Answer:

[tex]3r^{4}s^{5}\\-r^{4}s^{6}[/tex]

Step-by-step explanation:

The standard form of a polynomial is when its term of highest degree is at first place.

In this case, we have two variables. The grade of each term is formed by the sum of its exponents. That means both given terms have a degree of six. So, the right answers must have a higher degree.

Therefore, the right answers are the second and third choice, because their degrees are 9 and 10 respectively.

Answer:

60 nickles and 30 dimes

Step-by-step explanation:

60 $0.05=3.00

30 $.10=3.00

60+30=90

In the box, there are 30 dimes and 60 nickels, as determined by solving a system of equations based on the total number of coins and their value.

The box contains both dimes and nickels, totaling an amount of money of $6.00. Because a dime is worth $0.10 and a nickel is worth $0.05, we can set up a system of equations to solve this problem.

Let's denote the number of dimes as x and the number of nickels as y. Thus, our equations are x + y = 90 (since the total number of coins is 90) and 0.10x + 0.05y = 6 (since the total value of the coins is $6.00).

Solving these equations will give us the number of dimes and nickels in the box. Doubling the second equation gives us 0.20x + 0.10y = 12. We can subtract the first equation from this to solve for x, giving us x = 30. Substituting x=30 into the first equation, y = 90 - 30, so y = 60. So, there are 30 dimes and 60 nickels in the box.

Answer:

Part A)

[tex]P=\$8,500\\ r=0.052\\n=4[/tex]  

Part B) [tex]S(7)=\$12,203.47[/tex]  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

[tex]S(t)=P(1+\frac{r}{n})^{nt}[/tex]  

where  

S is the Future Value  

P is the Present Value  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

Part A)

in this problem we have  

[tex]P=\$8,500\\ r=5.2\%=5.2/100=0.052\\n=4[/tex]  

Part B) How much money will Marcus have in the account in 7 years?

we have

[tex]t=7\ years\\ P=\$8,500\\ r=0.052\\n=4[/tex]  

substitute in the formula above  

[tex]S(7)=8,500(1+\frac{0.052}{4})^{4*7}[/tex]  

[tex]S(7)=8,500(1.013)^{28}[/tex]  

[tex]S(7)=\$12,203.47[/tex]  

In this problem, we find that Marcus should use the values P = $8,500, r = 0.052 and n = 4 for the given savings account. After calculating, we conclude that Marcus would have approximately $11,713.69 in the account after 7 years.

This problem involves the concept of compound interest in mathematics. Let's break it down:

We use the formula S(t)=P(1+rn)^(nt):

S(7) = 8500(1 + 0.052/4)^(4*7)

By calculating the above, we find the balance after seven years to be approximately $11,713.69 when rounded to the nearest penny.

Answer:

1980.

Step-by-step explanation:

John was born in  1995 - 40 = 1955.

His father was born in 1995 - 65 = 1930.

Let x  be Johns age and his father 2x

1955 + x = 1930 + 2x

1955 - 1930 = 2x - x

x =  25

So the year is 1955 + 25 = 1980..

In that year John was 25 and his father was  50.

Answer:

385.5 USD

Step-by-step explanation:

If an average car is sold for 25,700 USD, and the sales person gets 1.5% commission of it, we can easily get to the amount of money that the sales person managed to get from each sale.

The 25,700 should be divided by 100, as that is number of total percentage:

25,700 / 100 = 257

So we have 1% being 257 USD, but we need 1.5%, so we should multiple the 257 USD by 1.5%:

257 x 1.5 = 385.5

So we get a result of 385.5 USD, which is the amount the sales person makes from commissions on average per sold car.

Answer:

[tex]f^{-1}(x)=-2x+6[/tex].

Step-by-step explanation:

[tex]y=f(x)[/tex]

[tex]y=3-\frac{1}{2}x[/tex]

The biggest thing about finding the inverse is swapping x and y.  The inverse comes from switching all the points on the graph of the original.  So a point (x,y) on the original becomes (y,x) on the original's inverse.

