what is the diameter of the following circle? (x-6)^2 + (y-7)^2 =25

So

an=an+b

14=4a+b and a=-8

14=-32+b

b= 46

an=-8n+46

Answer with Step-by-step explanation:

[tex]a_{4}=14[/tex]

Each term of the sequence is 8 less than the previous term

⇒ [tex]a_{3}=14+8=22[/tex]

⇒ [tex]a_{2}=22+8=30[/tex]

⇒ [tex]a_{1}=30+8=38[/tex]

In general [tex]a_{n}=a_{n-1}-8,a_{1}=38[/tex]

Hence, recursive formula representing the situation is:

[tex]a_{n}=a_{n-1}-8,a_{1}=38[/tex]

[tex] - {x}^{2} + 10x + 5 \\ = - {x}^{2} + 10x - 25 + 5 + 25 \\ = - ( {x}^{2} - 10x + 25) + 30 \\ = \underbrace{ - {(x - 5)}^{2}}_{\leqslant 0} + 30 \\ \Rightarrow - {(x - 5)}^{2} + 30 \leqslant 30 \\ \Rightarrow Maximum \: value \: is \: 30 \: when \: x = 5[/tex]

6 feet 4 inches

Step-by-step explanation:

Step-by-step explanation:

3 FEET 2 INCHES These are not the same! Do not multiply

Each foot is 12 inches. So 3 times 12 (3 feet) is 36, add the extra 2 inches for 38 inches.

38 plus 32 equals 70 total inches. NOw we put it back into feet.

70 divided by 12 is 5, remainder 10.

So Valerie's sister will be 5 feet 10 inches (G)

Final answer:

The perimeter of triangle DEF is 24 centimeters.

Explanation:

The perimeter of a triangle is the sum of the lengths of its three sides. In this case, triangle ABC is congruent to triangle DEF, and each side of triangle ABC is 1.5 times longer than the corresponding side of triangle DEF. Let's assume the lengths of the corresponding sides of triangle DEF are x, y, and z. Therefore, the lengths of the corresponding sides of triangle ABC are 1.5x, 1.5y, and 1.5z.

Since the perimeter of triangle ABC is 36 centimeters, we can set up the equation as follows: 1.5x + 1.5y + 1.5z = 36. Simplifying the equation, we get x + y + z = 24. This means the perimeter of triangle DEF is 24 centimeters.

Since distance is equal to rate times time:

Let x= the time traveled at 3 km/h

Let y= the time traveled at 4 km/h

We can say that

3x+4y=52

Or that three (kilometers) times the time traveled at 3 kilometers an hour plus 4 (kilometers) times the time traveled at 4 kilometers an hour is equal to 52; the total distance traveled.

Likewise, we can see that:

x+y=15

Because x, the number of hours traveled at 3 km/h added to y, the time traveled at 4 km/h is equal to 15; the total time traveled.

Now, I'll solve by substitution.

x=-y+15

Substitute that into the other equation.

3(-y+15) + 4y = 52

Distribute

-3y + 45 + 4y = 52

Combine like terms

y + 45 = 52

Minus 45 from both sides

y = 7

So Fredrick traveled at 4 km/h for 7 hours.

Now, to find the other value, substitute the value of y into one of the original equations.

x + 7 = 15

Minus 7

x = 8

So

Time traveled at 4 km/h = 7 hours

Time traveled at 3 km/h = 8 hoursSince distance is equal to rate times time:

Let x= the time traveled at 3 km/h

Let y= the time traveled at 4 km/h

We can say that

3x+4y=52

Or that three (kilometers) times the time traveled at 3 kilometers an hour plus 4 (kilometers) times the time traveled at 4 kilometers an hour is equal to 52; the total distance traveled.

Likewise, we can see that:

x+y=15

Because x, the number of hours traveled at 3 km/h added to y, the time traveled at 4 km/h is equal to 15; the total time traveled.

Now, I'll solve by substitution.

x=-y+15

Substitute that into the other equation.

3(-y+15) + 4y = 52

Distribute

-3y + 45 + 4y = 52

Combine like terms

y + 45 = 52

Minus 45 from both sides

y = 7

So Fredrick traveled at 4 km/h for 7 hours.

Now, to find the other value, substitute the value of y into one of the original equations.

x + 7 = 15

Minus 7

x = 8

So

Time traveled at 4 km/h = 7 hours

Time traveled at 3 km/h = 8 hours

Answer:

1) 1.8 round to tenths

Step-by-step explanation:

To find the mean absolute deviation we follow these steps:

1) 4,5,10,8,4,8,7,6

step 1

4+5+10+8+4+8+7+6 / 8 = 6.5

Mean (μ): 6.5

step 2

|4-6.5| + |5-6.5| + |10-6.5| + |8-6.5| + |4-6.5| + |8-6.5| +|7-6.5| + |6-6.5|  = 14

step 3

14 / 8 = 1.75  

Repeat these steps for other parts.

Answer:

8x³ - 5x² + 8x

Step-by-step explanation:

to solve the perimeter, you need to add all sides of the triangle together.

8x² + x³ + 2x² + 7x³ - 3x² + 6x

now, code all the similar variables:

8x² + x³ + 2x + 7x³ - 3x² + 6x

8x² - 3x² = 5x²

x³ + 7x³ = 8x³

2x + 6x = 8x

so, put them all together:

5x² + 8x³ + 8x

but remember that the larger exponent comes first(just a rule)

so, it is : 8x³ - 5x² + 8x

[tex]3.1^4=(3.1)(3.1)(3.1)(3.1)\to\boxed{A}\\\\3.1^4=[(3.1)(3.1)](3.1)(3.1)=(9.61)(3.1)(3.1)\to\boxed{B}\\\\3.1^4=[(3.1)(3.1)][(3.1)(3.1)]=(9.61)(9.61)\to\boxed{D}[/tex]

Equivalent expressions to 3.1⁴ involve raising 3.1 to the power of 4. This means 3.1 is multiplied by itself four times, not three times (which would be cubing). The equivalent expression would result from multiplying 3.1 by itself four times.

The equivalent expressions to 3.1⁴ involve the operation of raising a number to a power. In this case following the number 3.1, the exponent of 4 means that 3.1 is being multiplied by itself four times, and it is not the same as cubing. The cubing of exponentials refers to the process of raising a number to the power of three or multiplying the number by itself three times. The commutative, associative, and distributive laws can be applied to simplify and rewrite exponential expressions. Therefore, to find an equivalent expression for 3.1⁴, you would need to multiply 3.1 by itself four times.

Step-by-step explanation:

I just did the problem.

Simplifying

5(7x + -3) = 230

Reorder the terms:

5(-3 + 7x) = 230

(-3 * 5 + 7x * 5) = 230

(-15 + 35x) = 230

Solving

-15 + 35x = 230

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '15' to each side of the equation.

-15 + 15 + 35x = 230 + 15

Combine like terms: -15 + 15 = 0

0 + 35x = 230 + 15

35x = 230 + 15

Combine like terms: 230 + 15 = 245

35x = 245

Divide each side by '35'.

x = 7

Simplifying

x = 7

Answer:

are perpendicular

Yes, it is perpendicular

Parallel is when you have two lines that do not intersect

A ray is a line that has one definite starting point and no obvious end point. (Stars with a point and "ends" with an arrow, meaning that it goes on "forever")

A line is just one specific line

When you have perpendicular, that is when two lines cross each other forming a right angle as you may now know
