Which recursive definition could be used to generate the sequence {1, 2,2,4,8,32}
Alexandra [31]
Given that the sequence is:
1,2,4,8,32
the recursive formula will be found as follows:
first term is=1
the sequence can be written as:
1,2,4,8,32
=(1*2^0),(1*2^1),(1*2^2),(1*2^3),(1*2^4)
thus the recursive formula will be
an=a1(r)^(n-1)
plugging the values we get:
an=1(2)^(n-1)

Which statement comparing x² + 10 and x + x + x is true when x=−5 ?
MissTica
When comparing x^2 + 10 and x + x + x equals to:
x^2 +10 is greater than x + x + x when x = -5
Because -5^2 + 10 = 25 + 10 = 35
and -5 + -5 + -5 = -15
So, 35 > -15

100 POINTS PLZ HELPPP Drag each tile to the correct box. Arrange the expressions in increasing order of their estimated values.
andrew11 [14]

Answer:

<h3>\frac{\sqrt{24}- \sqrt{54} }{\sqrt{6}} = -1   </h3><h3>\sqrt{\frac{9}{20}*\frac{10\sqrt{2} }{3\sqrt{5} } = 1.4142</h3><h3>\frac{10\pi\sqrt{2}-8\pi\sqrt{2}}{2\sqrt{2}}  = π =3.14159</h3><h3>\pi\sqrt{\frac{5}{3}}\cdot\pi\sqrt{\frac{3}{5}} = π² = 9.8696</h3>

Explanation:

1.) Rewrite √24 = \sqrt{4*6} = 2\sqrt{6}   Rewrite √54 =\sqrt{9*6}= 3\sqrt{6}

Divide both terms by the denominator; √6 cancels. 2-3 = -1

2.) Rewrite as \frac{3}{2\sqrt{5}} ×\frac{10\sqrt{2}}{3\sqrt{5}}  The 3's cancel.  10/2 = 5√2 in the numerator.

√5 × √5 = 5 in the denominator.  The 5's cancel.

That leaves √2 ≈1.4142

3.) Divide the terms in the numerator by the term in the denominator.

√2's cancel.  10π/2 = 5π   8π/2 = 4π  

Subtract and we are left with π = 3.14159

4.) \pi\sqrt{\frac{5}{3}}\cdot\pi\sqrt{\frac{3}{5}}  The square roots are reciprocals. They multiply to 1

We are left with π × π = π² ≈  9.8696

A professor believes that students who smoke cigarettes tend to have lower grades. He collects data from 1326 randomly selected
andrew11 [14]

Answer:

No.

Step-by-step explanation:

His finding that "students who smoke cigarettes do indeed tend to have lower grade point averages than students who do not smoke" implies that there can be a connection between smoking and grades. It does not specifically refer to a causal relation that smoking causes lower grades. People who make bad decisions may choose not to study well and may choose to smoke.
