5 In a scale drawing of an airplane, 1 inch equals 3 meters. The length of the actual plane is 17 meters. What is the length of

Whitepunk [10]

Answer: 5 2/3 inches

Step-by-step explanation:

From the question, we are informed that the scale drawing of an airplane is:

1 inch = 3 meters.

Since the length of the actual plane is 17 meters, the length of the plane in the scale drawing will then be:

= 17/3

= 5 2/3 inches

11 = − 3k − 22 − 8k K equals what?

butalik [34]

11 = -3k - 22 - 8k

11 = -11k - 22 added like terms (-3k and -8k)

+22 +22

33 = -11k

$\frac{33}{-11} = \frac{-11k}{-11}$

-3 = k

Answer: k = -3

If alpha beta are the roots of the equation

Vikki [24]

Answer:

Step-by-step explanation:

Hello, I believe that we can consider a different from 0.

By definition of the roots we can write.

$ax^2+bx+c=a(x-\alpha)(x-\beta)=a(x^2-(\alpha + \beta)x+\alpha \cdot \beta)\\\\\text{So we can say that:}\\\\\alpha + \beta = \dfrac{-b}{a}\\\\\alpha \cdot \beta=\dfrac{c}{a}\\\\\text{So the expected quadratic equation is}\\\\(x+\dfrac{b}{a})(x-\dfrac{c}{a})=0\\\\ \Large \boxed{\sf \bf \ (ax+b)(ax-c)=0 \ }$

Thank you

Find the zeros of polynomial function and solve polynomials equations. f(x)=24x^3-64x^2-21x+56

8090 [49]

Since this polynomial has 4 terms, factoring by grouping should be the first thing we try here.

So, we have:

$8x^2(3x-8)-7(3x-8)=0 \implies\\ (8x^2-7)(3x-8)=0$

So, we can use ZPP to find out roots:

$3x-8 =0 \implies\\ x=\frac{8}{3}\\ 8x^2-7=0 \implies \\ 8x^2=7 \implies \\ x^2=\frac{7}{8} \implies \\ x=\pm\frac{\sqrt{7}}{\sqrt{{8}}}\\ \text{Rationalizing denominator:}\\ x=\pm\frac{\sqrt{56}}{8}$

So our three roots are:

$x \in \{\frac{8}{3},\frac{\sqrt{56}}{8},-\frac{\sqrt{56}}{8}\}$

What is the answer to C?

OleMash [197]

The diagram of the sequence of circular and square tiles gives;

a) 49

b) 84

c) Will always be odd

<h3>Which method can be used to find the order of the sequence in the pattern?</h3>

Pattern 1

Number of square tiles = 1

Number of circular tiles = 8

Total number of tiles = 9

Pattern 2

Number of square tiles = 4

Number of circular tiles = 12

Total number of tiles = 16

Pattern 3

Number of square tiles = 9

Number of circular tiles = 16

Total number of tiles = 25

The number of square tiles required to make pattern n = n²

From the diagram, the number of circular tiles on the left or right side of the square tiles are 2 more than the number of square tiles, while the number of circular tiles on the top or bottom are the same as the number of square tiles, therefore;

Number of circular tiles = 2•(n + 2) + 2•n

a) The number of square tiles required to make pattern number 7 = 7² = 49

b) The number of circular tiles needed to make pattern number 20 = 2 × 20 + 2 × (20 + 2) = 84

c) The total number of circular tiles is always even while the number of square tiles has the same characteristics (even or odd) as the pattern number

Even + Odd = Odd
Even + Even = Even

When the pattern number is odd, the total number of tiles will always be odd. The correct option is therefore;

B. Will always be odd