Sway x and y in:

[tex]y=3-\frac{1}{2}x[/tex]

[tex]x=3-\frac{1}{2}y[/tex]

Now we want to remake y the subject (that is solve for y):

Subtract 3 on both sides:

[tex]x-3=-\frac{1}{2}y[/tex]

Multiply both sides by -2:

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

We could leave as this or we could distribute:

[tex]-2x+6=y[/tex]

The inverse equations is [tex]y=-2x+6[/tex].

Now some people rename this [tex]f^{-1}[/tex] or just call it another name like [tex]g[/tex].

[tex]f^{-1}(x)=-2x+6[/tex].

Let's verify this is the inverse.

If they are inverses then you will have that:

[tex]f(f^{-1}(x))=x \text{ and } f^{-1}(f(x))=x[/tex]

Let's try the first:

[tex]f(f^{-1}(x))[/tex]

[tex]f(-2x+6)[/tex]  (Replace inverse f with -2x+6 since we had [tex]f^{-1})(x)=-2x+6[/tex]

[tex]3-\frac{1}{2}(-2x+6)[/tex]  (Replace old output, x, in f with new input, -2x+6)

[tex]3+x-3[/tex]  (I distributed)

[tex]x[/tex]

Bingo!

Let's try the other way.

[tex]f^{-1}(f(x))[/tex]

[tex]f^{-1}(3-\frac{1}{2}x)[/tex] (Replace f(x) with 3-(1/2)x since [tex]f(x)=3-\frac{1}{2}x[/tex])

[tex]-2(3-\frac{1}{2}x)+6[/tex] (Replace old input, x, in -2x+6 with 3-(1/2)x since [tex]f(x)=3-\frac{1}{2}x[/tex])

[tex]-6+x+6[/tex] (I distributed)

[tex]x[/tex]

So both ways we got x.

We have confirmed what we found is the inverse of the original function.

Scale-  Real : Map

          10 yard : 1 cm

        150 yard : 15 cm

        145 yard : 14.5 cm

Step 1: Draw a 7.5 cm line from origin to Point A

Step 2: Form a 2 degree angle from the origin

Step 3: Draw a 7.25 cm line 2 degree angle from the origin to Point B

Step 4: Measure the distance in cm from Point A to Point B

Step 5: Convert the distance from Point A to Point B in yards.

Therefore, the ball is 8 yards far from the goal.

!!

Answer:

The ball is 7.176 yards away from the center of the goal.

Step-by-step explanation:

Given distance between the center goal and Mark is AB = 150 yards

Distance traveled by ball at angle 2 degree off to the right from Mark is

AC = 145 yards

We have to find the distance BC in triangle ABC

Using cosine rule

[tex]BC^{2}=AB^{2}+AC^{2}-2AB\times AC\times \cos \Theta[/tex]

=>[tex]BC^{2}=[150^{2}+145^{2}-2\times 150\times 145\times \cos (2^{\circ})] yards^{2}[/tex]

=>BC^{2}=51.5 yards^{2}

=>[tex]BC=\sqrt{(51.5 yards^{2})}=7.176yards[/tex]

Thus the ball is 7.176 yards away from the center of the goal.

f(8) = 8.25(1.1)^7; f(8) = 16.077

Step-by-step explanation:

In order to calculate the explicit formula we need to look at the y coordinates. All the options list the formula of a Geometric Sequence, so we will find which sequence defines the given coordinates:

The sequence is:

8.25, 9.075, 9.9825, 10.98075

f(1) = First term of the Sequence = 8.25

r = Common Ratio = Ratio of two consecutive terms = [tex]\frac{9.075}{8.25}[/tex] = 1.1

The explicit formula for a geometric sequence is:

[tex]f(n)=f(1)(r)^{n-1}[/tex]

Using the values, we get:

