Find three consecutive odd integers such that three times the sum of the first and second is 3 more than 3 times the third

Rufina [12.5K]

Answer:

3, 5, 7

Step-by-step explanation:

1st number: (2k+1)

2nd number: (2k+3)

3rd number: (2k+5), k∈Z

3*[(2k+1) + (2k+3)] = 3 + 3*(2k+5)

3*(4k+4)=3+6k+15

12k+12=18+6k

6k=6

k=1

1st number: (2k+1) = 3

2nd number: (2k+3)=5

3rd number: (2k+5)=7

Can someone please solve this ASAP?

The ladder and the wall form a right triangle.
The length is the hypotenuse = 15.
The base = 2*(15/5) = 2*3 = 6

Use pythagorean theorem to find other side of triangle:
$a^2 + b^2 = c^2 \\ \\ a^2 + 6^2 = 15^2 \\ \\ a^2 + 36 = 225 \\ \\ a^2 = 189 \\ \\ a = \sqrt{189} = 3 \sqrt{21}$

How do you find the exact value of sec θ if sin θ = -15/17 and 180 < θ < 270?

AnnyKZ [126]

For $180^\circ$ , we expect to have $\cos\theta$ . Then if $\sin\theta=-\dfrac{15}{17}$ , we have

$cos^2\theta+\sin^2\theta=1\implies\cos\theta=-\sqrt{1-\sin^2\theta}=-\dfrac8{17}$

$\implies\sec\theta=\boxed{-\dfrac{17}8}$
