40 points need NOW Simplify the expression.

Answer:

[tex]x=\pm 2\text{ or } x = \pm 2i[/tex]

Step-by-step explanation:

We are given:

[tex]0=3x^4-48[/tex]

Factor:

[tex]0=3(x^4-16)[/tex]

Difference of Two Squares:

[tex]0=3(x^2-4)(x^2+4)[/tex]

Zero Product Property:

[tex](x^2-4)=0\text{ or } x^2+4=0[/tex]

Solve:

[tex]x^2=4\text{ or } x^2=-4[/tex]

Take the square root. Since we are taking an even-root, it requires plus/minus:

[tex]x=\pm 2\text{ or } x = \pm 2i[/tex]

Answer:

3500

(0,3500)

Step-by-step explanation:

The y - intercept of the line is at (0, 3500).

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have the line models the height of a glider [y] in feet over [x] hours

The y - intercept i.e. the point where the graph cuts the [y] axis. From the graph we can see that point is (0, 3500).

Therefore, the y - intercept of the line is at (0, 3500).

Answer:

The slope of a line perpendicular to the given line will be –5/2

Step-by-step explanation:

Perpendicular lines will have a slope which is the opposite (switch from positive to negative or vice-versa) and the reciprocal (invert the fraction)

Answer:

Step-by-step explanation:

By Pythagoras' Theorem, a² + b² = c².

Substituting the values of a and b, we get:

7² + 25² = c²

49 + 625 = c²

c² = 674

c ≈ 26.0 (to 1 d.p.)

Answer:

508

Step-by-step explanation:

Take a = 12 and b = 8

[tex]\int\limits^a_b {3(f(x) - 2g(x)} \, dx =\int\limits^a_b {3(31) - 2(-17)} \, dx = 508[/tex]

Given:

The expression is

[tex]\dfrac{12\pi}{10\pi}\times \dfrac{5\pi}{6\pi}[/tex]

To find:

The value of the given expression closest to the whole number.

Solution:

We have,

[tex]\dfrac{12\pi}{10\pi}\times \dfrac{5\pi}{6\pi}[/tex]

Cancel out the common factors from each fraction.

[tex]=\dfrac{6}{5}\times \dfrac{5}{6}[/tex]

[tex]=\dfrac{6\times 5}{5\times 6}[/tex]

[tex]=\dfrac{30}{30}[/tex]

[tex]=1[/tex]

Therefore, the value of the given expression is 1.

Step-by-step explanation:

p=4

Q=2

plot an x onto the 4 on th y line and a 2 on the x line

then draw a horizontal line with the ruler provided through 4 and 2

hope it helps :)

The solution to the equations are

a) The coordinates of point P is P ( 0 , 4 ) and Q is Q ( 2 , 0 )

b) The graph is plotted with points P and Q

c) The equation of line is 4x + 2y = 8

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

4x + 2y = 8   be equation (1)

Now , the coordinates of the point P = P ( 0 , y )

The coordinates of the point Q = Q ( x , 0 )

Substituting the values in the equation , we get

when x = 0

4 ( 0 ) + 2y = 8

2y = 8

y = 4

So , the coordinates of the point P = P ( 0 , 4 )

when y = 0

4x + 2 ( 0 ) = 8

4x = 8

x = 2

So , the coordinates of the point Q = Q ( 2 , 0 )

Now , the equation of line is 4x + 2y = 8

when x = { -2 , -1 , 0 , 1 , 2 , 3 }

The values of y are y = { 8 , 6 , 4 , 2 , 0 }

So, the line is plotted in the graph

Hence , the equation of line is 4x + 2y = 8

#6) Yes; B, C, and D have lengths greater than one meter. and their areas are exactly one square meter

Step-by-step explanation:

Options B, C and D have an area of 1 square meter and their length is greater than 1 meter and the width is less than 1 meter.

Given that, Danah is planting a second strawberry patch and wants it to have an area of exactly 1 square meter.

To find the area of each different shape strawberry patch, you have to find out which options have an area of 1 square meter.

Area of rectangle formula=Length×Breadth.

Area= 1/2 × 3/2=3/4 =0.75 square meters

From option B:

Area= 2/3 × 3/2 =1 square meters

From option C:

Area= 4/5 × 5/4 =1 square meters

From option D:

Area= 2/3 × 6/4=2/2 =1 square meters

Therefore, options B, C and D have an area of 1 square meter and their length is greater than 1 meter and the width is less than 1 meter.
