Answer:

26 inches

Step-by-step explanation:

You need to add 3+5+7+7+4= 26 because you need to find the area of the figure which the inches are area to add and get how many inches in the figure. Sorry if you don't get it but the answer is 26 inches.

for A (xa ; ya) and B (xb ; yb)

the slope is (yb - ya) / (xb - xa)

here :

slope = - 3/4 = (4 - r) / (-3 - (-7))

(4 - r) / 4 = - 3/4

so 4 - r = - 3

then r = 7

check

points (-7 ; 7) and (-3 ; 4)

slope = (4 - 7) / (-3 - (-7) = -3/4

Answer:

$17

Step-by-step explanation:

So first

The total money John have is $20

then he earned $5 which means $20+$5 = $25

After that he spent $10 = $25- $10 = $15

Again earned $5 = $15+$5=$20

At last spent $3 = $20-$3=$17

Hence the total money he owe or have left is $17

The building should be 1.024 meters high and unfortunately there are no buildings with such height in the world.

In this question we must use definition of geometric progression to predict initial height ([tex]h_{o}[/tex]), in meters, in terms of current height ([tex]h[/tex]), in meters, and number of bounces experimented by the ball ([tex]n[/tex]). The expression is described below:

[tex]h = h_{o}\cdot \left(\frac{1}{2} \right)^{n}[/tex]   (1)

If we know that [tex]n = 10[/tex] and [tex]h = 1\,m[/tex], then the initial height is:

[tex]1 = h_{o}\cdot \left(\frac{1}{2} \right)^{10}[/tex]

[tex]h_{o} = 2^{10}[/tex]

[tex]h_{o} = 1024\,m[/tex]

Step-by-step explanation:

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Let [tex](x_1,y_1)[/tex] = (-4, 2)

Let [tex](x_2,y_2)[/tex] = (2, -6)

Substituting given points into the formula:

Answer:

all real numbers.

Step-by-step explanation:

9x - 8y = 1

18x - 16y = 2

if you look at the first equation, you can figure out what y equals.

9x - 8y = 1

add 8y to both sides

9x = 1 + 8y

subtract 1 from both sides

9x - 1 = 8y

divide both sides by 8

[tex]\frac{9x - 1}{8}[/tex] = y

now, substitute y in the second equation.

18x - 16y = 2

18x - 16([tex]\frac{9x - 1}{8}[/tex]) = 2

18x - 2(9x - 1) = 2

18x - 18x +2 = 2

2 = 2

the answer is all real numbers, because regardless of what x equals, 2 will always equal 2.

Step-by-step explanation:

Using translation concepts, it is found that a 90º clockwise rotation of the triangle around the origin took place.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, considering the points on triangles ABC and A'B'C', the change is modeled by:

(x,y) -> (y, -x).

Step-by-step explanation:

The fraction will represent the number of shaded squares over the total number of squares. You have correctly identified it as 98/100. That fraction can be reduced, if you like, to 49/50.

The pronunciation of your fraction is "ninety-eight hundredths." The decimal number with that same pronunciation is 0.98.

The symbol % and the symbol /100 have identical meaning. This makes them essentially interchangeable.

  98/100 = 98%

Your numbers are ...

  98/100 (or 49/50), 0.98, and 98%.

We have shown you that % is a shorthand way to write /100. There is another similar symbol: ‰ is shorthand for /1000.

1/100 is one percent. 1/1000 is one mil.

Answer:

Length = 8

Breadth = 12

Step-by-step explanation:

Since Area = length * breadth

96 = (x+2)(x-2)

Since (a+b)(a-b) = a^2-b^2

(x+2)(x-2) = x^2-4

Therefore

x^2-4 = 96

x^2 = 100

x = +-10

Since x > 0

x = 10

Answer:

  18 weeks

Step-by-step explanation:

We are given the (time, population) pairs (0, 5) and (7, 47). With these values, we can use the two-point form of the equation of a line to write the equation of the linear model.

  p = (p2 -p1)/(t2 -t1)(t -t1) +p1

  p = (47 -5)/(7 -0)(t -0) +5

  p = 6t +5 . . . . . the linear model matching the given points.

