Answer:

Scientific notation of 0.00000033 is $3.3\times10^{-7}$

Step-by-step explanation:

Given number,

0.00000033

We need to write it in scientific notation.

We know that in scientific notation number only has ones place before decimal which is multiplied with exponent of 10

Consider,

0.00000033

$=\frac{3.3}{10000000}=\frac{3.3}{10^7}=3.3\times10^{-7}$

Therefore, Scientific notation of 0.00000033 is $3.3\times10^{-7}$

Write the sum as a product of two factors 25g+10+5

agasfer [191]

Answer:

$5\times(5g+2f+1)$

Step-by-step explanation:

$25g+10f+5$

Writing each term in its factors:

$(5\times5)g+(5\times2)f+5$

We find out that 5 is the GCF of all the terms

Factoring out 5 from the given expression.

$5\times(5g+2f+1)$

Factors: 5 and $(5g+2f+1)$

Thus:

$25g+10f+5 = 5\times(5g+2f+1)$

If StartFraction pi Over 2 EndFraction less than t less than pi , which of the following is true?

oksian1 [2.3K]

Answer:

b. cosine t less than 0 and cotangent t greater than 0

Step-by-step explanation:

We have the following relation

$\frac{\pi }{2} < t$

if we apply the cosine function in the relation we get:

$cos\frac{\pi }{2}$

$-1$

the cosine of t is between 0 and -1 then (cosine t less than 0)

If we now apply cotangent function in the relation:

$cotan\frac{\pi }{2}$

$0$

This means that cotang is greater than 0, therefore the correct answer is b. cosine t less than 0 and cotangent t greater than 0

I need help please explain how to do these two question as I did the rest of them. I just don't understand these.

Alexxandr [17]

Answer:

7. (4x +10)/(x^3 +3x^2 -16x -48)

9. -320/93

Step-by-step explanation:

7. As with adding any fractions, first you find a common denominator. When the fractions are rational expressions, it often helps to factor the denominators.

6/(x^2 -16) -2/(x^2 -x -12) = 6/((x -4)(x +4)) -2/((x -4)(x +3))

= (6(x +3) -2(x +4))/((x -4)(x +3)(x +4)) . . . . . using a common denominator

= (6x +18 -2x -8)/((x -4)(x +3)(x +4))

= (4x +10)/((x^2 -16)(x +3))

= (4x +10)/(x^3 +3x^2 -16x -48)

_____

9. First you simplify the denominator:

2/25 -5/16 = (2·16 -5·25)/(25·16) = -93/400

Then you perform the division. This can be done by multiplying by the inverse of the denominator.

(4/5)/(2/5 -5/16) = (4/5)·(-400/93) = -320/93
