Find the distance between the points (-1,-2) and (5,2). Simplified radical form.
frozen [14]

Answer:

2\sqrt{13}

Step-by-step explanation:

Using the distance formula,

\sqrt{( x_{2}-x_{1} )^2+(y_{2} -y_{1})^2 }

We just need to plug in the numbers.

So \sqrt{(-1-5)^2+(-2-2)^2}

Then we simplify it to

\sqrt{(-6)^2+(-4)^2} , to \sqrt{36+16}

Finally, we get

\sqrt{52}, which is 2\sqrt{13} when simplified.

Which function can be used to model the graphed geometric sequence?
andreev551 [17]

Answer: The correct option is 1, i.e., f(x+1)=\frac{5}{6}f(x).

Explanation:

The geometric sequence is in the form of,

a,ar,ar^2,ar^3,....

Where, a is the first term of the sequence and r is the common ratio of the sequence.

It means the n_{th} term of the sequence is defined as,

a_n=ar^{n-1}

So the the (n+1)_{th} term of the sequence is defined as,

a_{n+1}=ar^n

a_{n+1}=r(ar^{n-1})

a_{n+1}=ra_n

It means the geometric sequence is in the form of,

f(x+1)=rf(x)

Where, r be any constant.

From the options only f(x+1)=\frac{5}{6}f(x) is in the form of f(x+1)=rf(x) with common ratio \frac{5}{6}.

Therefore, the function can be used to model the graphed geometric sequence is f(x+1)=\frac{5}{6}f(x) .

Evaluate 5(14 - 2³) +8 ÷ 2.? Plz help me, will mark you as brainliest A. 26 B. 34 C. 44 D. 56
dangina [55]

Answer:

\large \boxed{\sf B. \ 34}

Step-by-step explanation:

5(14 - 2^3 ) +8 \div 2

\sf Solve \ brackets.

2^3 =8

5(14 - 8 ) +8 \div 2

14-8=6

5(6 ) +8 \div 2

\sf Multiply \ and \ divide.

5(6)=30

8 \div 2 = 4

30 +4

\sf Add.

Can someone solve this for me?
pickupchik [31]

9514 1404 393

Answer:

  1. y = 0
  2. A all real numbers
  3. E y > 0
  4. infinity

Step-by-step explanation:

1. The horizontal asymptote is the y-value the function approaches, but does not reach. That value is y = 0. This equation is the equation of that asymptote.

__

2. The domain is the horizontal extent of the graph. It covers "all real numbers." (A)

__

3. The range is the vertical extent of the graph. As we said in part 1, the value y = 0 is never reached, so the vertical extent (range) is y > 0 (E).

__

4. The graph extends upward indefinitely as x extends to the left indefinitely. That is, y → infinity.

Please help me on this!​
scoray [572]

Answer:

235 cm^3

Step-by-step explanation:

I would start by "cutting" the shape into two parts; the top and the bottom

to find the area of these shapes you will need to use l*w*h

So substitute in the values

(5*5*4)+(9*3*5)=a

solve the parenthesis

100+135=a

add

235 cm^3
