What is the factorization of the polynomial below? 5x2 - 35x + 60

natita [175]

Answer:

$5(x-3)(x-4)$

Step-by-step explanation:

$5x^2-35x+60$

Start by factoring out a 5:

$5(x^2-7x+12)$

We need to find two integers that have a product of 12, and a sum of -7:

(-3)(-4)=12

-3-4=-7

We can split -7x into -3x and -4x

$5(x^2-3x-4x+12)$

Factor each half separately:

$5[x(x-3)-4(x-3)]$

Since x and -4 are both being multiplied by x-3, we can combine them:

$5(x-3)(x-4)$

What is the explicit rule for the geometric sequence? 600, 300, 150, 75, ...

pochemuha

Answer:

Step-by-step explanation:

Hello, this is a geometric sequence so we are looking for a multiplicative factor.

$a_0=600\\\\a_1=a_0 \cdot \boxed{\dfrac{1}{2}} = 300 = 600 \cdot \boxed{\dfrac{1}{2}}\\\\a_2=a_1 \cdot \boxed{\dfrac{1}{2}} = 150= 300 \cdot \boxed{\dfrac{1}{2}}\\\\a_3=a_2 \cdot \boxed{\dfrac{1}{2}} = 75 = 150 \cdot \boxed{\dfrac{1}{2}}$

So, the explicit formula is for n

$\boxed{a_n=a_0\cdot \left(\dfrac{1}{2}\right)^n=600\cdot \left(\dfrac{1}{2}\right)^n}}$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

A monkey is swinging from a tree. On the first swing, she passes through an arc whose length is 24 m 24 m24, start text, space,

Alchen [17]

Answer:

$24(\frac{1}{2})^{n-1}$

Step-by-step explanation:

Complete Question:

A monkey is swinging from a tree. On the first swing, she passes through an arc whose length is 24 m. With each swing, she travels along an arc that is half as long as the arc of the previous swing. Which expression gives the total length the monkey swings in her first n swings?

Solution:

First Swing:

24 m

Second Swing:

Half of first, so

24(1/2)

Third Swing:

Half of second, so:

24(1/2)(1/2)

Fourth Swing:

24(1/2)(1/2)(1/2)

So we see the general formula as:

$24(\frac{1}{2})^{n-1}$

Note: n -1 because (1/2) plays a role from second swing, which is n - 1

where n is the number of swings
