[tex]v=(3,4,5)-(1,2,1)=(2,2,4)[/tex]

[tex]w=(2,3,2)-(1,2,1)=(1,1,1)[/tex]

volume is given by [tex]V=u \cdot(v \times w)[/tex] [tex]v \times w=\left|\begin{array}{ccc}i & j & k \\ 2 & 2 & 4 \\ 1 & 1 & 1\end{array}\right|=(-2,2,0)[/tex]

three vectors are [tex]u=(4,4,6)-(3,3,3)=(1,1,3)[/tex]

Answer:

25

Step-by-step explanation:

Everytime, you add a value number 2 greater than the previous.

1+3=4

4+5=9

9+7=16

16+9=25

━━━━━━━☆☆━━━━━━━

▹ Answer

25

▹ Step-by-Step Explanation

1 + 3 = 4

4 + 5 = 9

9 + 7 = 16

16 + 9 = 25

The pattern is increasing the value of which is added by two each time:

3 + 2 = 5

5 + 2 = 7

7 + 9 = 16

9 + 16 = 25

Answer:

A. (40⋅1/1+3)+(40⋅2/2+3)

Step-by-step explanation:

Given that:

[tex]\sum \limits ^2 _{k=1} \dfrac{40 \ k }{k + 3}[/tex]

which can be expressed as:

=[tex]\dfrac{40\times 1 }{1 + 3} + \dfrac{40\times 2 }{2 + 3}[/tex]

=[tex]\dfrac{40 }{4} + \dfrac{80 }{5}[/tex]

= [tex]10+ 16[/tex]

= 26

∴

[tex]\sum \limits ^2 _{k=1} \dfrac{40 \ k }{k + 3} = 26[/tex]

Answer:

[tex]n = -5[/tex]

Step-by-step explanation:

Given

[tex]Digit = 0.000025[/tex]

Required

Rewrite using scientific notation, then find n

[tex]Digit = 0.000025[/tex]

Express as fraction

[tex]Digit =\frac{25}{1000000}[/tex]

This can be splitted to

[tex]Digit = 25 * 10^{-6}[/tex]

The first number must be between 1 and 10; hence, 25 can be expressed as 2..5 * 10

[tex]Digit = 2.5 * 10* 10^{-6}[/tex]

Apply law of indices

[tex]Digit = 2.5 * 10^{1-6}[/tex]

[tex]Digit = 2.5 * 10^{-5}[/tex]

Comparing n, the given options

[tex]n = -5[/tex]

Answer:

20

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

One fifth of 45 = 45/5=9

This means 9 dogs require small bowls.

If 9 require small, 20 require medium and the rest require large, then 45-9-20=16

16 dogs need large size bowl.

Step-by-step explanation:

so you take the numbers and put them in order from least to greatest. so it would be negative -1, 0, 1, 1, 2, 3, 4, 9, 17, 25, 33, 41 .

(a) The formula for the total time T, in minutes, needed to preheat the oven and bake a turkey weighing p pounds is T = 15 + 16p.

(b) The approximate time required to prepare a turkey weighing 14 pounds is 239 minutes.

We have,

(a)

To express the total time T, in minutes, needed to preheat the oven and then bake a turkey weighing p pounds, we can use the formula:

T = 15 + 16p

The first term, 15, represents the time needed to preheat the oven to 325 degrees (in minutes).

The second term, 16p, represents the recommended cooking time per pound for a turkey weighing p pounds (in minutes).

(b)

Using the formula T = 15 + 16p, we can find the approximate time required to prepare a turkey weighing 14 pounds:

T = 15 + 16 * 14

T = 15 + 224

T = 239

Therefore, the approximate time required to prepare a turkey weighing 14 pounds is 239 minutes.

Thus,

(a) The formula for the total time T, in minutes, needed to preheat the oven and bake a turkey weighing p pounds is T = 15 + 16p.

(b) The approximate time required to prepare a turkey weighing 14 pounds is 239 minutes.

Answer:100cm/1m

Step-by-step explanation:

Answer:

Domain: x ≥ 7

Range: y ≥ -1

Step-by-step explanation:

Domain is the set of x-values that can be inputted into function f(x).

