QUESTION POSTED AT 14/01/2020 - 03:06 PM

(-8x^6) / (4x^3) can be broken down as (-8/4) * (x^6/x^-3)

you should know that -8/4 is -2

the second part is dividing variables at different powers which is kinda like subtracting powers

think of it as x ^ (6-(-3))

you get x^9

-2 * x ^9

= -2x^9

The two events are independent, so the probability of both happening is the product of the two.

Probability of picking an even number is 3/6=1/2

Probability of picking the letter A is 1/3 = 1/3

Product of probability of two independent events = (1/2)(1./3)=1/6.

QUESTION POSTED AT 21/01/2020 - 09:48 AM

Answer: D. (-14, -54)

WORKINGS

According to Table 1: y = 4x + 2 … (Equation I)

According to Table 2: y = 3x – 12 … (Equation II)

Substitute the value of y in equation I (4x + 2) for y in Equation II to solve for x

y = 3x – 12

4x + 2 = 3x – 12

4x – 3x = -12 – 2

x = -14

Substitute -14 for x in Equation I to solve for y

y = 4x + 2

y = 4(-14) + 2

y = -56 + 2

y = -54

Therefore, x= -14; y = -54

To determine the nature of the graph and on what points will it intersect the x - axis, determine the roots of the graph first. One way to find the roots is to use the quadratic formula, x = (-b +/- sqrt(b^2 - 4ac))/ 2a. Using this formula we get, x = -2.5. Thus, the answer is letter B.

**Answer:**

As given Point A is the center of the circle.

We will answer this question by considering all the options.

Option 1. FA : AE [ Both FA and EA are radius of circle .So their ratio can't be equal to 1:2.]

Option 2. CB : FE [ CB is a chord and FE is a Diameter as length of Chord not given, So we can't Predict about their Ratio.]

Option 3: FE : AH [As FE is the Diameter and AH is radius.Diameter = 2 × Radius,So FE : AH=2:1]

Option 4 : AH : FE [Explained above AH: FE=1:2]

Option 5: AH : AD [AH is the radius of the circle and D is any point on AH So their ratio can't be 1:2.]

**Option (d) AH : FE = Radius : Diameter=1:2 is true.**

The only choice that doesn't imply something absurd is 'b' .

____________________________________________

OK. I didn't want to have to do this, but it seems to be necessary:

-- We have an isosceles triangle.

Two sides are equal and the third one is different.

That means that two angles are equal and the third one is different.

-- All 3 angles in a triangle always add up to 180°

One angle is 130°. If that one were one of the two equal angles,

then just those two would add up to 260° even without the 3rd angle.

So the 130° angle must be the one that's different.

-- The other two angles add up to (180 - 130) = 50°.

And they're the ones that are equal.

So <A and <C are each 25° .

-- Choice-a). <A=15° and <C=35°. No. Then the triangle wouldn't have

two equal angles.

-- Choice-b). <A + <B = 155°. Yes. Given <B=130, and we calculated <A=25°.

-- Choice-c). <A+<C = 60° . No. They're each 25°.

If they were each 60°, then the total

for the triangle would be (130+60+60) = 250° .

-- Choice-d). <A20=20° and <C=30°. No. Then the triangle wouldn't have

two equal angles.

**Answer:**

**option (a) shows that the commutative property do not holds under subtraction.**

**(a) 5 – 1 ≠ 1 – 5 **

**Step-by-step explanation:**

Given : Some options showing operation subtraction.

We have to choose out of given options which one shows that the commutative property doesn't work under subtraction.

**Commutative property under addition states that for given any two positive numbers and b then following property holds ** that is it is irrespective of place the numbers are arranged like 2 + 3 = 3+ 2

but when we subtract two number the order or place of number matters.

Like 3 - 2 = 1 but 2 - 3 = -1 ≠ 1

**Thus, the commutative property do not holds under subtraction.**

** 5 – 1 = -4 ≠ 1 – 5 = -4 **

**So, option (a) shows that the commutative property do not holds under subtraction.**

Possible side lengths of a triangle are determined by the triangle inequality:

a+b>c

where a and b are the shorter sides, (i.e. c is the longest side).

Note that equality does not hold, because it will make a "triangle" with an angle equal to zero degrees.

An example, choice a, 3+5<9, so they are not possible side lengths.

EDITED 2018-02-26

As already indicated in comments, (4, 8, 10) is a feasible set of sides for triangles because the shorter sides are 4 and 8, and the sum (12) is greater than the third side (10).
