Write the following in standard form: 2x*3x^2

klemol [59]

Answer

1296

Step-by-step explanation:

The explanation is 2x is written as 2*2 = 4

then 3x is written as 3*3 = 9 so

so you do 4*9 = 36 * 2 = 1296

Surface Area of Square Pyramids

kogti [31]

The surface area of square pyramid is 64 ft²

What is square pyramid?
In terms of geometry, a square pyramid is a pyramid with a square base and four lateral faces. A pyramid is a type of polyhedron with three or more triangular faces that meet above its base (the apex). A square pyramid is a pentahedron, a three-dimensional shape with a total of five faces. The Great Pyramid of Giza is a well-known example of a real-life pyramid. When we learn about pyramids, we must also learn other concepts that are related to them, such as the volume and area of the pyramid. In this article, we will learn what a square pyramid is, its types, characteristics, surface area formulas, and volume formulas with numerous examples and solutions.

For a square pyramid, the surface area is given by the following equation:

SA = a^2 + 4(a)(h)
where a is the side length of the base and h is the slant height.
In this case, a = 4 and h = 3. Therefore,
SA = 4^2 + 4(4)(3)
SA = 16 + 48
SA = 64 ft^2

A perfect square trinomial can be represented by a square model with equivalent length and width. Which polynomial can be repres

lina2011 [118]

The correct answer is
$A) x^2 - 6x + 9$

In fact, this is a trinomial of the form $ax^2-bx+c$ , whose solutions are given by
$x_{1,2}= \frac{-b\pm \sqrt{b^2 -4ac} }{2a}$
Using this formula for the trinomial of the problem, we find:
$x1,2= \frac{6 \pm \sqrt{6^2-4\cdot 1\cdot 9}}{2} =3$
we see that this trinomial has two coincident solutions (x=3 with multiplicity 2). This means that it can be rewritten as a perfect square, in the following form:
 $(x-3)^2$

Jonah and three of his friends are splitting the dinner bill equally among theme selves. There total bill came to be $86 before

Oksana_A [137]

Answer: Required expression: $\dfrac{[ (86) + 0.18 \times(86 ) + 0.06 \times (86 )]}{4}$

Each person need to pay =$ 26.66

Step-by-step explanation:

Given: Bill amount = $86

Tip percent = 18%

Sales tax = 6%

Now, total bill = (Bill amount ) + 18% of (Bill amount ) + 6% of (Bill amount )

= $[ (86) + 18% of (86 ) + 6% of (86 )]

= $[ (86) + 0.18 x(86 ) + 0.06 x (86 )]

Total persons = 3+1 = 4

Each person need to pay= $\dfrac{\text{total bill}}{4}$

$=\dfrac{[ (86) + 0.18 \times(86 ) + 0.06 \times (86 )]}{4}\\\\=\dfrac{[ (86) (1+ 0.18 +0.06 )]}{4}\\\\=\dfrac{86(1.24)}{4}=\dfrac{106.64}{4}=26.66$

So, each person need to pay =$ 26.66

What would happen to the width of the confidence interval if Gina changed it to a 99% confidence interval?

luda_lava [24]

Answer:

The confidence interval becomes wider.

Step-by-step explanation:

The general form of a confidence interval is:

$Sample\ statistic\pm Critical\ value\times \frac{Standard\ deviation}{\sqrt{Sample\ size} }$

The critical value is based on the confidence level.

The confidence level is the probability that the true parameter value falls within a specific interval. The basic and most used confidence levels are 90%, 95% and 99%.

The confidence interval is directly proportional to the confidence interval.

Confidence Interval ∝ Confidence Level

On increasing the confidence level the confidence level widens. And on decreasing the confidence level the confidence level gets narrower.

Thus, when Gina changes the confidence interval to 99% the confidence interval becomes wider.
