Answer:

(4x^3 - 9)(4x^3 + 9)

Step-by-step explanation:

16x^6 - 81

write this in the form of a^2 - b^2

(4x^3)^2 - (9)^2

since a^2 - b^2 = (a + b)(a - b) . Write,

(4x^3 - 9)(4x^3 + 9)

Answer:

OK , so I'll follow all your instructions:

x² + 12x - x + 24 = 0

x² + 11x + 24 = 0.......product = 24, sum= 11 & factors = 3 & 8

(x² + 3x ) (+ 8x + 24) =0

x ( x + 3) + 8 ( x + 3)=0

( x + 3 ) ( x + 8)=0

x +3 = 0 or x + 8= 0

x = -3. or x = -8

Answer:

In 5 years I will have $ 1,151.71.

Step-by-step explanation:

To determine, if I put 700 into a savings account that's earns 1% interest compound monthly, how much will I have in 5 years, the following calculation must be performed:

700 x (1 + 0.01 / 12) ^ 12x5 = X

700 x (1 + 0.008333) ^ 60 = X

700 x 1.64530 = X

1,151.71 = X

Therefore, in 5 years I will have $ 1,151.71.

Answer: 12.48

Step-by-step explanation:

38x38+bxb=40x40

1444+b=1600

1600-1444=156

[tex]\sqrt156[/tex]=12.48

The base of the house is 12.48 foot far from the foot of the ladder.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

|AC|^2 = |AB|^2 + |BC|^2    

It is given that A 40-foot ladder reaches 38 feet up the side of a house.

We need to find that How far from the base of the house is the foot of the ladder.

Using Pythagoras theorem, we get;

[tex]38^2 + b^2 =40^2\\\\1444 + b^2 = 1600\\ \\b^2 = 1600 - 1444 \\\\b^2= 156\\\\b = 12.48[/tex]

Therefore, the base of the house is 12.48 foot far from the foot of the ladder.

Answer:

The coefficient of the squared term of the equation is 1/9.

Step-by-step explanation:

We are given that the vertex of the parabola is at (-2, -3). We also know that when the y-value is -2, the x-value is -5. Using this information we want to find the cofficient of the squared term in the parabola's equation.

Since we are given the vertex, we can use the vertex form:

[tex]\displaystyle y=a(x-h)^2+k[/tex]

Where a is the leading coefficient and (h, k) is the vertex.

Since the vertex is (-2, -3), h = -2 and k = -3:

[tex]\displaystyle y=a(x-(-2))^2+(-3)[/tex]

Simplify:

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

We are also given that y = -2 when x = -5. Substitute:

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

Solve for a. Simplify:

[tex]\displaystyle \begin{aligned} -2&=a(-3)^2-3\\ 1&=9a \\a&=\frac{1}{9}\end{aligned}[/tex]

Therefore, our full vertex equation is:

[tex]\displaystyle y=\frac{1}{9}(x+2)^2-3[/tex]

We can expand:

[tex]\displaystyle y=\frac{1}{9}(x^2+4x+4)-3[/tex]

Simplify:

[tex]\displaystyle y=\frac{1}{9}x^2+\frac{4}{9}x-\frac{23}{9}[/tex]

The coefficient of the squared term of the equation is 1/9.

Answer:

radius is 8 ft

Step-by-step explanation:

circumference formula is 2pi r

so if the circumference is 16 pi, we divide it by 2 to get 8 pi and divide it by pi to get 8.

Answer:

8  ft

Step-by-step explanation:

The circumference is given by

C = 2 * pi *r

16 pi = 2 * pi *r

Divide each side by 2 pi

16 pi / 2 pi = 2 pi r / 2 pi

Answer:

The values of h = -2 and 4

The value of k = -3

Step-by-step explanation:

Putting x=5 in the given equation,

x²+(k-1)x-5=0

or, 5²+(k-1)*5-5=0

or, 25+5k-5-5=0

or, 15+5k=0

or, 5k=-15

or, k=-3

putting the value of k and the other root (h+1) in the given equation,

(h+1)²+(-3-1)(h+1)-5=0

if you solve this, you'll get h = -2 and h = 4.

The domain is the span of the x-values, and the range is the span of the y-values. In each, we are looking for the smallest and largest values.

Domain: x starts at -7, and goes to infinity (we cannot see an end)

(-7, infinity)

Range: y starts at negative infinity (we cannot see where it would start), and goes to 3

(negative infinity, 3)

Answer:

200π cm²

Step-by-step explanation:

Applying,

TSA = πrl+πr²

TSA = π(r²+rl)............. Equation 1

Where TSA = Total surface area, r = radius of the base, l = slight height of the cone

To get l we apply pythagoras theorem

From the diagram,

l² = 15²+8²

l² = 225+64

l² = 289

l = √289

l = 17 cm

Given: r = 8 cm

Substitute these values into equation 1

TSA = π(8²+17×8)

TSA = π(64+136)

TSA = π(200)

TSA = 200π cm²

Answer:

15. Area of parallelogram = bh

    b = 9m

    h = 4m

    a = 9*4 = 36m^2

   You can also use the rectangle property here.

    a = l*b

    l = 9

    b = 6

    a = 9*6 = 54 m^2

    Though I would prefer the first one better.

16. Area of triangle = 1/2*bh

    b = 17m

    h = 3

    a = 17*3/2 = 51/2 = 25.5m^2

18. Area of a trapezium = a+b/2*h (a and b are two parallel sides and h the            height)

a = 15

b = 7

h = 15

a = 15+7/2*15 = 22/2*15 = 11*15 = 165m^2

19. Area of triangle = 1/2*bh

    b = 24

    h = 7

    a = 24*7/2 = 168/2 = 84

Answer:

9.5 miles

Step-by-step explanation:

Since her route is in the shape of a triangle, total distance travelled can be determined by calculating the perimeter of a triangle.

A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees

The perimeter of a triangle = sum of the side lengths

The total distance travelled can be determined by adding the miles she rode

2.3 + 3.4 + 3.8 = 9.5 miles
