters

Answer:

41

Step-by-step explanation:

Simplify the following:

(5 i + 4) (-5 i + 4)

Hint: | Multiply 4 + 5 i and 4 - 5 i together using FOIL.

(4 + 5 i) (4 - 5 i) = (4) (4) + (4) (-5 i) + (5 i) (4) + (5 i) (-5 i):

4×4 + 4 (-5 i) + 5 i×4 + 5 i (-5 i)

Hint: | Multiply 4 and 4 together.

4×4 = 16:

16 - 5×4 i + 5 i×4 + 5 i (-5)×i

Hint: | Multiply 4 and -5 together.

4 (-5) = -20:

16 + -20 i + 5 i×4 + 5 i (-5)×i

Hint: | Multiply 5 and 4 together.

5×4 = 20:

16 - 20 i + 20 i + 5 i (-5)×i

Hint: | Combine products of like terms.

5 i (-5)×i = 5 i^2 (-5):

16 - 20 i + 20 i + -5×5 i^2

Hint: | Evaluate i^2.

i^2 = -1:

16 - 20 i + 20 i - 5×5×-1

Hint: | Multiply 5 and -1 together.

5 (-1) = -5:

16 - 20 i + 20 i - 5-5

Hint: | Multiply -5 and -5 together.

-5 (-5) = 25:

16 - 20 i + 20 i + 25

Hint: | Evaluate 16 - 20 i + 20 i + 25.

16 - 20 i + 20 i + 25 = 41:
