7 0

Answer

\sqrt{34}

Step-by-step explanation

You would use the pythagorean theorem for this problem. The point on the y-axis is 5 away from (0,0). The point on the x-axis is 3 away. You would square these, leading from

5+3 to

25+9=\sqrt{34}

Answer is \sqrt{34}.

Solve 5x2 + 13x + 6 = 0
Ede4ka [16]

Answer:

x = - 2, x = - \frac{3}{5}

Step-by-step explanation:

Given

5x² + 13x + 6 = 0

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 5 × 6 = 30 and sum = + 13

The factors are + 10 and + 3

Use these factors to split the x- term

5x² + 10x + 3x + 6 = 0 ( factor the first/second and third/fourth terms )

5x(x + 2) + 3(x + 2) = 0 ← factor out (x + 2) from each term

(x + 2)(5x + 3) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

5x + 3 = 0 ⇒ 5x = - 3 ⇒ x = - \frac{3}{5}

Write these numbers in order from least to greatest <br> 0.65, 2/3, 3/5 , 0.5
svp [43]

Answer:

<h2>0.5, 3/5, 0.65, 2/3</h2>

Step-by-step explanation:

Convert the fractions to the decimals (you can use the calculator):

2/3 = 2 : 3 = 0.6666...

3/5 = 3 : 5 = 0/6

We have

0.65

0.666...

0.6

0.5

The order from least to greatest:

0.5

0.6

0.65

0.666..

\begin{array}{c|c|c|c|c}0&.&5\\0&.&6\\0&.&6&5\\0&.&6&6&6...\end{array}

WILL MARK BRAINLIEST ASAP!
musickatia [10]

Answer:

D -24/25

Step-by-step explanation:

sin(2x) = 2sin(x)cos(x)

cos(x) = ⅘

sin²(x) = 1 - cos²(x) = 1 - (⅘)²

sin²(x) = 9/25

sin(x) = -⅗

(Because 4th quadrant)

sin(2x) = 2(-⅗)(⅘)

= -24/25

At one time the aircraft is 150 m above the surface, the submarine is 25 m below the surface, and the underwater robotic vehicle
EastWind [94]

Answer:

175 meter is  difference in height between the submarine and the aircraft

Step-by-step explanation:

The height of aircraft above the surface = 150 meter

Depth at which the submarine lies below the surface = 25 meter

Depth at which the underwater robotic vehicle  below the surface = 186 meter

Difference in height between the submarine and aircraft is equal to

25 +150 = 175 meter
