ANSWER

The area of the triangle is 6.64 square feet.

EXPLANATION

The area of the given triangle is calculated using the formula

[tex]Area = \frac{1}{2} ab \sin(C)[/tex]

where C=62° is the included angle.

a=4.7 ft and b=3.2 ft.

We plug in the values into the formula to get:

[tex]Area = \frac{1}{2} \times 4.7 \times 3.2\sin(62 \degree)[/tex]

Area=6.64 ft² to the nearest hundredth.

Answer:

[tex]\$164.62[/tex]

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

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

case A) compounded monthly

in this problem we have  

[tex]t=25\ years\\ P=\$5,000\\ r=0.06\\n=12[/tex]  

substitute in the formula above  

[tex]A=\$5,000(1+\frac{0.06}{12})^{12*25}=\$22,324.85[/tex]  

case B) compounded quarterly

in this problem we have  

[tex]t=25\ years\\ P=\$5,000\\ r=0.06\\n=4[/tex]  

substitute in the formula above  

[tex]A=\$5,000(1+\frac{0.06}{4})^{4*25}=\$22,160.23[/tex]  

Find the difference

[tex]\$22,324.85-\$22,160.23=\$164.62[/tex]

Step-by-step explanation:

The rule for condensing (combining) log expressions that are added is MULTIPLICATION

log₄12 + log₄7 = log₄(12 × 7) = log₄ 84

Answer:

A

Step-by-step explanation:

Given sinP = [tex]\frac{5}{13}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]

Then the right triangle has a hypotenuse of 13 and a leg 5

Use Pythagoras' identity to find the other leg x ( adjacent)

x² + 5² = 13²

x² + 25 = 169 ( subtract 25 from both sides )

x² = 144 ( take the square root of both sides )

x = [tex]\sqrt{144}[/tex] = 12 , hence

tanP = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{5}{12}[/tex]

The value of the tanP when sin is equal to 5/13  is 5/12.

We have given that,

[tex]sinP = \frac{5}{13}[/tex]

[tex]sin(\theta)=\frac{Opposite}{hypogenous}[/tex]

Then the right triangle has a hypotenuse of 13 and a leg of 5

Use Pythagoras' identity to find the other leg x ( adjacent)

x² + 5² = 13²

x² + 25 = 169 ( subtract 25 from both sides )

x² = 144 ( take the square root of both sides )

taking square root on both sides

[tex]x=\sqrt{144} \\x=12[/tex]

Therefore we get the value of the tanP.

[tex]tanP = \frac{opposite }{adjucent} = \frac{5}{12}[/tex]

Therefore the value of the tanP is 5/12.

Step-by-step explanation:

(1,1) and (2,4)

Slope = (4 - 1)/(2-1) = 3, y- intercept b = -2

Equation

y = 3x - 2

Answer:

Y = 3x - 2 will be the answer.

Step-by-step explanation:

A line has been graphed in the figure attached.

It passes through two points ( 1,1) and (2,4)

Y-intercept of the given line is (-2)

Since equation of a line in the intercept form is

y = mx + c

where m = slope and c = y-intercept

and slope m =  [tex]\frac{y-y'}{x-x'}[/tex]

Therefore, slope m =  [tex]\frac{4-1}{2-1}[/tex]

                                =  [tex]\frac{3}{1}[/tex]

Therefore, equation of the given line will be y = 3x - 2

Answer:

D. X=1.75

Step-by-step explanation:

To start, let’s divide both sides by 4.

So 3^x =27.48/4

Since we want to solve for x, we take the log_3 of both sides.

So [tex]log_{3}3^x[/tex]=[tex]log_{3}6.87[/tex]

Using the laws of logs, we get

[tex]x*log_{3}3[/tex]=[tex]log_{3}6.87[/tex]

since [tex]log_{3}3[/tex] is 1, we get

X=[tex]log_{3}6.87[/tex]

Using a calculator, we find that x is about 1.75

Answer:

25.5°, 25.5°, 129° and 51°, 64.5°, 64.5°

Step-by-step explanation:

if you read the problem carefully you will notice that there are actually 2 ways of solving this problem. the first is by looking at the arc as if it is across from angle A, while the second is so the arc is across from side BC and bisected by point A (because the triangle is isosceles).

first way:

102/2=51°=m∠A

180-51=129°=m∠B+m∠C

129/2=m∠B=m∠C=64.5°

answers: 64.5°, 64.5°, 51°

second way:

102/2=51

51/2=m∠B=m∠C=25.5°

180-51=129°=m∠A

answers: 25.5°, 25.5°, 129°

The central angle BOC is twice the measure of arc BC, so it is 204°. Since the circle is 360°, the sum of the other two angles is 156°. Being an isosceles triangle, angles ABC and ACB are equal, thus each is 78°.

To find the measure of the angles of an isosceles triangle ABC inscribed in a circle, with the measure of arc BC being 102°, we utilize the properties of a circle and the fact that an isosceles triangle has two equal angles. In a circle, the angle subtended by an arc at the center is twice the angle subtended on the circumference. Thus, if the measure of arc BC is 102°, the central angle BOC would be 204° (since it's twice the angle at the circumference).

This central angle separates the circle into two segments, one of which is the base of the isosceles triangle. The other two angles of the triangle, angles A and ABC or ACB (since it's an isosceles triangle, these angles are equal), will each occupy the remaining portion of the circle that amounts to 360° - 204° = 156°. Since the angles at B and C are equal in an isosceles triangle, we divide the remaining 156° by 2 to find each angle. Therefore, angle A = 204°, and each of the other two angles is 78°.

i tried working this out but it doesnt make sense, at least the table doesnt... did you make this question up or get it off of a school assignment??

