Answer:

Step-by-step explanation:

As,

- 0.0084

When estimated, 

= - 0.008

$= \frac{ - 8}{1000}$

Then,

$- 8 \times \frac{1}{1000}$

$= - 8 \times {10}^{ - 3}$

Here,

Power of ten as observed is -3

1. An airplane moves at a constant speed of 120 miles per hour for 3 hours. How far does it go?d=rt Time Distance 1 hour 120 mil

Feliz [49]

Distance = speed rate x time

Speed rate = 120 miles per hour

Time = 3 hours

Replacing:

D = 120 mph x 3 h = 360 miles

5^11 times 5^3 = 5^?

postnew [5]

Answer:

$5^{13}$

Step-by-step explanation:

$5^{11}\times \:5^2$

Apply exponent rule : $a^b\times \:a^c=a^{b+c}$

$5^{11}\times \:5^2=5^{11+2}$

$5^{11+2}$

Add 11 +2 = 13

$=5^{13}$

Zuri quickly solved the problem and told her team, "Hey! I go it m\large \angleA = 93°, m\large \angleB = 63°, m\large \angleC =

Step2247 [10]

Answer:

Mikaya and Olivia are correct to be suspicious

Step-by-step explanation:

Sum of the angles of a triangle is always 180

But, The sum of all angles of the triangle that Zuri solved = 93 + 63 + 36 = 192 ≠ 180

So, Zuri is wrong

5x^2-2x=2 help plsmmm

Yuki888 [10]

Answer:

Presumably you're solving for x here? Without further information we'll assume that.

With that in mind, x is approximately equal to 0.86 and -0.46

Step-by-step explanation:

Let's start by putting it in the usual ax² + bx + c format.

$5x^2- 2x = 2\\5x^2 - 2x - 2 = 0\\$

let's solve it. First we'll multiply both sides by five, making the first term a perfect square:

$25x^2 - 10x - 10 = 0\\$

Now we'll add 11 to both sides:

$25x^2 - 10x + 1 = 11\\$

Which makes the left side a perfect square:

$(5x - 1)^2 = 11$

And now we can solve for x:

$(5x - 1)^2 = 11\\\\5x - 1 = \sqrt{11} \\\\5x = 1 + \sqrt{11}\\\\x = \frac{1 + \sqrt{11}}{5}$

Note that there's no apparent way of drawing the ± symbol when editing equations, so take that + sign as actually being ±.

That gives us two answers:

$x = \frac{1 + \sqrt{11}}{5}\\\\x \approx \frac{1 + 3.32}5\\\\x \approx \frac{4.32}5\\\\x \approx 0.86$ $x = \frac{1 - \sqrt{11}}{5}\\\\x \approx \frac{1 - 3.32}5\\\\x \approx \frac{-2.32}5\\\\x \approx -0.46$
