Graph the first six terms of a sequence where a1 = 3 and d = −10.
Aleks [24]

Answer:

Step-by-step explanation:

nth term = (n-1)th term + common difference

d = -10

a₁ = 3

a₂ = a₁ + d = 3 + (-10) = -7

a₃ = a₂ + d = -7 + (-10) = -17

a₄ = a₃ + d = -17 + (-10) = -27

a₅ =a₄ + d = -27 + (-10) = -37

a₆ = a₅ + d = -37 + (-10) = -47

First six terms: 3 , -7 , -17, -27, -37 , -47

What is the range of the function y = StartRoot x + 5 EndRoot?
Aleks [24]

Answer: y≤0

Step-by-step explanation:

Looking at the question, I'm assuming the equation is y=\sqrt{x+5}.

To find the range if this equation, it would be best to know that the graph of a square root looks like. Knowing that x=-5, the graph starts at -5 and then increases slowly to the right. Since there are no restrictions to this equation, the graph goes towards infinity.

Find the value of x.<br> 7<br> Х<br> 3<br> Z<br> X =√[?]<br><br> Pls help explain !!
Alisiya [41]

Answer:

Answer:

 x = √70

Step-by-step explanation:

The triangles shown are all similar, so the corresponding sides are proportional.

 hypotenuse/long side = x/7 = (7+3)/x

Cross-multiplying gives ...

 x^2 = 7(10)

 x = √70

_____

You will note that the value of x (the long side) is the geometric mean of the long segment and the whole hypotenuse.

A similar "geometric mean" relation holds for the short side:

 BC = √(CD·CA)

There is yet another "geometric mean" relation that holds for the altitude:

 BD = √(CD·AD)

Step-by-step explanation:
