Answer:

Henry will buy 18 gift bags and 18 bows in 3 packs of gift bags and 2 packs of bows.

Step-by-step explanation:

Least Common Multiple (LCM)

Is the smallest positive number that is a multiple of two or more numbers. To find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number.

Since Henry wants to buy the same number of gift bags and bows and they are sold in packs with different quantities, we must find the LCM between those numbers.

Gift bags are sold in packs of 6. Bows are sold in packs of 9.

List the prime factors of 6: 2,3

List the prime factors of 9: 3,3

Multiply: 2*3*3=18

The  LCM is 18. This means Henry will buy 18 gift bags and 18 bows in 3 packs of gift bags and 2 packs of bows.

Answer:

When we do not have anything cut of the rectangle, the area is:

8in*5in = 40in^2.

Now, when we cut squares of length x in the corners, the measures of the base will be:

8in - 2*x

5in - 2*x

We subtract two times x in each case because we cut the squares in the four corners. (below you can see a drawing of this situation, where the doted rectangle is the area that we want to calculate)

Then the area as a function of x is:

A = (8in - 2*x)(5in - 2*x) = 40in^2  + 4*x^2 - 26*x

Step-by-step explanation:

Subtract 10y from both sides of the equation:

  10y -10y = 10y -10y -2

24+40-10

64-10

54

Answer:

Here's how to solve this.

Step-by-step explanation:

a=5 b=5 c=8

so

3*8 + 5*8 - 2*5

Well 3*8=24

5*8= 40

2*5=10

Therefore 24 + 40 - 10.

24 + 40= 64

64 - 10= 54

would be your answer.

I hope this helps.

Answer:

yes

Step-by-step explanation:

divide each by 7 =

21/7 = 3

28/7 =4

35/7 = 5

3,4,5 are always a perfect triple, and multiples of 345 are perfect triples as well. Therefore, they are sides of a right triangle.

Answer: you got it right, it is the one that is blue highlighted.

Let they be x.

Cost of textbooks + laptops cant greater than total amount.

(cost of 1 textbooks * number of textbooks) + (cost of 1 laptop * number of laptops ≤ 6500

(30*116) + (x*439) ≤ 6500

3480 + 439x ≤ 6500

439x ≤ 3020

x ≤ 6.8(approx)

Last natural number is 6, says, they can buy 6 laptops at max.

Answer:

The ball will not reach a height of 41 meters.

The discriminate is 784

Step-by-step explanation:

You know that the height h of the ball, in meters, at time t seconds is modeled by the function h(t) = - 5*t² + 2*t + 39

To find out if the ball will reach a height of 41 meters, you must calculate the maximum of the function, that is, the highest or highest point on the graph.  That is, the maximum in a function f is the largest value that the function takes.

The vertex is a point that is part of the parabola, which has as its ordinate the maximum value (as in this case) or minimum value of the function. That is, the vertex is the maximum of the function (as in this case) or minimum.

In this case, the maximum of t is obtained by:

[tex]t=\frac{-b}{2*a}[/tex]

Being a=-5 and b=2 (comparing with a quadratic function of the form: f(x)=a*x² + b*x +c)

[tex]t=\frac{-2}{2*(-5)}[/tex]

t= 0.2

The maximum height value must be obtained by substituting the previously calculated value of t in the function:

h(0.2) = - 5*0.2² + 2*0.2 + 39

h(0.2)=39.2

So the maximum height the ball will reach is 39.2 meters. The ball will not reach a height of 41 meters.

The discriminate of a quadratic function is:

Δ=b²-4*a*c

In this case, being a=-5, b=2 and c=39, the discriminate is:

Δ=2²-4*(-5)*39

Δ= 4+780

Δ= 784

The discriminate is 784

The first derivative test is the process of analyzing functions using their first derivatives in order to find their extreme point.

No, ball can not reach at height of 41 meters.

Since, The height h of the ball, in meters, at time t seconds is modeled by the function  [tex]h(t)=-5t^2+2t+39[/tex]

To find maximum height where can ball reach. We use first and second derivative test.

[tex]h(t)=-5t^2+2t+39\\\\\frac{dh}{dt}=-10t+2[/tex]

Now, equate above derivative to zero.

 [tex]-10t+2=0\\\\t=1/5[/tex]

Now, find second derivative

[tex]\frac{d^{2}h }{dt^{2} } =-10[/tex]  , Which is less than zero.

Therefore, at t= 1/5 second , will give maximum height that can ball reach.

So,  h(1/5) = 39.2 meters.

That is, ball can reach at 39.2 meters.
