Answer: f(x)=56

Step-by-step explanation:

We are given the equation f(x)=6x²+2. Since we are asking for x=3, we can plug that into the equation and solve.

f(3)=6(3)²+2           [exponent]

f(3)=6(9)+2            [multiply]

f(3)=54+2               [add]

f(3)=56

Now, we know that f(x)=56 when x=3.

Answer:

x=4

Step-by-step explanation:

x/6 = 10/15

x/6 = 2/3

3x=12

Answer:

x=4

Step-by-step explanation:

To find this, you must first figure out the relationship between 10 and 15. Since 10 is 2/3 of 15, "x" must be 2/3 of 6.

To find "x", divide 6 by 3 to get 2, then 2 by 2 to get 2/3 of 6 (4). Thus meaning X = 4.

Answer:

The ratio of all the adjacent terms is the same and equal to

[tex]r=-4[/tex]

The next three terms after the last one will be:

Step-by-step explanation:

Given the sequence

-4, 16, -64, 256, …

Finding the common ratio

An arithmetic sequence has a constant ratio 'r' and is defined by  

[tex]a_n=a_1\cdot r^{n-1}[/tex]

computing the ratios of all the adjacent terms

[tex]\frac{16}{-4}=-4,\:\quad \frac{-64}{16}=-4,\:\quad \frac{256}{-64}=-4[/tex]

The ratio of all the adjacent terms is the same and equal to

[tex]r=-4[/tex]

Finding the next three terms

Given the sequence

-4, 16, -64, 256, …

here

[tex]a_1=-4[/tex]

[tex]r=-4[/tex]

substituting [tex]a_1=-4[/tex] and [tex]r=-4[/tex] in the nth term

[tex]a_n=a_1\cdot r^{n-1}[/tex]

[tex]a_n=-4\left(-4\right)^{n-1}[/tex]

substituting n = 5 to determine the 5th term

[tex]a_5=-4\left(-4\right)^{5-1}[/tex]

[tex]a_5=-4^4\cdot \:4[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

[tex]a_5=-4^{1+4}[/tex]

[tex]a_5=-4^5[/tex]

[tex]a_5=-1024[/tex]

substituting n = 6 to determine the 6th term

[tex]a_6=-4\left(-4\right)^{6-1}[/tex]

[tex]a_6=-4\left(-4^5\right)[/tex]

[tex]\mathrm{Apply\:rule}\:-\left(-a\right)=a[/tex]

[tex]a_6=4\cdot \:4^5[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

[tex]a_6=4^{1+5}[/tex]

[tex]a_6=4^6[/tex]

[tex]a_6=4096[/tex]

substituting n = 7 to determine the 6th term

[tex]a_7=-4\left(-4\right)^{7-1}[/tex]

[tex]a_7=-4^6\cdot \:4[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

[tex]a_7=-4^{1+6}[/tex]

[tex]a_7=-4^7[/tex]

[tex]a_7=-16384[/tex]

Therefore, the next three terms after the last one will be:

Answer:

$43.75

Step-by-step explanation:

To find how much the game would have been 20% off from 43.75, you would have needed the expression

43.75*0.8

So to go from 35 to 43.75, you need the expression

35/0.8.

This expression in simpler terms means What is 38, 80% of?

That is how we get 43.75.

35/0.8 = 43.75.

Answer:

46.75

Step-by-step explanation:

Answer:46.75

Answer:

it's density is 8 g /cm³

Step-by-step explanation:

Mass (m) = 96 g

Volume (v) = 12 cm³

Density (d) =?

We know density is defined as mass per unit volume so

d = m/v

= 96 / 12

= 8 g/cm³

Hope it will help :)

Note : if in the question it is said to write in sI system u have to write in kg/m³.

Step-by-step explanation:

<AOP + < BOP = 180°< being linear pair >

x + 30° + x - 30° = 180°

2x = 180°

x = 90°

Now

<AOP = x + 30° = 90° + 30° = 120°

<BOP = x - 30° = 90° - 30° = 60°

Hope it will help :)❤

The probability helps us to know the chances of an event occurring. The probability of Roxanne catching bass is 60%.

The probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

For the next four of the fishes to be bass, the numbers in the table must contain the digit 3 or 4 in it. Therefore, the cases where Roxanne catches bass are:

Also, it is mentioned that the total number of cases is 20 (Given in the table). Therefore, the probability of catching a bass can be written as,

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\\\Probability=\dfrac{\text{Number of cases where Roxanne catches fish}}{\text{Total number of catches}}\\\\\\Probability = \dfrac{12}{20} = 0.60\\\\Probability = 60\%[/tex]

Hence, the probability of Roxanne catching bass is 60%.

Answer:

$1.25 per hot dog

Step-by-step explanation:

Since we have given that

A deli sells 2 hot dogs for $2.50

i.e.

Cost of 2 hot dogs = $2.50

And we need to find the constant of proportionality of dollars per hot dog, for which we'll use unitary method.

So,

Cost of 1 hot dog is given by

2.50/2=$1.25

So, Cost of per hot dog is $1.25.

Answer:

im confused too so lets work together!

Step-by-step explanation:

(13 - 8 = 5.) so, rewrite the problem as 5 cubed divided by (5) x 2! Now, we figure out 5 cubed. 5 x 5 equals 25, x 5 equals 125. So, 125 divided by 5 would be 25. Now, 25 x 2 is 50.

The final answer would be 50!

Answer: 41 feet

Step-by-step explanation: The ladder, the building and the sidewalk creates a right triangle, with the 90° formed at the junction of sidewalk and building, so the length of the ladder is the triangle's hypotenuse.

To determine hypotenuse, use Pythagorean's theorem:

[tex]h^{2}=s^{2}_{1}+s^{2}_{2}[/tex]

[tex]h=\sqrt{40^{2}+9^{2}}[/tex]

[tex]h=\sqrt{1681}[/tex]

h = 41

For the ladder to reach the top of the building, it has to be 41 feet tall.
