Two numbers have these properties:

almond37 [142]

Answer:

$12\ and\ 30$

Step-by-step explanation:

Given both numbers are greater than 6

Their HCF is 6

Their LCM is 60

The product of the HCF and LCM of two numbers is the same as the product of the numbers themselves.

Let us say those number are $a$ and $b$

$a\times b=6\times 60\\a\times b=360$

So, the product of those number is $360$

Let us factorize $360$

$360=1\times 2\times 2\times 3\times 5\times 6$

It is given that number should be greater than 6

The possible pairs of number are $(10,36)\ and\ (12,30)$

But only $(12,30)$ has LCM as 60.

So those numbers are $12\ and\ 30$

Answer:

$f(1) = {(1)}^{3} + 3 {(1)}^{2} - 9(1) + 5 \\ (x - 1) = 0 \rightarrow \: x = 1 \\\frac{{x}^{3 } + {3x}^{2} - 9x + 5}{x - 1} = {x}^{2} + 4x - 5 \\ (x + 5)(x - 1) = 0 \\ x = - 5 \: or \: x = 1 \\ \color{red}\boxed{x_{1} = 1} \\\color{yellow} \boxed {x_{2} = 1} \\ \color{green}\boxed{x_{3} = - 5}$

The answer would be C and F

Which of the following statements are true of the parabola shown?

Vesna [10]

<u>True statements are:</u>

It has a directrix of x = - 4.
It has a focus at (4, 0).

<u>Step-by-step explanation:</u>

We have the following statements to check on whether it's right or wrong:

<u>1. It has a directrix of x = -4:</u>

According to figure , parabola directrix is at -4 i.e. at x = -4 , Therefore this statement is true!

<u>2. It opens to the left:</u>

In figure, Parabola opens to right not left , Therefore this statement is wrong!

<u>3. It has a vertex at the origin:</u>

Vertex of Parabola is at what points not shown in figure. Therefore this statement cannot be confirmed as true.

<u>4. The axis of symmetry is the y-axis:</u>

Axis of symmetry for above parabola is x-axis as it cuts parabola into two equal halves , y-axis doesn't do this ! Therefore this statement is wrong!

<u>5. It has a focus at (4, 0):</u>

Parabola focus is at $F(4,0)$ on x-axis . And so, Therefore this statement is true!
