Answer:

V= 68.6 m/s

Step-by-step explanation:

height above the ground t seconds after it is dropped is 675-4.9t^2

For seven seconds

Height above ground= 675-4.9(7)²

height above ground= 675-240.1

Height above ground= 434.9 m

But it's dropped from a cliff and we need to find the distance traveled from the too of the cliff

Distance= 675-434.9.

Distance= 240.1

To determine it's speed

V²= U² +2gs

V= velocity we are looking for

U= initial velocity= 0

G= acceleration due to gravity= 9.8 m/s²

s= distance covered

V²= U² +2gs

V²= 0+2(9.8)(240.1)

V²= 4705.96

V= 68.6 m/s

Answer:

Mrs Taylor should buy 45.5 yards of fabric ( 45.5364 actually but rounded to the nearest tenth)

Step-by-step explanation:

Here in this question, we are interested in calculating the total yards of fabric that Mrs Taylor should buy.

From the question, we are made to know that one uniform requires 26 inch of fabrics and she wants to make a total of 63 uniforms

The total inches of fabric needed is thus; 26 * 63 = 1,638 inches of Fabrics

But we want our answer in yards.

Mathematically;

1 inch = 0.0278 yard

1638 inches = x yard

x = 1638 * 0.0278 = 45.5364 yards which is approximately 45.5yards

Answer:

Width of the new tv= 65.44 inches

Height of the new tv = 36.41 inches

If the newer television has an aspect ratio of 16:9, will the new tv fit in the old entertainment center?

Since the old entertainment set has a dimension of 70 inches by 35 inches

,new TV set, has dimension of 65.44 inches by 36.81 inches, the new TV may not be able to fit into the old entertainment set properly because it is 1.81 inches higher than the entertainment set.

Step-by-step explanation:

The newer TV set has an aspect ratio of 16: 9 and it is 75 inches

We are going to make use of Pythagoras theorem

= Width² + Height ² = Size of TV²

Width = 16x

Height = 9x

75² = (16x)² + (9x)²

5625 = 256x² + 81x²

5625 = 337x²

x² = 5625/337

x² = 16.691394659

x = √16.691394659

x = 4.0855103303

Approximately = 4.09

Hence, we can find the width and height of the new TV

Width = 16x

Width = 16 × 4.09

Width = 65.44 inches

Height = 9x

Height = 9 × 4.09

Height = 36.81 inches

Hence, the dimensions of the new TV set = 65.44 inches by 36.81 inches

If the newer television has an aspect ratio of 16:9, will the new tv fit in the old entertainment center?

Since the old entertainment set has a dimension of 70 inches by 35 inches

,new TV set, has dimension of 65.44 inches by 36.81 inches, the new TV may not be able to fit into the old entertainment set properly because it is 1.81 inches higher than the entertainment set.

Step-by-step explanation:

[tex] \sf{(4 + 2i) + ( - 3 - 5i)}[/tex]

When there is a ( + ) in front of an expression in parentheses, there is no need to change the sign.

That means the expression remains the same.

Just remove the parentheses

  1 -3i

Step-by-step explanation:

For purposes of addition or subtraction, the i can be treated as though it were a variable. Terms can be collected in the usual way.

  4 +2i +(-3 -5i) = 4 +2i -3 -5i

  = (4 -3) +i(2 -5) = 1 -3i

Answer: Choice C)

(1/30)*(1/29)

Explanation:

Jack has a 1/30 chance of being picked since he is 1 person out of 30 total. After his name is picked, and not put back, there are 30-1 = 29 names left. The chances Jill is picked is 1/29. The two fractions are multiplied to get the overall probability both are picked.

Answer:

9

Step-by-step explanation:

Working backwards, the blank box between the 7 and 4 at the end must be 9 in order for the three digits to equal 20.  Then we see the pattern of 947 repeated.  The whole number would be 94794794794794.  That way, any three consecutive numbers would be 20.  The number in the box marked a would be 9.

Answer:

  30500 = 3.05·10^4

Step-by-step explanation:

Your calculator can do this for you. You may need to set the display to scientific notation, if that's the form of the answer you want.

__

This can be computed by converting both numbers to standard form:

  (5·10^2) +(3·10^4)

  = 500 +30000 = 30500 = 3.05·10^4

__

Addition of numbers in scientific notation in general requires that they have the same power of 10. It may be convenient to convert both numbers to the highest power of 10.

  5·10^2 + 3·10^4

  = 0.05·10^4 +3·10^4 . . . . now both have multipliers of 10^4

  = (0.05 +3)·10^4

  = 3.05·10^4

Answer:

See below.

Step-by-step explanation:

4)

So we have the expression:

[tex](-6n^{-3})^2[/tex]

We can use the power of a product property, where:

[tex](ab)^n=a^n\cdot b^n[/tex]

So:

[tex]=(-6)^2\cdot(n^{-3})^2[/tex]

For the left, -6 squared is the same as -6 times -6. This equals positive 36.

For the right, we can use the power of a power property. The property says that:

[tex](a^n)^k=a^{nk}[/tex]

So:

[tex](n^{-3})^2=n^{(-3)(2)}\\=n^{-6}[/tex]

So, all together, we have:

[tex]=(-6)^2\cdot(n^{-3})^2\\=36n^{-6}[/tex]

6)

We have the expression:

[tex]-\frac{3x^0}{x^4}[/tex]

First, note that anything to the zeroth power (except for 0) is 1, thus, x^0 is also 1. Simplify:

[tex]=-\frac{3}{x^4}[/tex]

And that's the simplest we can do :)

Notes for 6)

We can put the x^4 to the numerator. Recall that when you put an exponent to opposite side, you put a negative. In other words:

[tex]x^n=\frac{1}{x^{-n}}[/tex]

And vice versa:

[tex]\frac{1}{x^{-n}}=x^n[/tex]

So, we can write the above as:

[tex]=-\frac{3}{x^4}\\=-\frac{3}{x^{-(-4)}}\\=-3x^{-4}[/tex]

However, traditionally, we want only positive exponents, so this wouldn't be correct.

Answer:

Step-by-step explanation:

x^m×x^n=x^{m+n}

x^m÷x^n=x^{m-n}

[tex]\frac{1}{x^m} =x^{-m}\\x^{-n}=\frac{1}{x^n} \\(xyz)^m=x^m\times y^m \times z^m \\(x^m)^n=x^{mn}[/tex]

[tex]x^0=1[/tex]

Answer:

x=3

Step-by-step explanation:

2/3x+15=17

first subtract 15 from both sides

2/3x=2

multiply by 3 to eliminate the fraction

2x=6

divide by 3

x=3

Answer:

x=3

Step-by-step explanation:

2/3x +15 = 17

2/3x = 17-15

2/3x = 2

x = 2  /  2/3

x = 2/1  *  3/2

x = 6/2

The standard form of a polynomial has the exponents decreasing left to right. Here, the exponents are 4, 3, 1, 0, so are decreasing left to right. The expression is in standard form.

Answer:

Use a graphing calc.

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

For the third equation, m = 2

y = 2x + b

3 = 3(2) + b

3 = 6 + b

b = -3

y = 2x - 3
