Answer:

D = -1, -1, 2, 5

R = 0, 2, 3, 7

✅It is NOT A FUNCTION

Step-by-step explanation:

D (Domain) = input values (x-values)

D = -1, -1, 2, 5

R (Range) = output values

R = 0, 2, 3, 7

✅It is not a function because an x-value, -1, has two different y-values, 7 and 2, assigned to it.

Answer:

7+4i+9+5i-2-5i

7+4i+9-2

4i+7+9-2

4i+14

Answer: 14 + 4i

Step-by-step explanation:

(7 + 4i) + (9 + 5i) - (2 + 5i)

Group the real part and the imaginary part of the complex number

(a + bi) ± (c + di) = (a ± c) + (b ± d)i

(7 + 9 - 2) + (4 + 5 - 5)i

7+9-2=14 and 4+5-5=4

Therefore, (7+4i)+(9+5i)-(2+5i) is equal to 14 + 4i

The formula calculates the cyclist's separation from the starting point, x, and will be x² = 5² + 3² - 2(5)(3)cos(140°).

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given information in the question,

From the cos law ;

x² = a² + b² - 2ab cos θ

The values obtained will be,

a =5

b =3

θ = 180° +70° -30°

θ = 180°- 40°

θ = 140°

Substitute the given values in the equation,

x² = a² + b² - 2ab cos θ

x² = 5² + 3² - 2(5) (3) cos(140°)

Answer:

60,000

Step-by-step explanation:

Let us represent:

Costs price = x

Selling price = x - 25%x

x - 0.25x

= 0.75x

If it been sold for Rs 21,000 more then the profit would have been

10%. = x + 10% = 1.1x

1.1x =0.75x + 21000

Collect like terms

1.1x - 0.75x = 21000

0.35x =21000

x = 21000/ 0.35

x = 60000

The cost price of the item = 60,000

Answer:

Step-by-step explanation:

-x² + 70x - 600

If we multiply all by -1, we have

x² - 70x + 600

If we factorise this, we have

x² - 10x - 60x + 600

x(x - 10) - 60(x - 10)

(x - 10) (x - 60)

x = 10

x = 60

If the company sells 10, or 60 items, their profit is 0

c) 2x^2y + 2xy^2

Explanation:

(x^2 y-3y^2+5xy^2)- (-x^2y+3xy^2-3y^2)

(x^2 y+5xy^2 -3y^2)- (-x^2y+3xy^2-3y^2)

x^2 y +5xy^2 -3y^2 + x^2y -3xy^2 + 3y^2

2x^2y + 2xy^2

The option C) 2x²y + 2xy² is equivalent to the given expression (x²y - 3y² + 5xy²) - (-x²y + 3xy² - 3y²).

Mathematically, an expression is an admixture of numbers, variables, operations, and functions that are conjoined according to peculiar rules to depict a mathematical calculation or association. It can be supposed to as a mathematical idiom or formula.

By combining numbers, variables, operators, and functions, mathematical expressions can define a broad lea of calculations and associations.

The given expression is (x²y - 3y² + 5xy²) - (-x²y + 3xy² - 3y²).

(x²y - 3y² + 5xy²) - (-x²y + 3xy² - 3y²)

= x²y - 3y² + 5xy² + x²y - 3xy² + 3y²

= 2x²y + 2xy².

Hence, option C) is correct in that 2x²y + 2xy² is equivalent to the given expression.

Answer:

70 degrees

Step-by-step explanation:

Angles 130 degrees and TUV are supplementary angles.  Thus, the latter is (180 - 120), or 60, degrees.  Now the sum of all three interior angles of this triangle must be 180 degrees:  (60 + 50 + >TUV) = 180, so >TUV is 70 degrees (answer C).

Answer:

Surface area of triangular prism = 528

Step-by-step explanation:

Surface area of triangular prism = (Base x Height) + 2 (length x side) + (length x base)

SA = bh + 2Ls + Lb

Putting given values : b = Y = 5 , h = 9 , s = x = 9 , L = z = 21

(5 x 9) + (2 x 21 x 9) + (21 x 5)

= 45 + 378 + 105

Answer: Yes he does.

Step-by-step explanation:

The shirt costs £9.60 and is on discount by 1/3.

1/3 = 0.3333

The discounted price is therefore:

= 9.60 * (1 - 0.3333)

= £6.43

The price of two shirts is:

= 6.43 + 6.43

= £12.86

Billy has £13 which is above the price of two so he will be able to buy 2 shirts.
