Melia get paid $40 for mowing her neighbor' lawn. She pend $16 on a bracelet and $7 on lunch. Which equation i written and olved correctly to how how much money (m) Melia ha left?

Answer:

Since, it is a triangle and the sum of angles of triangle is 180°. So

72+57+X=180

or, 128+X=180

or, X= 180-128

X= 51°

The total number of lattice points for the equation of the line y = -2x + 18 with given condition is equal to 10.

The equation of the line is y = -2x + 18.

To find the lattice points on this line,

find integer solutions for x and y that satisfy this equation.

Substituting y = -2x + 18 into the equation, we get,

-2x + 18 = y

We know that x and y are both non-negative integers,

so start by setting y = 0 and solving for x,

⇒-2x + 18 = 0

⇒-2x = -18

⇒x = 9

So one lattice point on the line is (9, 0).

Now ,substitute this value of x back into the equation to find the corresponding value of y,

y = -2(9) + 18

y = 0

So the lattice point is (9, 0).

Repeat this process by setting y = 1, 2, 3, and so on,

Until we find all the lattice points on the line.

For y = 1, we get,

⇒-2x + 18 = 1

⇒-2x = -17

⇒x = 8.5

But x must be a non-negative integer,

so there are no lattice points for y = 1.

For y = 2,

⇒-2x + 18 = 2

⇒-2x = -16

⇒x = 8

So the lattice point is (8, 2).

For y = 3,

⇒-2x + 18 = 3

⇒-2x = -15

⇒x = 7.5

Again, there are no lattice points for y = 3.

Continue this process until we have checked all possible values of y.

The lattice points on the line are,

(9, 0)

(8, 2)

(7, 4)

(6, 6)

(5, 8)

(4, 10)

(3, 12)

(2, 14)

(1, 16)

(0, 18)

Therefore, there are 10 lattice points on the line y = -2x + 18 that satisfy the conditions x ≥ 0 and y ≥ 0.

Answer:

I Think D.

Step-by-step explanation:

Answer:

A.  Circle.

     \((x+15)^2+(y-0)^2=13^2\)

B.  Parabola.

     \((x-15)^2=-16(y-20)\)

C.  Maximum height of Tunnel A = 13 ft.

     Maximum height of Tunnel B = 20 ft.

     The truck can only pass through Tunnel B without damage.

Step-by-step explanation:

\(\boxed{\begin{minipage}{6.3cm}\underline{General equation for any conic section}\\\\$Ax^2+Bxy+Cy^2+Dx+Ey+F = 0$\\\\where $A, B, C, D, E, F$ are constants.\\\end{minipage}}\)

Circle:  A and C are non-zero and equal, and have the same sign.

Ellipse:  A and C are non-zero and unequal, and have the same sign.

Parabola:  A or C is zero.

Hyperbola:  A and C are non-zero and have different signs.

Tunnel A

\(x^2+y^2+30x+56=0\)

As the coefficients of x² and y² are non-zero, equal and have the same sign, the conic section is a circle.

\(\boxed{\begin{minipage}{4 cm}\underline{Equation of a circle}\\\\$(x-h)^2+(y-k)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(h, k)$ is the center. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}\)

Rewrite the given equation for Tunnel A in the standard form of the equation of a circle:

\(\implies x^2+y^2+30x+56=0\)

\(\implies x^2+30x+y^2-56\)

\(\implies x^2+30x+\left(\dfrac{30}{2}\right)^2+y^2=-56+\left(\dfrac{30}{2}\right)^2\)

\(\implies x^2+30x+225+y^2=-56+225\)

\(\implies (x+15)^2+(y-0)^2=169\)

\(\implies (x+15)^2+(y-0)^2=13^2\)

Therefore, the center of the circle is (-15, 0) and the radius is 13.

Tunnel B

\(x^2-30x+16y-95=0\)

There is no term in y² so the coefficient of y² is zero.  Therefore, the conic section is a parabola.

\(\boxed{\begin{minipage}{5.5 cm}\underline{Standard form of a parabola}\\(with a vertical axis of symmetry)\\\\$(x-h)^2=4p(y-k)$\\\\where:\\ \phantom{ww}$\bullet$ $p\neq 0$. \\ \phantom{ww}$\bullet$ $(h,k)$ is the vertex.\\\end{minipage}}\)

Rewrite the given equation for Tunnel B in the standard form a parabola:

\(\implies x^2-30x+16y-95=0\)

\(\implies x^2-30x=-16y+95\)

\(\implies x^2-30x+\left(\dfrac{30}{2}\right)^2=-16y+95+\left(\dfrac{30}{2}\right)^2\)

\(\implies x^2-30x+225=-16y+95+225\)

\(\implies (x-15)^2=-16(y-20)\)

Therefore, the vertex is (15, 20).

