Answer:

He showed that f(n) ÷ f(n - 1) was a constant ratio.

Given that Jake has proved that a function f(x) is a geometric sequence.

GEOMETRIC SEQUENCE: A geometric sequence is a sequence of numbers where each term is found by multiplying the preceding term by a constant called the common ratio, r.

So, in Jame's proof, he showed that each term is multiplied by a constant to get the next term.

That is, if 'c' is the constant that was used in the proof, then we must have

This implies that

Therefore, he showed that f(n) ÷ f(n - 1) was a constant ratio.

4 × (3 + 7) = (4 ×[]) + (4 ×[])

Naily [24]

Answer:

4 × (3 + 7) = (4 ×7) + (4 × 3)

Step-by-step explanation:

If you go by the order of PEMDAS you would do the parentheses first. 3 + 7 =10. 10 × 4 = 40. Then you would just use the distributive property and do (4× 7) + (4 × 3)

4 × 7 = 28 and 4 × 3 = 12 28 +12 =40

In the figure below, UX and UV are tangent to the circle centered at 0. The segment XV passes through the center of the

Karo-lina-s [1.5K]

Answer:

2.5

Step-by-step explanation:

The computation of the XW is shown below

As triangle UVX is a right angle

VU^2 = XU^2 - VX^2

VU^2 = 15.7^2 - 8.5^2

VU^2 = 246.49 - 72.25

VU^2 = 174.24

VU = 13.2

As VU = WX because of same point tangent

NOw XW is

= UX - UW

= 15.7 - 13.2

= 2.5

Area for a kite<br> I don’t know how to find the area pls help

dusya [7]

Answer:

63.966

Step-by-step explanation:

Area of a kite is

$\frac{pq}{2}$

where p and q are the diagonals.

The horinzontial diagonal is 8.

We need to find the vertical diagonal length.

The top triangle diagonal measure is

${4}^{2} + {x}^{2} = {7}^{2}$

$16 + {x}^{2} = 49$

${x}^{2} = 33$

$x = \sqrt{33}$

The bottom triangle diagonal measure is

${4}^{2} + {x}^{2} = {11}^{2}$

$1 6 + {x}^{2} = 121$

${x}^{2} = 105$

$x = \sqrt{105}$

Add the two diagonals.

$\sqrt{105} + \sqrt{33}$

Substitute this in for the formula

$\frac{8 \times ( \sqrt{105} + \sqrt{33} }{2}$

Which simplified gu

Answer:

18.7 m/h

Step-by-step explanation:

I believe that is the correct answer because it shows the answer is going to be m/h (meter/hour) so then you would just divide the meters over the hours.

768.57 / 41.1 = 18.7 m/h
