Determine the total SA of this cone having radius 7 inches and a slant height 11 inches.

a) 259.7 in^2
b) 395.8 in^2
c) 153.9 in^2
d) 241.9 in^2 ​

Answer:

Step-by-step explanation:

Let the costs of 1 t - shirt and 1 pair of pants be 'x' and 'y' respectively then:

Case 1 --> 8x + 5y = 220 ----------(1)

Case 2 --> 5x + y = 112 ----------(2)

Multiplying equation (2) by 5:

8x + 5y = 220

25x + 5y = 560 ------(3)

Subtracting equation (1) from equation (3) we get :

17x = 340

x = 20

Putting x in (2):

5 x 20 + y = 112

y = 12

therefore, cost of each t-shirt is 20 rupees and the cost of each pair of pants is 12 rupees

The standard form of the polynomial -n²(n² + 5n + 6) is  -n⁴ - 5n³ - 6n².

Polynomials are algebraic expressions that consist of variables and coefficients.

The standard form of a polynomial is expressed by writing the highest degree of terms first then the next degree and so on.

Hence, let's represent the polynomial in standard form as follows:

-n²(n² + 5n + 6)

Open the brackets

-n²(n² + 5n + 6) = -n⁴ - 5n³ - 6n²

Hence,

-n²(n² + 5n + 6) = -n⁴ - 5n³ - 6n²

Step-by-step explanation:

Given

Scale is 2 cm to 100 km i.e. 2 cm of the map is equivalent to 100 k in the true sense

or 1 cm is equivalent to 50 km

If the distance between the two towns is 2.5 cm

Answer:

  1056

Step-by-step explanation:

You want the product of the LCM and the GCF of 22 and 48.

One way to find the LCM of two numbers is to start with their product, then divide out the extra factor:

  LCM(A, B) = (A×B)/GCF(A, B)

Since we want the product of the LCM and the GCF, we can start with this and multiply by the GCF:

  LCM(A, B) · GCF(A, B) = ((A×B)/GCF(A, B)) · GCF(A, B)

  LCM(A, B) · GCF(A, B) = A×B

Using this for the given numbers, we get ...

  LCM(22, 48)·GCF(22, 48) = 22·48 = 1056

__

Additional comment

If you want to go to the trouble of finding the LCM and GCF, you get ...

  22 = 2·11

  48 = 2·24

  LCM(22, 48) = 2·11·24 = 528

  GCF(22, 48) = 2

  LCM·GCF = 2·528 = 1056

Answer:

  b.  ±√60

Step-by-step explanation:

You want to know the solution to x² = 60.

In general, the process of solving for a variable's value requires you to "undo" what is done to the variable. This generally means you use inverse operations. The inverse of the squaring operation is the square root operation.

Taking the square root of both sides, we get ...

  √(x²) = √60

  |x| = √60 . . . . . . simplify the left side

  x = ±√60 . . . . . . . write the equivalent without the absolute value bars

__

Additional comment

As with any operation performed on an equation, it must be done to both sides of the equal sign.

You will get a ±(radical) result whenever you take an even-index root: square root, fourth root, sixth root, and so on. Odd-index roots will have the same sign as the value under the radical.

Translate(1.3, -1)

Scale Factor: 2/3

Step-by-step explanation:

First, perform a dilation about the origin. This will make the original shape smaller.

From the given diagram, we can see that R'S' is 10 units long. RS is 15 units long. Using this information, we can create this ratio.

[tex]\frac{10}{15}[/tex]

This means that Triangle R'S'T' is 2/3 of Triangle RST. Construct lines from the origin (the center of dilation) to each point on the original triangle. Then, find two thirds of that line. The new point will be the new y-coordinate.

The new coordinates will (approx.) be:

R = (-2, 4.7)

S = (-2, -5.3)

Only two coordinates are necessary to perform this translation. As per the graph, this triangle must shift approximately 1.3 units up and 1 unit to the left. Thus, the final translation is:

Translate(1.3, -1)

Scale Factor: 2/3

Answer:

The equation for this sequence will be 8 + 17n - 17 with n being replaced with the term number you are trying to find.

so 8 + 17(16) - 17

17 x 16= 272

8 + 272= 280

280- 17= 263

Thus, the 16th term will be 263.

Answer:

16ᵗʰ Term of the sequence is 263

Step-by-step explanation:

Here,

First Term = a₁ = 8

Second Term = a₂ = 25

Third Term = a₃ = 42

Now,

Common Difference (d)

d = a₂ - a₁ = 25 - 8 = 17

d = a₃ - a₂ = 42 - 25 = 17

Here, Common Difference is same everywhere

Now, For 16ᵗʰ term, n = 16

aₙ = a + (n - 1)d

a₁₆ = 8 + (16 - 1) × 17

a₁₆ = 8 + 15 × 17

a₁₆ = 8 + 255

a₁₆ = 263

Thus, 16ᵗʰ Term of the sequence is 263

Answer:

Rate = 7.0% per year

Step-by-step explanation:

Formula: rate = In(A/P)/t

I = interest

n = compound, in this case continuous

A = Total amount ($133,000)

P = Principal ($33,000)

t = time (20 years)

Plug in the values and solve:

rate = In(133000/33000)/20

rate = 0.06969

Convert to percentage:

rate = 6.969%

Round to the nearest tenth of a percent:

Answer:

y = 2x + 10

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, 10) ← 2 points on the line

m = [tex]\frac{10-0}{0-(-5)}[/tex] = [tex]\frac{10}{0+5}[/tex] = [tex]\frac{10}{5}[/tex] = 2

the line crosses the y- axis at (0, 10 ) ⇒ c = 10

y = 2x + 10 ← equation of line

The total amount available with Carlos for his holiday to Germany = 515 Euros

Amount spent to obtain these 515 Euros = £ 412

As it is clear that for buying 515 Euros he spent 412 Euros.

So, we will first find the Euros spent on buying 1 Euro.

For that, we will use Unitary Method:

So, the total Euros spent for buying 1 Euro will be = (412/515) = 0.8

So, for finding the total Euros spent for obtaining 500 Euros we will simply multiply the total Euros needed by the Euro spent for buying 1 Euro.

Thar will be equal to (0.8 * 500) = 400 Euros.

The polynomial in intercept form so that P(x)=0 has the given roots is, x^2 - √3x - 2x + 2√3 = 0.

What is polynomial?

A polynomial is an expression in mathematics that only uses the operations of addition, subtraction, multiplication, and powers of positive-integer variables. It consists of indeterminates and coefficients. The polynomial x^2 4x + 7 is an illustration of one with a single indeterminate x.

We have to find the polynomial in intercept form so that P(x)=0 has the roots 2 and √3.

Let 2 and √3 are the roots of the polynomial so,

x = 2,  x = √3

⇒ x - 2 = 0,  x - √3 = 0

⇒ (x - 2)(x - √3) = 0

x^2 - √3x - 2x + 2√3 = 0

Hence, the polynomial in intercept form so that P(x)=0 has the given roots is, x^2 - √3x - 2x + 2√3 = 0.
