a = (144/360) * π(10)²

a = 40π

Answer: 12 days

Step-by-step explanation:

Given

A community pool charges $78 for a swim lesson and $2 for a towel each day

Suppose Yolanda attended the session for x days

So, we can write the total fees of $102 as

[tex]\Rightarrow 102=78+2x\\\Rightarrow 2x=102-78\\\\\Rightarrow x=\dfrac{24}{2}\\\\\Rightarrow x=12[/tex]

So, Yolanda attended the swim lessons for 12 days

Answer:

3.125 miles

Step-by-step explanation:

5 × 0.625 = 3.125 miles

Answer:

79 minutes

Step-by-step explanation:

A plane is travelling at 180 meters per seconds

Convert to km/hr

180× 18/5

= 648 km/hr

Since 648 km equals 1 hour then the number of minutes required for the plane to travel 800 km is

= 1/648 × 800

= 1 hour 19 minutes

Conver the time to full minutes

60 minutes = 1 hour

= 60+19

= 79 minutes

Hence the minutes required for the plane to travel 800km is 79 minutes

Answer:

x = 10.2 m

Step-by-step explanation:

law of sines:

sin 30° / x = sin 69° / 19

cross-multiply:

.5(19) = sin 69°x

x = .5(19) / sin 69°

x = 9.5/.934

x = 10.2

The value of x with the help of sine law is 10.2 units.

Law of sines defines the ratio of sides of a triangle and their respective sine angles are equivalent to each other. The other names of the law of sines are sine law, sine rule and sine formula.

Here, Law of sines:

[tex]\frac{Sin A}{a} =\frac{Sin B}{b} = \frac{Sin C}{c}[/tex]

sin 30° / x = sin 69° / 19

1/2x =  sin 69° / 19

cross-multiply:

19/2 = sin 69°x

x = 9.5 / sin 69°

x = 9.5/0.934

x = 10.2

Thus, the value of x with the help of sine law is 10.2 units.

Answer:

TQ=SR [since it is isosceles trapezoid]

6x+1.2=9x-48

48+1.2=9x-6x

3x=49.2

x=49.2/3=16.4

now

QR=3×16.4+2.5=51.7

SR=9×16.4-48=99.6

ST=4×16.4-2=63.6

TQ=6×16.4+1.2=99.6

As it's isosceles trapezoid

Now

Answer:

A) all real numbers greater than or equal to 2

Domain: [tex]x\geq 0[/tex]

Step-by-step explanation:

The variable in the radical x cannot be less than 0 as that wouldn’t be defined. So, the maximum that x can be is 0, and [tex]y=x+2[/tex]. So, 0+2=2, and y is greater than or equal to 2.

Domain is x is greater than or equal to 0 because you cannot square a negative. So, it must not be less than 0. It could be 0 because square root of 0 is just 0.

Answer:

[tex]t=3.142sec[/tex]

Step-by-step explanation:

From the question we are told that:

Speed of ball [tex]V=35m/s\approx 80 mph[/tex]

Length of field [tex]l=110m[/tex]

Generally the equation for Time taken [tex]t[/tex] is mathematically given by

 [tex]t=m/V[/tex]

 [tex]t=110/35[/tex]

 [tex]t=3.142sec[/tex]

 [tex]t \approx \frac{3.142}{60}[/tex]

 [tex]t \approx 0.05hrs[/tex]

Therefore it will take the ball to get from one end of the field to the other

[tex]t=3.142sec[/tex]

Answer:

The image of the given points after the translation is;

(-1,13) , (-2,9) and (-1,-2)

Step-by-step explanation:

By translating vertically to the tune of 5 units, what we have done is to add 5 units to the y-axis value

so for (-1,8); it will become (-1, 8 + 5) = (-1,13)

for (-2,4); it will become (-2,4 + 5) = (-2,9)

for (-1,-7); it will become (-1,-7+ 5) = (-1,-2)

The vertex form of the equation is [tex]f(x) = (x+1/2)^2 + 3/4[/tex]

Given the expression [tex]f(x) = x^2 + x +1[/tex]

The vertex form is expressed as shown below:

[tex]f(x) = x^2 + x +1\\f(x) = x^2 + x + 1^2 +1 - 1^2\\f(x) = (x+1)^2 - 0[/tex]

Express the result in vertex form.

[tex]f(x) = (x+1/2)^2 + 3/4[/tex]

Hence the vertex form of the equation is [tex]f(x) = (x+1/2)^2 + 3/4[/tex]
