Answer:

Step-by-step explanation:

The absolute value function always returns a positive value, that is

| - a | = | a | = a

Given

8 - | 2g - 5 | ← substitute g = - 3.5 into the expression

= 8 - | - 7 - 5 |

= 8 - | - 12 |

= 8 - 12

= - 4 → D

A group of 85 people were asked whether or not they prefer a bagel or a muffin for breakfast and whether or not they prefer milk

gladu [14]

Answer:

The answer(s) would be WY/WZ, or WYZ (If this is multiple choice)

Step-by-step explanation:

The reasoning is that in the "IRL Equation" the polls showed that orange juice was prefered over milk, and didn't matter whether they wanted a bagel or muffin. All that matters in this equation is that it is one sided (For the 1st poll that is) and now you are able to narrow down the possibilities of the answer(s).

Write an equation for the function graphed below. The y intercept is at (0,0.5)

soldier1979 [14.2K]

<em><u>The equation of the graphed function is;</u></em>

f(x) = -3/[(x + 3)(x - 2)]

From the given graph, we see that the vertical assymptotes are at x = -3 and x = 2.

This means that at values of x = -3 or x = 2, the denominator becomes zero and the function becomes undefined.

This means that, -3 and 2 are roots of the denominator. Thus, the equation of the denominator is;

(x + 3)(x - 2)

Now,we see that the y-intercept is (0, 0.5). This means that when x = 0, y = 0.5.

Let the numerator of the equation of the function be named a.

Thus, we have;

f(x) = a/((x + 3)(x - 2))

At (0, 0.5), we have;

0.5 = a/((0 + 3)(0 - 2))

0.5 = a/(-6)

Multiply both sides by -6 to get;

-3 = a

Thus, the equation of the function is;

f(x) = -3/((x + 3)(x - 2))

Show that the three points whose position vectors are 7j+ 10k,-i + 6j+6k and - 4i + +9j + 6k form an isosceles right

Novay_Z [31]

Answer:

AB = √18 , BC=√18 and CA =4

AB²+BC² = CA² and AB=BC

ΔABC isosceles right angled triangle.

Step-by-step explanation:

Given vectors are 7j+ 10k,-i + 6j+6k and - 4i + +9j + 6k

A( 0,7,10), B( -1,6,6) C(-4,9,6)

AB⁻ = OB-OA = -I+6j+6k-(7j+10k) = -I-j-4k

AB = $\sqrt{1+1+16} = \sqrt{18}$

BC = OC-OB = -4i+9j+6k-(-I+6j+6k) = -3i+3j

BC= $\sqrt{9+9} =\sqrt{18}$

CA = OA-OC = 7j+10k - (- 4i + +9j + 6k ) = 4i-2j+4k

CA = $\sqrt{16+4+16} =\sqrt{36} =4$

Since AB²+BC² = CA²

And AB=BC

Therefore it follows that ΔABC is a right angled isosceles triangle

The sets of numbers 6, 8, 10 and 5, 12, 13 are Pythagorean triples. Use what you know about the Pythagorean Theorem and explain

9966 [12]

Well you can use the Pythagorean Theorem Formula a $x^{2}$ +b $x^{2}$ =c $x^{2}$ . Just plug in the first 2 least numbers into a and b, and see if your answer(c) is equal to the last number. Hope I helped!