Range is the set of y-values that can be outputted from function f(x).

We know that we can't take a square root of a negative and get a real number. The closest we can get is the square root of zero, no less.

What x-value renders the square root 0? x = 7 does, and we can't go less than that or we will get imaginary numbers. Therefore, the domain is x ≥ 7.

To find the range, we simply solve the rest of the function when x = 7, as we cannot go any lower.

y = 0 - 1

y = -1

Therefore, our range has to be y ≥ -1 because that would be the lowest y-value outputted from the lowest x-value.

Step-by-step explanation:

A graph is formed using the height of students in Diego's math class.

It is provided that he arranges the students from shortest to tallest and measures the height in inches of each student in the class.

A distribution is known as to be skewed to the right, or positively skewed, when maximum of the data are collected on the left of the distribution and the graph has a longer tail towards the right.

For a positively skewed data: Mean > Median

A distribution is said to be skewed to the left, or negatively skewed, if maximum of the data are collected on the right of the distribution and the graph has a longer tail towards the left.

For a negatively skewed data: Mean < Median

A distribution is said to be symmetric, if maximum of the data are collected in the middle of the distribution and the graph has equal proportion of tails on both sides.

For a symmetric data: Mean = Median

Cross Multiply

[tex]9x = 166.25[/tex]

Divide both sides of the equation by 9

[tex] \frac{9x}{9} = \frac{166.25}{9} [/tex]

[tex]x = 18.472[/tex]

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{18.472 \: miles}}}}}[/tex]

Step-by-step explanation:

Distance travelled = 166.25 miles

gallons of gas used = 9 gallons

To find : 1 gallons of gas = ? miles

In unitary method, we have to obtain unit quantity. So, to find the distance travelled using 1 gallons of gas, 166.25 is divided by 9

Answer:

65%

Step-by-step explanation:

The formula for the grade of the ramp = Rise of the ramp/ horizontal distance of the ramp

Rise of the ramp = 52 feet

Horizontal distance = 80 feet

Grade of the ramp = 52 feet/80 feet

= 0.65

The grade of the ramp is 0.65

Rounding up to the nearest whole percent

Grade of the ramp = 0.65 × 100

= 65%

Therefore, the grade of the ramp to the nearest whole percent = 65%

Answer:

0.06546.

Step-by-step explanation:

Total number of tickets = 715

Good raffle tickets  (Prize) = 4

Number of tickets bought = 12

[tex]\text{Probability of winning}=\dfrac{\text{Number of tickets bought}}{\text{Total raffle tickets}}[/tex]

[tex]\text{Probability of winning}=\dfrac{12}{715}[/tex]

[tex]\text{Probability of not winning}=1-\dfrac{12}{715}=\dfrac{703}{715}[/tex]

Let x be event of the number of winning prizes.

Probability that you will win at least 1 of the raffles is

[tex]P(x\geq 1)=1-P(x=0)[/tex]

[tex]P(x\geq 1)=1-^{4}C_0\left(\dfrac{12}{715}\right)^0\left(\dfrac{703}{715}\right)^{4-0}[/tex]

[tex]P(x\geq 1)=1-\left(\dfrac{703}{715}\right)^{4}[/tex]

[tex]P(x\geq 1)=1-0.93454[/tex]

[tex]P(x\geq 1)=0.06546[/tex]

Therefore, the required probability is 0.06546.

Answer:

155

Step-by-step explanation:

∠QOR= 25

∠POQ = x

here sum of both angles is 180 ( by linear pair)

therefore,

∠QOR + ∠POQ =180

25 + x = 180

x=180-25

x=155

hence, ∠POQ= 155

The total number of seats in the auditorium are 2225.

Given is that an auditorium has 50 rows of seats. The first row has 20 seats, the second row has 21 seats, the third row has 22 seats.

We can write the sequence as -

20, 21, 22, 23, 24, .......,

It is a arithmetic sequence. We can write the total number of seats in the auditorium as the sum of the terms of the sequence. We can write -

S{n} = (50/2)(2 x 20 + 49 x 1)

S{n} = 25(40 + 49)

S{n} = 25 x 89

S{n} = 2225

Therefore, the total number of seats in the auditorium are 2225.
