Can someone help me on this plzzz???

Answer:

Step-by-step explanation:

Scale factor  = 1 : 7

a)Let the length of the house in the scale drawing = x

1:7 :: x : 21

Product of means = Product of extremes

 7*x = 1* 21

     x = [tex]\frac{1*21}{7}[/tex]

     x = 3

Length of the house in the scale drawing = 3 in

b) Height of the real house =y

1 : 7 :: 4 : y

Product of extremes = product of means

1 * y = 7*4

   y = 7*4

   y = 28

Height of real house = 28 feet

Answer:

Mode and mean

Step-by-step explanation:

The measure of central tendency that can be determined by just looking at the  box plot is : MEDIAN but the other measures of central tendencies. that cannot be determined  accurately by just looking at the box plot . are MODE  and MEAN

This simply because of how a box plot is created ( it makes it easier to determine the median value other than other central tendencies )

Step-by-step explanation:

hello : solutions in R

cosxcos((x+π)/4) =0

means :   cosx = 0   or   cos((x+π)/4) =0

1)   cosx = 0    means : x = π/2+kπ    k in Z

2)  cos((x+π)/4) =0  means :  (x+π)/4 =  π/2+kπ .......continu calculate : x

Answer:

f(x) = (x + 1)(x + 2)

Step-by-step explanation:

Zero x = -1 corresponds to factor x + 1, and zero x = -2 to x + 2.  Thus, the quadratic in question is

f(x) = (x + 1)(x + 2)

Answer:

Cash price

Step-by-step explanation:

The computation is shown below:

The Interest rate per month (r) = (9% ÷ 12) = 0.75%

Now Present value of the monthly payment is

= PMT × {[(1 + rate of interest)^number of years - 1] ÷ rate of interest}

= 1,499 × {[(1 + 0.75%)^12 - 1] ÷ 0.75%}

= 18,748.89

And the cash price is 15,999

So, the cash price would be lower

The cash price would be lower. A further explanation is below.

According to the question,

Interest rate per month,

[tex]r = \frac{9 \ percent}{12}[/tex]

  [tex]= 0.75[/tex] (%)

hence,

The Present value of the monthly payment will be:

= [tex]PMT\times \frac{{(1 + Interest \ rate)^{number \ of \ years} - 1}}{Interest \ rate}[/tex]  

= [tex]1499\times \frac{[(1 + 0.75 \ percent)^{12} - 1] }{0.75 \ percent}[/tex]  

= [tex]18748.89[/tex]

As we can see that the cash price is 15,999. Thus the above answer is right.

Answer:

-1-2-4-8-16

Step-by-step explanation

The solution is, 1-2 + 4-8 + 16, is the correct expanded form for the series Σ-2^n, n = 0 to 4.

An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.

here, we have,

given that,

the  series Σ-2^n, n = 0 to 4.

now, we have to find,

the correct expanded form for the series ,

as , we get,

the value of n = 0 to 4

so, putting the value of n = 0,1,2,3,4

we get the series as,

Σ-2^n

= -2^0 + (-2)^1 + (-2)^2 + (-2)^3 + (-2)^4

= 1 -2 + 4 - 8 +16

Hence, The solution is, 1-2 + 4-8 + 16, is the correct expanded form for the series Σ-2^n, n = 0 to 4.

Step-by-step explanation:

How do you classify a triangle by its angle?

An acute triangle has three angles that each measure less than 90 degrees. An equilateral triangle is a triangle in which all three sides are the same length. An obtuse triangle is a triangle with one angle that is greater than 90 degrees. A right triangle is a triangle with one 90 degree angle.

Answer:

B 17.5 ft

Step-by-step explanation:

tangent = opposite / adjacent

tan 35° = h / 25

multiply both sides by 25

h = 25 (tan 35°)

tan 35° = 0.70 (from your calculator)

h = 25 (0.70)

h = 17.51 ft.

Answer:

2⁴/4² = 1

2 × 3¹ = 6

(4-2)² = 4

Answer:

1. Correct

2. Correct again

3. 4

Step-by-step explanation:

The first one is correct If you need an explanation let me know.

Second one is the same

For the third one since 4-2 is in () you would have to do it first

4-2= 2

Then you will have to do it to the 2nd power which would mean...

2 x 2= 4

So 4 would be your answer.
