Step-by-step explanation:

[tex]\sf \bf {\boxed {\mathbb {GIVEN:}}}[/tex]

[tex]a\:=\:2[/tex], [tex]b\:=\:-1[/tex] and [tex]c\:=\:-3[/tex]

7) [tex]3 {a}^{2} - b[/tex]

Plugging in the values of [tex]a[/tex] and [tex]b[/tex], we have

[tex] = 3( {2})^{2} - ( - 1)[/tex]

[tex] = 3(2 \times 2) + 1[/tex]

[tex] = 3 \times 4 + 1[/tex]

[tex] = 12 + 1[/tex]

[tex] = 13[/tex]

Hence, [tex]\boxed{ c. \:13 }[/tex] is the correct option.

8) [tex] {a}^{3} {b}^{3} - abc[/tex]

Plugging in the values of [tex]a[/tex] and [tex]b[/tex] and [tex]c[/tex], we have

[tex] = ({2})^{3} ( { - 1})^{3} - 2( - 1)( - 3)[/tex]

[tex] = (2 \times 2 \times 2)( - 1 \times - 1 \times - 1) - 2(3)[/tex]

[tex] = (8)( - 1) - 6[/tex]

[tex] = - 8 - 6[/tex]

[tex] = - 14[/tex]

Hence, [tex]\boxed{ d.\:-14 }[/tex] is the correct option.

Answer:

Iliana cannot construct a triangle because the sum of the two smaller sides will not be greater than the third side.

Answer:

O.6, 0.7, 3/4 (0.75)

Answer:

x=15 y=24

Step-by-step explanation:

This is because the rule is x goes up 3 y goes up 4

(9,12)->(x,20)

it skips one, so instead of adding 3 we add six

x=15

(15,20)->(18,y)

you follow the rule and 4.

Y=24

Answer:

Step-by-step explanation:

27 + x = 62

x = 62 - 27

x = 36

Answer:

f(-2) = -3

Step-by-step explanation:

When x = -2 we want the value of y

Step-by-step explanation:

According To The Question,

Now, for the population of bacteria in the culture after 14 hours is [tex]P_{t}[/tex] . We have Initial Population([tex]P_{i}[/tex])=41000 , d=14 & t=5 .

Put These Value in Above Formula, We get

[tex]P_{t} = 41000*(2)^{\frac{14}{5} }[/tex]

[tex]P_{t} = 41000*2^{2.8}[/tex]

[tex]P_{t} = 41000*(6.9644)[/tex]

Answer:

x-3=4

x=4+3

X=7

or

x-3=-4

x=-4+3

x=-1

-1 and 7

Step-by-step explanation:

Any equation within the | | notation is an absolute value, where the the value of the equation can only be positive.

So within the notation, we have two possibilities to the solution, a positive and negative value.

In other words, |4| = 4 and |-4| = 4

Hence, we only need to substitute x with an appropriate integer to satisfy the answer.

|x - 3| = 4

substitute x = 7

|7 - 3| = 4

|4| = 4

substitute x = -1

|-1 - 3| = 4

|-4| = 4

Therefore the solutions to x is x = 7 and x = -1.

Answer:

D

Step-by-step explanation:

Given y varies directly as x and z then the equation relating them is

y = kxz ← k is the constant of variation

To find k use the condition y = [tex]\frac{8}{3}[/tex] when x = 1 and z = 4 , then

[tex]\frac{8}{3}[/tex] = k × 1 × 4 = 4k ( divide both sides by 4 )

[tex]\frac{2}{3}[/tex] = k

y = [tex]\frac{2}{3}[/tex] xz ← equation of variation

When x = 6 and z = 3 , then

y = [tex]\frac{2}{3}[/tex] × 6 × 3 = [tex]\frac{2}{3}[/tex] × 18 = 2 × 6 = 12

Answer:

1 maps to 1

2 maps to 3

3 maps to 2

Step-by-step explanation:

the correctly assigned answer options describe everything.

there is not much else to say and explain.

these are all true statements due to the symmetry principle of a circle.

when 2 direct connections of two points on the circumference of a circle have the same length, then also their bent distances on the circumference of the circle are the same. and vice versa.

and yes, the perpendicular radius (or diameter) of the circle towards such a line cuts this line in half.

Answer:

PV= $73,201.14

Step-by-step explanation:

Giving the following information:

Future value (FV)= $85,000

Number of periods (n)= 20 months

Interest rate (i)= 0.03/4= 0.0075

To calculate the lump-sum required to reach the objective, we need to use the following formula:

PV= FV / (1 + i)^n

PV= 85,000 / (1.0075^20)

PV= $73,201.14

"Random Selection is a procedure of collecting a sample for a particular experiment in a truly random way."

30 members of a local gym were randomly selected to answer a survey.

The selected gym members were between the ages of 50 and 65.

Therefore, not all the members are between the ages of 50 and 65.

Answer:

240 dollars.

Step-by-step explanation:

I'd be assuming you mean the returns on interest rate after you put $6000 into the system, kind of like how you get returns after you deposit money at the bank. In that case:

[tex]6000 \cdot (1 + 4%) - 6000[/tex]

[tex]= 6240 - 6000[/tex]

[tex]= 240[/tex] dollars

Of course, you didn't say how frequently the interest rate would be compounded, so this result would be if the interest was compounded yearly.
