Answer:

We can convert a mixed number (or mixed fraction) to a decimal. Strategies to convert mixed fractions to decimals: Change the mixed fraction to an improper fraction and then divide. Convert the fractional part only and then add it to the whole number.

Answer:

Yes

Step-by-step explanation:

Any mixed number that you have, is really the whole number and a set amount of fractions behind it.

If you have 3 $\frac{6}{9}$ , then you can change that to 3.6666.... If you have 1 $\frac{1}{2}$ , then you can change that to 1.5.

Hope that this helps!

The position of an object along a vertical line is given by s(t) = −t3 + 3t2 + 7t + 4, where s is measured in feet and t is meas

saw5 [17]

Answer:

The maximum velocity of the object in the time interval [0, 4] is 10 ft/s.

Step-by-step explanation:

Given : The position of an object along a vertical line is given by $s(t) = -t^3+3t^2+7t +4$ , where s is measured in feet and t is measured in seconds.

To find : What is the maximum velocity of the object in the time interval [0, 4]?

Solution :

The velocity is rate of change of distance w.r.t time.

Distance in terms of t is given by,

$s(t) = -t^3+3t^2+7t +4$

Derivate w.r.t. time,

$v(t)=s'(t) = -3t^2+6t+7$

It is a quadratic function so its maximum is at vertex of the function.

The x point of the function is given by,

$x=-\frac{b}{2a}$

Where, a=-3, b=6 and c=7

$t=-\frac{6}{2(-3)}$

$t=-\frac{6}{-6}$

$t=1$

As 1 lie between interval [0,4]

Substitute t=1 in the function,

$v(t)= -3(1)^2+6(1)+7$

$v(t)= -3+6+7$

$v(1)=10$

Th maximum velocity is 10 ft/s.

Therefore, the maximum velocity of the object in the time interval [0, 4] is 10 ft/s.

Please help find the greatest common factor for these two problems

vekshin1

A greatest common factor is the largest number that goes into two or more numbers (in this case two). To find the GCF of two numbers, we have to find the prime factorization (how to express a number as a product of prime numbers) and then see which numbers are common in both of the prime factorizations.

13. The prime factorization of 8 is 2 * 2 * 2. The prime factorization of 26 is 2 * 13. Looking at the prime factorizations, we can see that both of them have 2. That means that the GCF is 1 * 2 which is 2.

12. The prime factorization of 105 is 3 * 5 * 7. The prime factorization of -30 is -5 * 6. We see that the number shared 5. That means that the GCF is 5 * 1 or 5.

ITS BEEN OVER 48 HRS SINCE I FIRST POSTED THIS QUESTION PLEASE HELP ME IF YOU CAN :((((((((((!!!!!!!!!!!!!!!!!!!!!!!!!

Ksivusya [100]

Step-by-step explanation:

we know,

volume of pyramid = 1/3 × base area × height

so,

→ 1/3 × 120 × 9

→ 40 × 9 = 360 ft

so the volume of the pyramid is 360 ft².

base area = length × slant height

so, 12 × 10 = 120

hope this answer helps you dear....take care and may u have a great day ahead dear !
