<h3>The distance between Two co-ordinates =</h3>

$\sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2}}$

Here,

x1 = - 3

y1 = 5

x2 = - 6

y2 = - 4

Distance =

$= \sqrt{ { ( (- 6 ) - ( - 3))}^{2} + { ( - 4 - 5)}^{2} } \\ = \sqrt{ {( - 3)}^{2} + {( - 9)}^{2} } \\ = \sqrt{9 + 81} \\ = \sqrt{90}$

Hope this will help you....

Factor the expression. 35g^2 – 2gh – 24h^2

stiks02 [169]

Option C: $(7 g-6 h)(5 g+4 h)$ is the correct answer.

Explanation:

The given expression is $35 g^{2}-2 g h-24 h^{2}$

We need to determine the factor of the expression.

Now, let us break the given expression into two groups.

Hence, we get,

$35 g^{2}+28 g h-30 g h-24 h^{2}$

Simplifying, we get,

$\left(35 g^{2}+28 g h\right)+\left(-30 g h-24 h^{2}\right)$

Let us factor out 7g from the term $\left(35 g^{2}+28 g h\right)$

Hence, we have,

$7 g(5 g+4 h)+\left(-30 g h-24 h^{2}\right)$

Similarly, let us factor out -6h from the term $\left(-30 g h-24 h^{2}\right)$

Thus, we have,

$7 g(5 g+4 h)-6 h(5 g+4 h)$

Now, we shall factor out the term $5g+4h$ , we get,

$(7 g-6 h)(5 g+4 h)$

Thus, the factorization of the given expression is $(7 g-6 h)(5 g+4 h)$

Therefore, Option C is the correct answer.

A simple random sample of 49 8th graders at a large suburban middle school indicated that 82% of them are involved with some typ

melamori03 [73]

Answer:

0.142

Step-by-step explanation:

From the question, we identify the following parameters;

n = 49

p = 82% = 82/100 = 0.82

alpha, α = 1-0.99 = 0.01

Zα/2 = Z_0.005 = 2.575

margin of error = Zα/2 * √( p(1-p)/n)

Margin of error = 2.575 * √(0.82)(1-0.82)/49

Margin of error =0.1416005 which is approximately 0.142
