Answer:

Step-by-step explanation:

By applying Pythagoras theorem in the given right triangles,

(Hypotenuse)² = (leg 1)² + (leg 2)²

a). (123.1)² = x² + (48.7)²

x² = 15153.61 - 2371.69

x² = 12781.92

x = 113.06 cm

b). (117)² = (82)² + x²

x² = 13689 - 6724

x = 83.46 mm

C). (117)² = t² + (10.3)²

t² = 13689 - 106.09

t² = 13582.91

t = 116.55 cm

Use a graphing calculator to sketch the graph of the quadratic equation, and then give the coordinates for the x-
Umnica [9.8K]

Given:

The quadratic equation is

y=6x^2-15x+6

To find:

The x-intercepts of the given equation.

Solution:

We have,

y=6x^2-15x+6

Splitting the middle term, we get

y=6x^2-12x-3x+6

y=6x(x-2)-3(x-2)

y=(x-2)(6x-3)

For x-intercepts, y=0.

(x-2)(6x-3)=0

Using zero product property, we get

x-2=0\text{ and }6x-3=0

x=2\text{ and }6x=3

x=2\text{ and }x=\dfrac{3}{6}

x=2\text{ and }x=0.5

So, the x-intercepts are (0.5,0) and (2,0).

Therefore, the correct option is a.

What is the probability of drawing a black ace followed by a heart out
Verdich [7]

Correct option C) 0.98%

<u>Step-by-step explanation:</u>

We know that  , there are 2 black ace cards out of 52 cards in a deck & 13 hearts out of 52 cards . Here we have to tell What is the probability of drawing a black ace followed by a heart out  of a deck when the cards aren't replaced . Let's find out:

Firstly , a black ace is drawn , so probability :

⇒ P(Black) = \frac{2}{52}

Now , A heart is drawn out of 51 cards ( as one black ace is already drawn !):

⇒ P(Heart) = \frac{13}{51}

So , Probability of occurring both events is :

⇒ P(Black)(P(Heart))

⇒ \frac{2}{52} (\frac{13}{51} )

⇒ 0.0098

Percentage = 0.0098(100) = 0.98%

Therefore , Correct option C) 0.98%

What are the rules to solving equations by multiplying or dividing?
Andreas93 [3]

Answer:

In order to move a number that is multiplied or divided by the variable, make sure to inverse both sides! That means, if the number is multiplied, you divide it by both sides. If it's divided, you must multiply it by both side; steps so that you can apply them to harder equations.

Sorry if this didn't help! I hope it did though, good luck. <3
