It is a Part A and Part B Question

Note: please add the answer next to what part it's from so I can know which part was answered

Answers

Answer 1

Step-by-step explanation:

oh, come on ! one is finding the inequality itself, the other is solving it. you don't know the difference of that ?

if so, please let me know, what you don't understand of the following explanations, so that I can add whatever is necessary.

you know, what an equality (ahem, equation) is ?

both, equations and inequalities are like a balancing scale with usual different things on the two pans left and right.

an equation is when both sides are in balance. their weight is equal.

an inequality is, when one side is heavier than the other.

and you know, what a variable is ? it is a kind of placeholder for actual values. it is like keeping some space open on the scale pan with a list of conditions for what kind of things you can put in that open space, so that the status of the scale stays unchanged.

twenty less than a number is at least 15

looks mathematically

x - 20 >= 15 (larger or equal = "at least")

x - 20 >= 15

x >= 35

so, this is true for

{x € R | x >= 35}

{x € R | x = 35 or x > 35}

so, this is true for all real values of x that are at least 35.

Answers

Answer: B

Step-by-step explanation:

In the following function defined by an equation in the form y = a x squared + b x + c, identify the values of a, b, and c.
y = 5 x squared + 2 x minus 1
a.

a = negative 1, b = 2, c = 5
b.

a = negative 2, b = 5, c = 1
c.

a = 1, b = 5, c = 2
d.

a = 5, b = 2, c = negative 1

The correct answer is option D which is a = 5, b = 2, c = - 1.

What is a quadratic equation?

It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Given that:-

y = 5x² + 2x - 1

The general form of the equation is given as:-

Y = ax² + bx + c

We have a quadratic equation:-

y = 5x² + 2x - 1

By comparing the equation with the general form the value of a, b and c is calculated:-

a = 5

b = 2

c = -1

Therefore the correct answer is option D which is a = 5, b = 2, c = - 1.

What percent of 6 is 9?

Answers

Answer:

150%

Step-by-step explanation:

half of 6 is three, and 9 has a value of 3 more than 6. meaning that 9/6 = 150%

Answer: [tex]150[/tex]% [tex]([/tex][tex]0.54[/tex][tex])[/tex]

Step-by-step explanation:

For fraction: divide 6 by 100 and remove the % sign.

{[tex]6[/tex]}% [tex]=\frac{6}{100}[/tex]

For decimal: move the decimal point 2 places to the left and remove the % sign.

{[tex]6[/tex]}% [tex]=0.06[/tex]

[tex]100[/tex]% [tex]=9[/tex]

[tex]\frac{6}{100}[/tex] × [tex]9=0.06[/tex] × [tex]9=0.54[/tex]

[tex]6[/tex]% [tex]of~9~is~0.54[/tex]

Write a rule for the input/output table

Answers

The table is a linear function, and the rule for the input/output table is f(x) = 1 + 3x

How to determine the rule?

From the table, we can see that:

The output of the table is 1 more than 3 times the input

If the input is x, then the output y is:

y = 1 +3 * x

Evaluate

y = 1 + 3x

Hence, the rule for the input/output table is f(x) = 1 + 3x

The coordinating sine value for this angle of rotation will be 4.189.

How to calculate the angle?

From the complete information, in the unit circle, there's a point with -1/2 and the x value is 240°.

In this case, the coordinating sine value for this angle of rotation will be:

= (240 × π)/180

= (240 × 3.142) / 180

= 4.189

an = 2(an − 1 + 4) and a1 = 5 (the n and n-1 is suppose to be a subscript, I just can't figure out how to make it like that)

Answers

Answer:

5, 18, 44, 96, 200

Step-by-step explanation:

Given

aₙ = 2(aₙ₋₁ + 4)a₁ = 5

First term : 5

Second term : a₂ = 2(a₁ + 4)

a₂ = 2(5 + 4) = 2(9) = 18

Third term : a₃ = 2(a₂ + 4) = 2(18 + 4) = 2(22) = 44

Fourth term : a₄ = 2(a₃ + 4) = 2(44 + 4) = 2(48) = 96

Fifth term : a₅ = 2(a₄ + 4) = 2(96 + 4) = 2(100) = 200

Hence, the first 5 terms of the sequence are :

5, 18, 44, 96, 200

Answer:

5, 18, 44, 96, 200

Step-by-step explanation:

[tex]\textsf{Given sequence}: \quad a_n=2(a_{n-1}+4)[/tex]

[tex]\textsf{Given first term}: \quad a_1=5[/tex]

[tex]\implies a_1=5[/tex]
