Answer:

y varies as √(x+5)

Step-by-step explanation:

y varies as √(x+5)

y= k√(x+5)

k is a constant connecting the two sides.

therefore

k=y/√(x+5)

k=4/√(-1+5)

k= 4/√4

k=4/2

k=2

Y when x=11

y=k√(x+5)

y=2√(11+5)

y=2√16

y=2*4

y=8

An arithmetic series a consists of consecutive integers that are multiples of 4 what is the sum of the first 9 terms of this seq

frez [133]

<h3>Answer: 144</h3><h3>Step-by-step explanation:</h3><h3 />

Since, the first 9 multiple of 4 starts from 0 are,

0, 4, 8, 12, 16, 20, ................

Which is an AP,

Having the first term, $a_1 = 0$

And, the successive difference, d = 4,

Since, the sum of the n term of an AP,

$S_n = \frac{n}{2}[2a + (n-1)d]$

Hence the sum of 9 term of the above AP,

$S_9 = \frac{9}{2}[2\times 0 + (9-1)\times 4]$

$S_9 = \frac{9}{2}(0 + 8\times 4)$

$S_9 = \frac{9}{2}(32)$

$S_9 = \frac{288}{2}=144$

Laura and Sean find the product of 2/3 x 4 using different methods.

choli [55]

Answer: So our equation is $\frac{2}{3} *4$

Laura does:

$\frac{2}{3}*4 = 2*\frac{1}{3} *4 = 2*\frac{4}{3} = \frac{4}{3} + \frac{4}{3} = \frac{8}{3}$

while Sean does:

$\frac{2}{3}*4 = \frac{2}{3} + \frac{2}{3} +\frac{2}{3} + \frac{2}{3} = \frac{8}{3}$

So sean sums four times the number 2/3, while Laura sums two times the number 4/3, this is because we are working with a multiplication, and the order of the factors does not alter the product.

The two are splitting the equations in different ways.
