Answer:

The correct option is the letter "C", [tex](x + 2)^2 + (y + 10)^2 = 1.44[/tex].

Step-by-step explanation:

The standard form for a circle's equation has the following structure:

[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]

Where [tex](x_c,y_c)[/tex] are the coordinates of the center of the circle and [tex]r[/tex] is the radius. Applying the data from the problem we have:

[tex](x - x_c)^2 + (y - y_c)^2 = r^2\\\[[x - (-2)]^2+ [y - (-10)]^2 = (1.2)^2\\(x + 2)^2 + (y + 10)^2 = 1.44[/tex]

Therefore the correct answer is the letter "C", [tex](x + 2)^2 + (y + 10)^2 = 1.44[/tex].

Answer:

A. 240/7

Step-by-step explanation:

10^4x/24 * 10^3x/24 = 10^10

10^7x/24 = 10^10

7x/24 = 10

x = 240/7

Answer:

x = -2

Step-by-step explanation:

7(2 - x) = 28

Distribute

14 -7x = 28

Subtract 14 from each side

14-7x-14 = 28-14

-7x = 14

Divide each side by -7

-7x/-7 = 14/-7

x = -2

Answer:

1. 17/12

2. 12/17

Step-by-step explanation:

The teacher is 1.42 times as tall as the student and the required fraction is given by 17/12

The quantitative relation between two amounts shows the number of times one value contains or is contained within the other. for example-"the ratio of computers to students is now 2 to 1"

Given here; Height of the student = 4 ft. and height of teacher =5²/₃

Ratio of the height of the teacher and student is

= 5+2/3  / 4   ( 5²/₃=5+2/3 , property of mixed fractions)

= 17/3 × 1/4

=17/12

=1.4166

Thus we can say that the height of teacher is 1.42 times as tall as the student.

Also as given above the teacher's height is 17/12 the students height.

Hence, The teacher is 1.42 times as tall as the student and the required fraction is given by 17/12

Step-by-step explanation:

Deposit means add

2300+ 345+30+600 =3275

Withdrawal means subtract

3275-350 =2925

Answer:

Either x+15 or x-17.

Step-by-step explanation:

Answer:

7920, 2925

Step-by-step explanation:

The four-digit number has to be a multiple of 5 and also a multiple of 9. So, the last number is either a 0 or a 5, and the addition of the 4 digits must be equal to 9, 18, 27, et cetera, like every multiple of 9.

For the case: _920, the addition of digits gives 11, then the only possible first digit is 18-11 = 7

For the case: _925, the addition of digits gives 16, then the only possible first digit is 18-16 = 2

Answer:

8.75 in.

Step-by-step explanation:

See attachment for the figure.

As you can see, ∆ HBA & ∆HKJ are similar,

HB/HA = HK/HJ  

3/5.25 = 8/HJ

3HJ/5.25 = 8

3HJ = 42

HJ = 14 in.

AJ = 14 - 5.25

AJ = 8.75 in.

Therefore,  the length of Line segment AJ is 8.75 in.

Answer:

[tex] \displaystyle 3 {x}^{2} + 4x - 1 = 0[/tex]

Step-by-step explanation:

we are given some coordinates

(1,6),(2,19),(3,38),(4,63),(5,94)

we want to figure out the quadratic equation which passes those coordinates

notice that, the coordinates in quadratic sequence

we know that,

A sequence is quadratic if and only if it has second difference

recall that,

these formulas are necessary to figure out a,b and c

because we know that

Quadratic equation standard form:

[tex] \displaystyle a {x}^{2} + bx + c = 0[/tex]

therefore to figure out a,b and c these formulas are important

let's figure out a:

we got that 2nd difference is 6 thus

[tex] \displaystyle 2a = 6[/tex]

divide both sides by 2

[tex] \displaystyle \frac{2a}{2} =\frac{ 6}{2}[/tex]

[tex] \displaystyle a = 3[/tex]

let's figure out b:

by using the second formula we can figure out b

our [tex]U_1[/tex] and [tex]U_2[/tex] are 6 and 19 respectively

substitute:

[tex] 3 \cdot 3 + b = 19 - 6[/tex]

simplify multiplication:

[tex]9+ b = 19 - 6[/tex]

simplify substraction:

[tex]9+ b = 13[/tex]

cancel 9 from both sides:

[tex]b = 4[/tex]

let's figure out c:

our [tex]U_1[/tex] is 6

substitute:

[tex] \displaystyle 3 + 4 + c = 6[/tex]

simplify addition:

[tex] \displaystyle 7 + c = 6[/tex]

cancel 7 from both sides:

[tex] \displaystyle c = - 1[/tex]

altogether substitute a,b and c to quadratic equation:

[tex] \displaystyle 3 {x}^{2} + 4x - 1 = 0[/tex]

and we are done!

Answer:

y=-4x+11

Step-by-step explanation:

We can use the point-slope form of a line to solve this, which is

y - y₁ = m (x - x₁), where (x₁ , y₁) is a point and m is the slope.

We have:

y - 3 = -4(x - 2)

y - 3 = -4x + 8

y = -4x + 11

Answer: 58.016

Step-by-step explanation:

Answer:

58.016

Step-by-step explanation:

9.8×5.92=58.016

Answer:

x = - 5, x = - 11

Step-by-step explanation:

Given

y = [tex]\frac{x+4}{(x+5)(x+11)}[/tex]

The denominator cannot be zero as this would make y undefined.

Equating the denominator to zero and solving gives the values that x cannot be, that is

(x + 5)(x + 11) = 0

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x + 11 = 0 ⇒ x = - 11

Thus

x = - 11 and x = - 5 are excluded values.

Answer:

95.36 ft

Step-by-step explanation:

Volume of a Cone[tex]=\frac{1}{3}\pi r^2 h[/tex]

Radius=7 ft, Height=12 ft

Therefore the volume of sand in the cone

[tex]=\frac{1}{3}\pi *7^2*12\\=615.7522$ ft^2[/tex]

If the sand was used to build as pyramid with a base of 4ft by 5ft.

Volume of a Pyramid[tex]=\frac{1}{3}*$Base Area* Height[/tex]

[tex]615.7522=\frac{1}{3}*(4*5)* Height\\615.7522=\dfrac{20}{3}* Height\\$Multiply both sides by \dfrac{3}{20}\\$Height =615.7522*\dfrac{3}{20}\\\\$Height of the pyramid=95.36 ft[/tex]