[tex]f(n)=8.25(1.1)^{n-1}[/tex]

For 8th term, we have to replace n by 8:

[tex]f(8)=8.25(1.1)^{8-1}\\\\ f(8)=8.25(1.1)^{7} \\\\ f(8)=16.077[/tex]

So, second option gives the correct answer: f(8) = 8.25(1.1)^7; f(8) = 16.077

step 1

Find CG

we know that

CF=CG

so

CF=7 cm

therefore

CG=7 cm

step 2

Find AG

we know that

CA=AG+CG

we have

CA=15 cm

CG=7 cm

substitute

15=AG+7

AG=15-7=8 cm

step 3

Find AH

Remember that

AG=AH

we have

AG=8 cm

therefore

AH=8 cm

step 4

Find BF

Remember that

BF=BH

BH=3 cm

therefore

BF=3 cm

step 5

Find the perimeter of the triangle

P=AH+BH+BF+CF+CG+AG

substitute the values

P=8+3+3+7+7+8=36 cm

The perimeter of  ΔBCA (triangle BCA) is 36 cm

The perimeter of a triangle is the sum of the length of the three sides.

The inscribed circle contained in the triangle BCA is tangent to the three sides

Therefore,

BF = BH = 3 cm

CF = CG = 7 cm

AH = AG = 15 - 7 = 8 cm

Therefore,

perimeter = CA + BC + BA

perimeter = 15 + 3 + 7 + 3 + 8

Therefore,

perimeter = 15 + 10 + 11

perimeter = 15 + 21

If the equation was y=x^2-8, it would have been down 8 units.

Answer:

Equation of the parabola: [tex]y = 2x^{2} + 4x - 3[/tex].

Axis of symmetry: [tex]x= -1[/tex].

Coordinates of the vertex: [tex]\displaystyle \left(-1, -5\right)[/tex].

Step-by-step explanation:

The axis of symmetry and the coordinates of the vertex of a parabola can be read directly from its equation in vertex form.

[tex]y = a(x-h)^{2} +k[/tex].

The vertex of this parabola will be at [tex](h, k)[/tex]. The axis of symmetry will be [tex]x = h[/tex].

The equation in this question is in standard form. It will take some extra steps to find the vertex form of this equation before its vertex and axis of symmetry can be found. To find the vertex form, find its coefficients [tex]a[/tex], [tex]h[/tex], and[tex]k[/tex].

Expand the square in the vertex form using the binomial theorem.

[tex]y = a(x-h)^{2} +k[/tex].

[tex]y = a(x^{2} - 2hx + h^{2}) +k[/tex].

By the distributive property of multiplication,

[tex]y = (ax^{2} - 2ahx + ah^{2}) +k[/tex].

Collect the constant terms:

[tex]y = ax^{2} - 2ahx + (ah^{2} +k)[/tex].

The coefficients in front of powers of [tex]x[/tex] shall be the same in the two forms. For example, the coefficient of [tex]x^{2}[/tex] in the given equation is [tex]2[/tex]. The coefficient of [tex]x^{2}[/tex] in the equation [tex]y = ax^{2} - 2ahx + (ah^{2} +k)[/tex] is [tex]a[/tex]. The two coefficients need to be equal for the two equations to be equivalent. As a result, [tex]a = 2[/tex].

Similarly, for the term [tex]x[/tex]:

[tex]-2ah = 4[/tex].

[tex]\displaystyle h = -\frac{2}{a} = -1[/tex].

So is the case for the constant term:

[tex]ah^{2} + k = -3[/tex].

[tex]k = -3 - ah^{2} = -5[/tex].

The vertex form of this parabola will thus be:

[tex]y = 2(x -(-1))^{2} + (-5)[/tex].

The vertex of this parabola is at [tex](-1, -5)[/tex].

The axis of symmetry of a parabola is a vertical line that goes through its vertex. For this parabola, the axis of symmetry is the line [tex]x = -1[/tex].
