What is the answer to this problem

Answer:

x = -9 and x = 5

Step-by-step explanation:

[tex] {(x + 2)}^{2} + 1 = 50[/tex]

[tex] = {x}^{2} + 4x + 4 + 1 = 50[/tex]

[tex] = {x}^{2} + 4x + 5 = 50[/tex]

[tex] = {x}^{2} + 4x + 5 - 50 = 0[/tex]

[tex] = {x}^{2} + 9x - 5x - 45 = 0[/tex]

[tex] = x \times (x + 9) - 5(x + 9) = 0[/tex]

[tex] = (x + 9) \times (x - 5) = 0[/tex]

[tex] = x + 9 = 0[/tex]

[tex] x - 5 = 0[/tex]

[tex] = x = - 9[/tex]

[tex]x = 5[/tex]

Step-by-step explanation: 8.8 x 10^ 5 = 880000

An ant can carry 0.044 pound of weight.

Important information:

Weight of an ant in standard form is:

[tex]8.8x10^{-6}=8.8\times \dfrac{1}{1000000}[/tex] pound

[tex]8.8x10^{-6}=0.0000088[/tex] pound

They can carry objects up to 5,000 times greater than their own body weight. So, the possible weight they can carry is:

[tex]0.0000088\times 5000=0.044[/tex]

Therefore, an ant can carry 0.044 pound of weight.

Answer:

k = (1 , 4)

Step-by-step explanation:

here's your solution

==> k^2 - 5k + 4. [ is expression ]

==> by using middle term split

==> k^2 - 4k - k + 4

==> taking common from each

==> k(k - 4) - 1 (k - 4)

==> (k - 1) , (k - 4).

==> k - 1 = 0

==> k = 1

==> k - 4 = 0

==> k = 4

hence , k = (1 , 4)

Answer

8.7

All the first digits are even numbers..and the numbers behind the decimal points are odd numbers

Answer:

8.7

Step-by-step explanation:

I'm assuming you want the term between 6.5 and 10.9

The sequence is aritmetic with a

common difference of 6.5 - 1.3 = 4.3 - 2.1 = 2.2

6.5 + 2.2 = 8.7

The correct margin of error for a 68% confidence interval is option D 4 centimeters.

Let's calculate the margin of error correctly for a 68% confidence interval.

To calculate the margin of error, we need to determine the critical value associated with a 68% confidence interval. For a normal distribution, the critical value is approximately ±1 standard deviation.

Given that the standard deviation is 64 centimeters, the margin of error can be calculated as:

Margin of Error = 1 * (Standard Deviation / √Sample Size)

= 1 * (64 / √256)

= 1 * (64 / 16)

= 1 * 4

= 4

Therefore, the correct margin of error for a 68% confidence interval, based on the given information, is 4 centimeters. The correct answer is option D.

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

well you know it's a 90°   so do you know what  Sin(90) is?   you should :D

I think this is kinda a trick question too b/c Opp here is also Hyp  

so it would like like    sin(90) = Opp / Hyp  but  that's  427/427 for this question.   seems kinda confusing  why ask it  that way.. huh  :/

sin(90) = 1

Answer:

number 1 the outliers....................

Answer:  B) The distribution is symmetric

Explanation:

The center of the distribution is the highest point. As you move to the left or right, the heights of each bar steadily decrease. Notice that the right hand side is a mirror copy of the left hand side. This mirroring is exactly what it means to be symmetric. If we had outliers, then we'd have bars that are further away from the main group, but we don't have such a thing happening here.

If the distribution was skewed left, or negatively skewed, then we'd have outliers that are smaller than the main group. On the other hand, if we had a skewed right (positively skewed) distribution, then we'd have outliers larger than the main group. We don't have any of these cases happening, so that's why the data isn't skewed in any way.

Answer:

w=4, 3/2

, Step-by-step explanation:

Factor out common terms in the first two terms, then in the last two terms.

w(2w-3)-4(2w-3)=0

Factor out the common term 2w-3

(2w-3)(w-4)=0

Solve for w

w=3/3,4 decimal form 1.5,4

The third side is [tex]\sqrt{42}[/tex]

So Pythagorean's theorem is the following

[tex]Short^2 + Long^2 = Hypotenuse^2[/tex]

From here we can input the following information that we know

[tex]Short^2 + 4\sqrt{3}^2 = 8^2\\Short^2 + 12 = 64\\Short^2 = 64 - 12\\Short^2 = 42\\Short = \sqrt{42}\\[/tex]

The required measure of angle value of the m2 is 48°.

Given that,
The sum of two angles m1 and m2 is 90, where m1 = 42°,
What is the value of m2 is to be determined.

The angle can be defined as the one line inclined over another line.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

m1 + m2 = 90
42 + m2 = 90
m2 = 48°

Thus, the required value of the m2 is 48°.