Answer: Option A; 19

Step-by-step explanation:

The data is:

We have 40 students.

16 play football

9 play basketball

4 play bot sports.

We want to find the number of students that do not play either sport, for this we should add the number of students that play football and the number of students that play basketball, subtracting the number of students that play both sports (because we sill be counting those two times, this is because those 4 students are included in the 16 for football and also in the 9 for basketball.)

N = 16 + 9 - 4 = 12 + 9 = 21

the number of students that do not play basket or football is equal to:

40 - N = 40 - 21 = 19

The correct option is A

Answer:

Step-by-step explanation:

when the two angles are added they are equal to 180 degree. (corresponding angles property)

x+8+3X+2=180

4X+10=180

4X=170

X=44.25 DEGREES

Question 1:

For this case we have that by definition, if a and b are two parallel lines, then the corresponding angles are congruent, that is, we can write 3x + 2 and x + 8 as supplementary angles:

[tex](3x + 2) + (x + 8) = 180\\3x + 2 + x + 8 = 180\\4x + 10 = 180\\4x = 180-10\\4x = 170\\x = \frac {170} {4}\\x = 42.5[/tex]

We look for the value of the angles:

[tex]3 (42.5) + 2 = 129.5\ degrees\\42.5 + 8 = 50.5 \ degrees[/tex]

ANswer:

[tex]x = 42.5\\3 (42.5) + 2 = 129.5\ degrees\\42.5 + 8 = 50.5 \ degrees[/tex]

Question 2:

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cutoff point with the y axis

Now, in the equation [tex]y = 2x + 3[/tex]

[tex]m = 2\\b = 3[/tex]

By definition, if two lines are parallel, their slopes are equal. Also, if two lines are perpendicular, then the product of their slopes is -1.

So:

The slope of a line parallel to the given line is:

[tex]m = 3[/tex]

The slope of a line perpendicular to the given line is:

[tex]3 * m = -1\\m = - \frac {1} {3}[/tex]

ANswer:

Step-by-step explanation:

Mean absolute deviation is the average distance between the data points from the set to the mean point of the data set. It shows the variability in data or how much the data points are spread.

method to calculate Mean absolute deviation:

a. calculate mean

b. calculate absolute deviation of each data point

c. add all the deviations

d. divide absolute deviation by number of points

mean absolute deviation = ∑l[tex]x_{i}[/tex]-xl / n

The given problem has four sub-parts

Solution 1:

Mean= (78+99+90+80+55+56+102+88+60+42)/10

            =  750/10

            =  75

Mean absolute deviation= ( I 78-75 I + I 99-75 I+I 90-75 I + I 80-75 I +

                                             I 55-75 I + I 56-75 I + I 102-75 I + I 88- 75 I +

                                             I 60-75 I + I 42-75 I) /10

         =  (174)/10

        =  17.4

Solution 2:

Mean = (10+13+7+12+9+8+12+10+11+13)/10

              =  (105)/10

              = 10.5

Mean absolute deviation = ( I 10-10.5 I + I 13-10.5 I + I 7-10.5 I + I 12-10.5 I +

                                              I 9-10.5 I + I 8-10.5 I + I 12-10.5 I + I 10-10.5 I +

                                               I 11-10.5 I + I 3-10.5 I) /10

       =   17/10

       = 1.7

Solution 3:

Mean= (1+7+10+5+3+3+6+12+9+4)/10

            =  60/10

            =  6

Mean absolute deviation  = ( I 1-6 I + I 7-6 I + I 10-6 I + I 5-6 I + I 3-6 I +

                                               I 3-6 I + I 6-6 I + I 12- 6 I + I 9-6 I + I 4-6 I) /10

         = (28)/10

        =  2.8

Solution 4:

Mean= (30+46+25+45+18+25+15+32+40+24)/10

            =  300/10

            =  30

Mean absolute deviation  = ( I 30-30 I + I 46-30 I + I 25-30 I + I 45-30 I +

                                               I 18-30 I + I 25-30 I + I 15-30 I + I 32-30 I +

                                               I 40-30 I + I 24-30 I) /10

         = (86)/10

        =  8.6

875 yearbooks.

Step-by-step explanation:

To maximize profit, at $8125 prices should the school charge for the yearbooks

Simplify first the equation,

R(x) = 25000 - 2500x + 6250x - 625x²

Then, we differentiate the equation and equate to zero.

dR(x) = -2500 + 6250 - 1250x = 0

The value of x from the equation is 3.

(1) The price is equal to 50 - 5(3) = $35.

(2) The possible maximum revenue:

R(x) = 2500 - 2500(3) + 6250(3) - 625(3²) = $8125

Answer:

J

Step-by-step explanation:

The amount he is spending PER DAY is always a variable multiplied by its rate. That will be 8d.

Then you have a MAXIMUM amount of 3,000. That means the amount has to be less than or even equal to 3,000 but no more.

So 8d ≤ 3000 would be the answer

I believe the answer would be J. whenever the open part of the sign is towards a number or value, that means it is greater than the other number on the other side. For example 5 is less than 6 so 5 < 6. whenever the sign in between and has a line underneath it, it means it can also be equal to the number. therefore d is the amount per day and you pay that much for 8 days, so you get 8d. Now we know you can spend $3000, but no more. so you would use this sign < with a line drawn underneath it. now you would have 8d <(with a line underneath) 3000. this means that I'd must be equal to $3000 or less than $3000.