Maximum height of Tunnel A

The maximum point of a circle is the sum of the y-value of its center and its radius:

Maximum height of Tunnel B

The maximum point of a downwards opening parabola is the y-value of its vertex:

As the truck is 13.5 feet high, it cannot pass through Tunnel A since the maximum height of Tunnel A is 13 feet.

The maximum height of Tunnel B is certainly adequate for the truck to pass through.  However, to determine if the truck can pass through Tunnel B safely, we also need to find the width of the tunnel when its height is 13.5 feet.  To do this, find the x-values of the parabola when y = 13.5.  If the difference in x-values is 8 or more, then the truck can pass through safely.

Substitute y = 13.5 into the equation for Tunnel B and solve for x:

\(\implies (x-15)^2=-16(13.5-20)\)

\(\implies (x-15)^2=-16(-6.5)\)

\(\implies (x-15)^2=104\)

\(\implies \sqrt{(x-15)^2}=\sqrt{104}\)

\(\implies x-15=\pm\sqrt{104}\)

\(\implies x=15\pm\sqrt{104}\)

Now find the difference between the two found values of x:

\(\implies (15+\sqrt{104})-(15-\sqrt{104})\)

\(\implies 15+\sqrt{104}-15+\sqrt{104}\)

\(\implies 2\sqrt{104}\)

\(\implies 20.39607...\)

Therefore, as the width of Tunnel B is 20.4 ft when its height is 13.5 ft, the 8 ft wide truck can easily pass through without damage since 20.4 ft is greater than the width of the truck.

Answer: 2x2−3x−8

Step-by-step explanation:

By using a maclaurin series to obtain the maclaurin series for the given function is  F(x) = x cos(5x) = \(1 - 25x^2/2! + 625x^4/4! - 15625x^6/6! + ...\)

To obtain the Maclaurin series for the function f(x) = x cos(5x), we need to write the Maclaurin series for cos(5x). The Maclaurin series for cos(x) is: \(cos(x) = 1 - x^2/2! + x^4/4! - x^6/6! + ...\)

Using this formula, we can substitute 5x for x and obtain the Maclaurin series for cos(5x): cos(5x) =\(1 - (5x)^2/2! + (5x)^4/4! - (5x)^6/6! + ...\)

\(= 1 - 25x^2/2! + 625x^4/4! - 15625x^6/6! + ...\)

We can substitute this series into the original function f(x) = x cos(5x) and obtain its Maclaurin series: f(x) = x cos(5x)

\(= x[1 - 25x^2/2! + 625x^4/4! - 15625x^6/6! + ...]\)

\(= x - 25x^3/2! + 625x^5/4! - 15625x^7/6! + ...\)

This is the Maclaurin series for the function f(x) = x cos(5x). It is obtained by substituting the Maclaurin series for cos(5x) into the original function and simplifying the resulting series. Maclaurin series are useful for approximating functions using polynomials. By truncating the series after a certain number of terms, we can obtain a polynomial that approximates the original function to a certain degree of accuracy. The accuracy of the approximation depends on the number of terms in the series that are used. The more terms we include, the more accurate the approximation will be.

- A way you can answer is to do 180 - 47  which is 133

- Do 180 - 133 = 47.

-So Basically The answer is the opposite (In Simple Terms)

The simplified expressions are (2a + 2b + 4)^2, (5 + 2x + y + 2z)^2, (3 + z)^2 (2p + q - 1)^3 and (5+q)^3

The distributive property states that:

a^x * b^x = (ab)^x

So, we have:

(a+b)^2 (a+1)^2 (3+b)^2

(a+b)^2 (a+1)^2 (3+b)^2 = (a + b + a + 1 + 3 + b)^2

Evaluate the like terms

The  area of the rectangle is:

Area = length x width
Area = 39 km x (x-3) km
Area = 39(x-3) km²

To find the area of the rectangle, we need to multiply its length by its width.

The length of the rectangle is given as 39 kilometers.

The width of the rectangle is given as (x-3) kilometers.

So the area of the rectangle is:

Area = length x width
Area = 39 km x (x-3) km
Area = 39(x-3) km²

This is the final answer for the area of the rectangle in terms of x.

It's worth noting that we can simplify this expression by multiplying out the brackets:

Area = 39(x-3) km²
Area = 39x km² - 117 km²

This gives us a simpler expression for the area of the rectangle, but it's important to remember that this expression is only valid if x represents a length that is greater than 3 kilometers. If x is less than or equal to 3 kilometers, then the width of the rectangle would be negative, which doesn't make sense.

Answer:

Option A

Step-by-step explanation:

From the graph attached,

Distance of point A of rectangle ABCD = 5 units

Distance of point E of rectangle EFGH = 5 units

Similarly, all the vertices of the rectangles ABCD and EFGH are equidistant from the y-axis.

Therefore, rectangle ABCD and rectangle EFGH may overlap each other by reflecting each other across y-axis.

Let's check by the rule of reflection,

Rule for the reflection of a point (x, y) across y-axis is given by,

(x, y) → (-x, y)
