Answer:

Just find a pattern. In this instance, every number increases by one less than the previous increase.

Step-by-step explanation:

For example, 2 increases by 8 to 10. Then it increases by 7 to get to 17. Then it increases by 6, then by 5, and it will continue in that way for the next two, increasing by 4 to get 32, and then increasing by 3 to get to 35.

2,10,17,23,28,32,35

=> the next numbers are 28+4 = 32, and 32+3 = 35

a1 = 2

a2 = a1+8

a3 = a2+7

a4 = a3+6

a5 = a4+5

a6 = a5+4

a7 = a4+3

If A ⊂ B, then which of the following describes the relationship between A and B?
Amanda [17]

A set is a well-defined collection of objects. Each object in a set is called an element of the set. Two sets are equal if they have exactly the same elements in them.

A set is a subset of another set if all elements of the set are elements of the set . In other words, the set is contained inside the set . The subset relationship is denoted as A ⊂ B .The relationship of one set being a subset of another is  also called inclusion  or we can say Set B may have more elements than A does.

Option 4 .Set B may have more elements than A does is the right answer.

A cable hangs between two poles of equal height and 35 feet apart. At a point on the ground directly under the cable and x feet
gayaneshka [121]

Answer:

293.38 pounds

Step-by-step explanation:

We are given that

Distance between poles=35 feet

h(x)=10+0.1(x^{1.5})

Weight of cable=10.4 per linear foot

We have to find the weight of the cable.

Differentiate w.r.t

h'(x)=0.1(1.5)x^{0.5}=0.15x^{0.5}

s=2\int_{0}^{17.5}\sqrt{1+(h'(x))^2}dx

s=2\int_{0}^{17.5}\sqrt{1+(0.15x^{0.5})^2}dx

s=2\int_{0}^{17.5}\sqrt{1+0.0225x}dx

Let 1+0.0225x=t

dx=\frac{1}{0.0225}dt

s=\frac{2}{0.0225}\int_{0}^{17.5}\sqrt{t}dt

s=\frac{2}{0.0225}\times\frac{2}{3}[t^{\frac{3}{2}}]^{17.5}_{0}

s=2\times \frac{2}{3\times0.0225}[(1+0.0255x)^{\frac{3}{2}]^{17.5}_{0}

s=\frac{4}{3\times 0.0225}((1+0.0225(17.5))^{\frac{3}{2}-1)

s=28.21

Weight of cable=28.21\times 10.4=293.38pound
