How much paper will be needed to cover the rectangular pyramid shown? A. 80 cm2
B. 128 cm2
C. 144 cm2
D. 256 cm2

Answer:

4/10 = 2/5

Step-by-step explanation:

To change the decimal .4 into a fraction, we can put the 4 over 10 because the 4 is in the tenths place. Right now, we have 4/10. We can reduce this fraction (by dividing the numerator and denominator by 2) to 2/5.

Answer:

65%

Step-by-step explanation:

13/20 = 65%

20 is a 5th of 100, so multiply 13 by 5 to get the percentage.

Answer:

  h(-2) = -5

Step-by-step explanation:

Put -2 where x is and do the arithmetic.

  h(x) = x^3 -x +1

  h(-2) = (-2)^3 -(-2) +1 = -8 +2 +1

  h(-2) = -5

Additional comment

As you know, the exponent signifies repeated multiplication. For x=-2, the expression x^3 evaluates as ...

  (-2)^3 = (-2)(-2)(-2) = 4(-2) = -8

The odd power means there will be an odd number of minus signs among the factors, so the product will be negative. This means you can simplify the expression right away to ...

  (-2)^3 = -(2^3) = -8

Answer:

C. 4

Step-by-step explanation:

The mean is what people usually call the average.

The mean is the sum of the numbers divided by the number of numbers.

There were 3 games, so there are 3 scores, so the number of numbers in this case is the number of scores which is 3.

The sum of the scores is 3 + 7 + 2 = 12

mean = (sum)/(number of scores) = 12/3 = 4

Answer:

$3555.56 (2 dp)

Step-by-step explanation:

if $1600 = 45% then 1600/45 = 1%

Therefore, 100% = 1600/45 x 100 = $3555.56 (2 dp)

The y-intercept coordinate is at the point (0, 17)

Given the following function expressed as:

[tex]y = 3(x-2)^2 + 5[/tex]

The x-intercept is the point where y = 0

[tex]3(x-2)^2 + 5=0\\3(x-2)^2 = -5\\(x-2)^2 = -5/3\\x - 2 = 25/9\\x = 25/9 + 2\\x = \frac{43}{9}[/tex]

Hence the x-intercept is (43/9, 0)

The y-intercept is the point where x = 0

[tex]y=3(x-2)^2 + 5\\y=3(-2)^2 + 5\\y=12+5\\y=17[/tex]

The y-intercept coordinate is at the point (0, 17)

Answer:

The value of x is 4

Step-by-step explanation:

y = 2.5x + 65; y = 75

Now, Substitute

y = 2.5x + 65

75 = 2.5x + 65

75 – 65= 2.5x + 65 – 65

10 = 2.5x

2.5x = 10

2.5x/2.5 = 10/2.5

x = 4

Thus, The value of x is 4

Explanation:

The quadrilateral will be a trapezoid if it has exactly one pair of parallel sides. It would be isosceles if the lengths of the non-parallel sides were the same. To make the required proof, we will show two sides parallel (have the same slope) and the other two sides of different length.

It is convenient to consider the differences between the coordinates at the ends of each line segment. Here, we can use FG to mean (G -F), for example. The slope of the segment will be the ratio of the y-difference to the x-difference. The length of the segment will be the root of the sum of the squares of the differences.

EF = (-2, 0) -(-3, -5) = (1, 5) . . . . slope = 5/1 = 5; length = √(1²+5²) = √26

FG = (2, 3) -(-2, 0) = (4, 3) . . . . slope = 3/4; length = √(4²+3²) = 5

GH = (5, 1) -(2, 3) = (3, -2) . . . . slope = -2/3; length = √(3² +2²) = √13

HE = (-3, -5) -(5, 1) = (-8, -6) . . . . slope = -6/-8 = 3/4; length = √(8² +6²) = 10

__

We observe that segments FG and HE both have a slope of 3/4, so are parallel. No other segment slopes are the same, so there is exactly one pair of parallel segments.

Every segment is a different length from every other, so the trapezoid is not isosceles.
