refer to the right triangle ABC below. Identify the correct values for B and C​

Answer:c

Step-by-step explanation:

Bc if it’s a square there will be 4 corners and each will have the same number count so u have to put even numbers in each corner and that’s 25 25+25=50 25+25=50 50+50=100

Given:

[tex]a_1=-4[/tex] and [tex]a_n=a_{n-1}+9[/tex] where [tex]n\geq 2[/tex].

To find:

The explicit formula for the given recursive formula.

Solution:

We know that recursive formula of an AP is:

[tex]a_n=a_{n-1}+d[/tex]

Where, d is the common difference.

We have,

[tex]a_n=a_{n-1}+9[/tex]

Here, d=9.

The first term of the AP is [tex]a_1=-4[/tex].

The explicit formula for an AP is:

[tex]a_n=a_1+(n-1)d[/tex]

Substituting [tex]a_1=-4[/tex] and [tex]d=9[/tex], we get

[tex]a_n=-4+(n-1)9[/tex]

[tex]a_n=-4+9n-9[/tex]

[tex]a_n=-13+9n[/tex]

Therefore, the required explicit formula for the given sequence is [tex]a_n=-13+9n[/tex].

1) To get the present value, we need to get the amount after 5.5years

Amount = Principal + Interest

Interest = PRT/100

Interest = $19,513.75*3*5.5/100

Interest = 321,976.875/100

Interest =  $3219.76875

Amount = $19,513.75+$3219.76875

Amount = 22,733.51875

Hence the present value is $22,733.51875

2) Simple Interest = PRT/100

Simple Interest = 5000*(4 3/4)* 18/12*100

Simple interest = 5 * 19 * 18/4*12

Simple interest = 1710/48

Simple interest =35.625

Amount = 5000 + 35.625

Amount = $5035.625

Hence the present value is $5035.625

Answer:

80°+65°+2x+3x=360°(sum of quadrilateral is 360)

145°+5x=360°

5x=360°-145°

5X=215°

X=215°/5°

X=43°

The required value is [tex]x=43[/tex]

Given angles are,

[tex]80^{\circ}, 65^{\circ}, 2x,3x[/tex]

As we know the sum of all angles in the quadrilateral is [tex]360^{\circ}[/tex].

Then we have the relation,

[tex]80+65+2x+3x=360\\\\145+5x=360\\5x=360-145\\5x=215\\x=43[/tex]

So, the value of the x is 43.

Answer:

GH = 20

Step-by-step explanation:

Here, we want to get the numerical length of GH

from what we have, G is on FH

What this could mean is that;

FG + GH = FH

x + 5x = 4x + 8

6x = 4x + 8

6x-4x = 8

2x = 8

x = 8/2

x =4

Recall;

GH = 5x

GH = 5(4)

GH = 20

Answer:

[tex]\boxed {\boxed {\sf x \approx 23.49 \ cm }}[/tex]

Step-by-step explanation:

This is a right triangle (the small square in the corner signifies a 90 degree angle), so Pythagorean Theorem can be used.

[tex]a^{2} + b^{2} =c^{2}[/tex]

where a and b are the legs of the triangle and c is the hypotenuse. In this triangle, 17 and x are the legs because they form the right angle. 29 in the hypotenuse because it is opposite the right angle.

[tex]a= 17 \\b=x \\c= 29[/tex]

[tex]17^{2} + x^{2} =29^{2}[/tex]

Solve the exponents.

[tex]289+x^{2} =841[/tex]

289 is being added to x and the inverse is subtraction. Subtract 289 from both sides to isolate the variable.

[tex]289-289+ x^{2} =841-289\\x^{2} =552[/tex]

x is being squared and the inverse is a square root. Take the square root of both sides of the equation.

[tex]\sqrt {x^{2} }=\sqrt {552}[/tex]

[tex]x=23.4946802489[/tex]

Let's round to the nearest hundredth. The 4 in the thousandth place tells us to leave the 9.

[tex]x \approx 23.49[/tex]

x is approximately 23.49 centimeters.

Answer: A. There are 3 squirrels for every 25 pigeons in the park

Step-by-step explanation:

The options include:

A) There are 3 squirrels for every 25 pigeons in the park.

B) There are 3 squirrels for every 5 pigeons in the park.

C) There are 5 squirrels for every 3 pigeons in the park.

D) There are 25 squirrels for every 3 pigeons in the park.

Since the ratio of squirrels to pigeons in the park is 15 to 125. The common factor we have here is 5. We can then divide the figures given by 5. This will be:

= 15/125 = (15/5)/(125/5) = 3/25

This mean that for every 3 squirrels, there are 25 pigeons in the park.

Therefore, the correct answer is A.

Answer:

x= 25°

Step-by-step explanation:

3x-10 = 25 + x + 15 (ext ∠ of triangle equals to the sum of interior opposite ∠'s)

3x - x = 40 +10

2x= 50

x= 50/2

x= 25°

Answer:

A = $ 50,978.44

Step-by-step explanation:

First, convert R percent to r a decimal

r = R/100

r = 5%/100

r = 0.05 per year,

Then, solve our equation for A

A = P(1 + r/n)nt

A = 45,000.00(1 + 0.004166667/12)(12)(2.5)

A = $ 50,978.44

The fourth graph represents the function  [tex]f(x)=\frac{3}{2} 2^{x}[/tex]

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The given function is [tex]y=\frac{3}{2} 2^{x}[/tex]

It is an exponential function and 2>1, therefore it is an increasing in nature.

put x=0 in the given function to find the y-intercept of the graph.

f(0)=3/2.2⁰

f(0)=3/2(1)

f(0)=3/2=1.5

So, the y-intercept is 1.5.

In figure 1 and figure 1 the y-intercept is 1,  in figure 2 the y-intercept is 2 , therefore first three options are incorrect.

In figure 4 the y-intercept is 1.5, therefore the option 4 is correct.

Hence, the fourth graph represents the function  [tex]f(x)=\frac{3}{2} 2^{x}[/tex]

Answer:

a) Mark's best score on the game is 75 points.

b) Virginia's best score is 15 points.

Step-by-step explanation:

Jodi's best score on a video game is 50 points.

a) Mark's best score on the game is 1.5 times as much as Jodi's best score. How many points did Mark score on the video game?

Mark's best score on the game is calculated as:

1.5 times as much as Jodi.

Jodi's best score = 50 points

= 1.5 × 50 points

= 75 points

b) Virginia's best score is only 0.3 times Jodi's best score. How many points did Virginia score on the game? Virginia's best score is points.

Virginia's best score on the game is calculated as:

0.3 times as much as Jodi.

Jodi's best score = 50 points

= 0.3 × 50 points

= 15 points

Virginia's best score is 15 points.

Answer:

The area of the regular nonagon is 7921.8 square inches.

Step-by-step explanation:

Geometrically speaking, the area of a regular polygon is determined by following area formula:

[tex]A = \frac{p\cdot a}{2}[/tex] (1)

Where:

[tex]A[/tex] - Area of the regular polygon, in square inches.

[tex]p[/tex] - Perimeter, in inches.

[tex]a[/tex] - Apothem, in inches.

If we know that [tex]p = 162\,in[/tex] and [tex]a = 97.8\,in[/tex], then the area of the regular nonagon is:

[tex]A = 7921.8\,in^{2}[/tex]

The area of the regular nonagon is 7921.8 square inches.
