Find the distance between the two points rounding to the nearest tenth (if

1 answer:

7 0

Distance: (sqroot(x2-x1)^2 + (y2-y1)^2)
sqroot(1-3)^2 + (8-6)^2
sqroot(-2)^2 + (2)^2
sqroot(4) + 4
Square root of 8 = 2.82843
Round to nearest tenth
Solution: 2.8

Rochelle can run 800 meters in 5 minut

Semmy [17]

To find how much she can run in one minute we’re going to divide 800 by 5, to which we get 160.

She runs 160 meters in one minute.

We want to know how many meters she can run in 9 minutes.

160 * 9 = 1,440

She can run 1,440 meters in 9 minutes.

Help please!!!! ;-; staph scrolling

sertanlavr [38]

$y = 4^x \quad \to\quad y = - \frac 2 3 (4^{x+7}) - 5$

$y=4^x$

OK, we'll go in steps. First a reflection through the x axis, which negates y.

$y = -4^x$

Now a vertical scaling of 2/3

$y = -\frac 2 3 \cdot 4^x$

Now we shift seven units to the right,

$y = -\frac 2 3 \cdot 4^{x+7}$

Now down five,

$y = -\frac 2 3 \cdot 4^{x+7} - 5$

There it is.

Answer: reflection thru x axis, vertical scale 2/3, right shift 7, down 5, second choice

2. Which of the following inequalities is NOT true? F 0.309 > 0.3 G 0.329 > 0.4 H 0.104 > 0.09 J 0.9 > 0.890

Greeley [361]

Answer:

I believe that G 0.329 > 0.4 is not true.

Step-by-step explanation:

0.4 is clearly a larger number than 0.329. I feel like the key point to these are the starting numbers behind the decimal. So for 0.329 the key number would be the 3, and for 0.4 the key number would be the 4. Now which one do you think is bigger? Obviously the 0.4 for G is NOT true.
