Mathematics
1 answer:
Licemer1 [7]3 years ago
8 0

Answer:

b perpendicular

Step-by-step explanation:

all that is needed to do is the Y2 - y1 / X2 - X1 formula and then compare the two slopes making sure they are inverse opposites

Line 1)      -7 -8 / -3 -2  X= 3X

Line 2)      -3 - 0 / 12 - 3  X = -1 / 3X

Because they are inverse opposites of each other they are perpendicular had they had the exact same slopes they would have been parallels.

Evaluate the following using<br> powers of ten rules.<br> 104)1.042
Alinara [238K]

Answer:

0.0001042

Step-by-step explanation:

Power of tens rule states that if the denominator of a fraction has the positive power of 10, decimal in the numerator will be shifted to the left by the same number of places as exponent.

10⁴) 1.042 = \frac{1.042}{10^4}

In the denominator of the given fraction, exponent of 10 = +4

So the decimal in numerator will be shifted left by 4 places.

\frac{1.042}{10^4}=0.0001042

Therefore, answer is 0.0001042

Identify the graph that has a vertex of (1,-1) and a leading coefficient of a=2.
soldi70 [24.7K]

<u>ANSWER</u>

f(x) = 2 ({x  - 1)}^{2} - 1

<u>EXPLANATION</u>

The vertex form of a parabola has equation:

f(x) = a ({x  - h)}^{2}  + k

where V(h,k) is the vertex of the parabola and 'a' is the leading coefficient.

From the question, we have that, the vertex is

(1,-1)

and the leading coefficient is

a= 2

We substitute the vertex and the leading coefficient into the vertex form to get:

f(x) = 2 ({x  - 1)}^{2}  +  - 1

We simplify to get:

f(x) = 2 ({x  - 1)}^{2} - 1

The graph of this function is shown in the attachment.