For p = 113, the time (number of weeks) is ...

  113 = 6t +5

  108 = 6t . . . . . . subtract 5

  18 = t . . . . . . . . . divide by 6

After 18 weeks, the beetle population will reach 113.

80 >= -8(w-8)

Use distributive property:

80 >= -8w + 64

Subtract 64 from both sides:

16 >= -8w

Divide both sides by -8:

-2 >= w

Because the division was done using a negative value the inequality gets reversed:

w >= -2

Answer:

1664 cards

Step-by-step explanation:

416 divided by 8 is 52 and 52 times 32 is 1664.

(a) Since u = cos(x) gives du = -sin(x) dx, we have

∫ sin(x) cos(x) dx = - ∫ (-sin(x)) cos(x) dx

= - ∫ cos(x) d(cos(x))

= - ∫ u du

= - 1/2 u² + C

= -1/2 cos²(x) + C

(b) Now u = sin(x) gives du = cos(x) dx, so

∫ sin(x) cos(x) dx = ∫ sin(x) d(sin(x))

= ∫ u du

= 1/2 u² + C

= 1/2 sin²(x) + C

(c) Since sin(2x) = 2 sin(x) cos(x), we have

∫ sin(x) cos(x) dx = 1/2 ∫ sin(2x) dx

Substitute u = 2x, so that du = 2 dx, and

∫ sin(x) cos(x) dx = 1/2 ∫ sin(2x) dx

= 1/4 ∫ 2 sin(2x) dx

= 1/4 ∫ sin(u) du

= -1/4 cos(u) + C

= -1/4 cos(2x) + C

(d) Integrate by parts, setting

u = sin(x)          ==>  du = cos(x) dx

dv = cos(x) dx  ==>  v = sin(x)

Then

∫ sin(x) cos(x) dx = sin²(x) - ∫ sin(x) cos(x) dx

2 ∫ sin(x) cos(x) dx = sin²(x) + C

∫ sin(x) cos(x) dx = 1/2 sin²(x) + C

The solutions in (b) and (d) are identical, but all 4 are equivalent, and this follows from the identities,

sin²(x) + cos²(x) = 1

cos(2x) = cos²(x) - sin²(x)

Answer:

y(x) = 1/2 (x - sqrt(5 x^2 + c_1)) or y(x) = 1/2 (x + sqrt(5 x^2 + c_1))

Step-by-step explanation:

Solve 2 x + y(x) + (dy(x))/(dx) (x - 2 y(x)) = 0:

Let P(x, y) = 2 x + y and Q(x, y) = x - 2 y.

This is an exact equation, because (dP(x, y))/(dy) = 1 = (dQ(x, y))/(dx).

Define f(x, y) such that (df(x, y))/(dx) = P(x, y) and (df(x, y))/(dy) = Q(x, y).

Then, the solution will be given by f(x, y) = c_1, where c_1 is an arbitrary constant.

Integrate (df(x, y))/(dx) with respect to x in order to find f(x, y):

f(x, y) = integral(2 x + y) dx = x^2 + x y + g(y) where g(y) is an arbitrary function of y.

Differentiate f(x, y) with respect to y in order to find g(y):

(df(x, y))/(dy) = d/(dy) (x^2 + y x + g(y)) = x + (dg(y))/(dy)

Substitute into (df(x, y))/(dy) = Q(x, y):

x + (dg(y))/(dy) = x - 2 y

Solve for (dg(y))/(dy):

(dg(y))/(dy) = -2 y

Integrate (dg(y))/(dy) with respect to y:

g(y) = integral-2 y dy = -y^2

Substitute g(y) into f(x, y):

f(x, y) = x^2 - y^2 + y x

The solution is f(x, y) = c_1:

x^2 - y^2 + y x = c_1

Solve for y:

y(x) = 1/2 (x - sqrt(5 x^2 - 4 c_1)) or y(x) = 1/2 (x + sqrt(5 x^2 - 4 c_1))

Simplify the arbitrary constants:

Answer:  y(x) = 1/2 (x - sqrt(5 x^2 + c_1)) or y(x) = 1/2 (x + sqrt(5 x^2 + c_1))
