The polynomial which shows algebra tile configuration is \rm -x^2 + 3x - 4.

We have to determine

Which polynomial represents the algebra tile configuration shown?

According to the question

Polynomials are defined as the sums of terms that are represented in the form of k-xⁿ, where k is any number and n is a positive integer.

The polynomial represented by algebra tiles is \rm -x^2 + 3x - 4

In the given tiles,

2 tiles for = \rm -x^2

3 tiles for = x

4 tiles for = -4

Now, putting the like terms together, the equation becomes:

\rm (x^2+-2x^2) + 3(x+  x+ x ) -(1+1+1+ 1)

The like terms can be added such that:

\rm -x^2 + 3x - 4

Hence, the polynomial which shows algebra tile configuration is \rm -x^2 + 3x - 4.

Idk what to do i need help asap please & thank you
8090 [49]

Answer:

170(1.3)^{t}

Step-by-step explanation:

For this formula it would be exponential growth. The formula for exponential growth is: y = a(1+r)^{t}

a is the initial value

r is the growth rate

t is the number of time intervals that have passed in the given situation

In this problem, you would substitute the r for the given percent (0.3) and substitute the a for 170 as the initial value. The equation would then be:

170(1.3)^{t}

i hope this explanation is helpful

TotCo is developing a new deluxe baby bassinet. If the length of a newborn baby is normally distributed with a mean of 50 cm and
Delicious77 [7]

Answer:

<em>The interior length of the bassinet to ensure that 99 percent of newborn babies will fit   = 1.7 cm</em>

Step-by-step explanation:

<u><em>Explanation:</em></u>-

<em><u>step(i):</u></em>-

Given mean of population = 50 cm  

<em>standard deviation of Population = 5 cm</em>

<em>Given Margin of error = 10 cm</em>

<em>The Margin of error is determined by </em>

<em></em>M.E = \frac{Z_{\alpha } S.D}{\sqrt{n} }<em></em>

<u><em>Step(ii)</em></u><em>:-</em>

<em>Given level of significance ∝ = 99 % or 1 %</em>

Z₀.₀₁ = 2.576

10 = \frac{2.576 X 5}{\sqrt{n} }

\sqrt{n}  = \frac{2.576 X 5}{10}

√n = 1.3

squaring on both sides , we get

<em>n = 1.69≅ 1.7 cm</em>

<u><em> Final answer:</em></u>-

<em>The interior length of the bassinet to ensure that 99 percent of newborn babies will fit   = 1.7 cm</em>
