Answer: x = 12

<u>Step-by-step explanation:</u>

a) Linear Pair: 110° + ∠a = 180° --> ∠a = 70°

b) congruent sides implies congruent angles --> ∠b = 70°

c) Triangle Sum Theorem: ∠a + ∠b + ∠c = 180

70° + 70° + ∠c = 180°

∠c = 40°

d) Complimentary Angles: ∠c + ∠d = 90°

40° + ∠d = 90°

∠d = 50°

∠2) Linear Pair: ∠d + ∠2 = 180°

50° + ∠2 = 180°

∠2 = 130°

x) m∠2 = 130°

10x + 10 = 130°

10x = 120

x = 12

Write an equation for a polynomial with all the following features: The Degree is 5. The graph of the Polynomial crosses the ver

dimulka [17.4K]

Answer: f(x) = a*x^5 + b*x^3 + c*x^2 + 12.

Step-by-step explanation:

The degree is 5, so we will have a term like:

a*x^5

it crosses the vertical axis at y = 12, then we will have a constant term equal to 12.

The polynomial has 4 terms, and we already defined two, so we can invent two more, such that the exponent must be between 1 and 4

This polynomial can be something like:

f(x) = a*x^5 + b*x^3 + c*x^2 + 12.

where a, b and c are real numbers.

Has 4 terms, f(0) = 12, then it intersects the y-axis at y = 12, and the maximum exponent is 5, then the degree of f(x) is 5.

Which experimental design compares two groups (randomly formed) on the same task, such as movement speed

anygoal [31]

Between-group design compares two groups (randomly formed) on the same task, such as movement speed.

Given things that there are two groups that are randomly formed for the same task.

A between-group design in experimental design is an experiment in which two or more groups of individuals are assessed simultaneously by separate testing factors. This design is typically used instead of, or in conjunction with, the within-subject design, which applies identical modifications of circumstances to each participant in order to monitor the reactions.

Simply: 200+(20-4)-2×3

alexandr1967 [171]

Answer:

The answer is 210

Step-by-step explanation:

200+(20-4)-2x3

first you'd do 20-4= 16

then you'd do 2x3=6

next you'd 16-6=10

finally 200+10=210

Northern Bank has two types of account. Both accounts pay compound interest. Cash savings account Interest 2.5% per annum Shares

musickatia [10]

Answer: Ben will have the most interest.

Step-by-step explanation:

Ali after 3 years.

To use compound interest, the formula is:

= Investment * ( 1 + rate) ^ no. of periods

= 2,000 * ( 1 + 2.5%)³

= £‭2,153.78

Interest = Amount after 3 years - investment

= 2,153.78 - 2,000

= £153.78

Ben after 3 years.

= 1,600 * (1 + 3.5%)³

= £1,773.95

Interest = 1,773.93 - 1,600

= £173.93
