PLEASE HELP WITH THIS QUESTION​

Step-by-step explanation:

the equation of the circle centered at (-3, – 10)

=> (x+3)²+(y+10)²=2²

<=> x²+6x+9+y²+20y+100=4

x²+y²+6x+20y+105=0

Let's see

[tex]\\ \rm\dashrightarrow (x-h)^2+(y-k)^2=r^2[/tex]

[tex]\\ \rm\dashrightarrow (x+3)^2+(y+10)^2=2^2[/tex]

[tex]\\ \rm\dashrightarrow (x+3)^2+(y+10)^2=4[/tex]

[tex]\\ \rm\dashrightarrow x^2+y^2+6x+20y+105=0[/tex]

Answer:

Step-by-step explanation:

take 43 degree as reference angle

using tan rule

tan 43 = opposite / adjacent

0.93 = x / 56

x = 56/0.93

x = 60.21

x = 60.2

Answer:

(3-x) is the other factor.

Step-by-step explanation:

The given function is :

[tex]F(x)=-x^{2}+7x-12[/tex]

One of the factor is (x-4)

We need to find the other factor.

It can be solved as follows :

[tex]F(x)=-x^{2}+4x+3x-12\\\\=(-x+3)(x-4)[/tex]

So, the other factor is (3-x).

Answer:

  -x +2

Step-by-step explanation:

The expression can be simplified as follows.

  [tex]\sqrt{x^2-4x+4}=\sqrt{(x-2)^2}=|x-2|[/tex]

For negative values of its argument, the absolute value changes the sign.

For x < 1, x-2 is negative, so the simplified form is ...

  -(x -2) . . . . . for x < 1

  -x +2 . . . . . for x < 1

Step-by-step explanation:

magic

The region with the competition for resources is region C with the highest population density

The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Numerous creatures' distribution, growth, and migration can all be explained by population density.

Population density = number of people / the area they occupy

Given data ,

Let the population density be represented as P

Region    Population    Area

A               1,312       212

B               630         314

C               16,400     625

D               17,800      902

Now , the state with the highest population density will have the greater competition for the resources

So , The population density in Region A = 1312 / 212 = 6.19

The population density in Region B = 630 / 314 = 2

The population density in Region C = 16400 / 625 = 26.24

The population density in Region D = 17800 / 902 = 19.7

Hence , the region C has the highest population density

Answer:

y = 3x+7

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 3x+7

Answer:

imagine a triangle

one side is just upwards trough the cone, one side is the radius of the circle and the last one is the slant height.

remember the pythagoras stuff

so

(slantheight)² = radius² + height²

or finally:

slantheight = squareroot (radius² + height²)

Answer:

The angles measured between the shadow and the wall trim and the shadow and the top or bottom of the picture should be equal if the picture is level

Step-by-step explanation:

Whereby the picture is 12 inches above the wall trim and the Sun is casting a shadow on the wall, therefore, the edges of the shadow of a straight edged object is straight

If the picture is level, the shadow cast by the sun is transversal to the wall trim and the line formed by extending the bottom or top of the picture in the direction of the shadow. That is, if the picture is parallel, the shadow cast by the Sun on the wall is transversal to the picture and the wall trim if or when the shadow eventually crosses the picture

With the protractor, the angle between the shadow and the wall trim and the shadow and the top or bottom is measured

The angles measured should be the same if the picture is level.

Answer:

[tex]y=-\frac{1}{4} x+6[/tex]

Step-by-step explanation:

To find the perpendicular line of y=4x-5 you need to substitute to its slope (4), the anti-reciprocal number (-1/4).

Now you know the slope of the second line let's find the y-intercept (which is the point 0,6):

[tex]y=-\frac{1}{4} x+6[/tex]

Answer:

22 exhibits

Step-by-step explanation:

We are told from the above question that:

Sandy went to her local zoo where 50% of it's exhibits featured reptiles.

If the zoo features 44 exhibits in total, then the number of the zoo's exhibits that feature reptiles is calculated as:

50% of 44

50/100 × 44

= 50 × 44/100

= 22

Therefore, the number of the zoo's exhibits that feature reptiles is 22 exhibits.

Answer:

V = 211.56 mm

Step-by-step explanation:

The volume of a pyramid :

V = 1/3(Lenght * width * height)

Length = 9mm

Width = 8.2 mm

Height = 8.6 mm

Hence, we have ;

V = 1/3(9 * 8.2 * 8.6)

V = 1/3 * 634.68

V = 211.56 mm

Answer:

Step-by-step explanation:

Answer:

i. Two angles can be vertical and supplementary.

ii. Yes, we can determine the angles.

Step-by-step explanation:

When two angles are vertical, it implies that they are equal (with respect to vertical opposite property). While two angles are supplementary if and only if they add up to 180 degrees .

It is not mandatory for the two angles to be beside each other so as to be supplementary. So that in this special case, the only measure of angles that can be both vertical and supplementary is 90 degrees .

Answer:

64 × pi m²

Step-by-step explanation:

the formulas needed for the surface area of a cone are :

base area plus the "mantle", the lateral "wall" around it.

the base area is a circle.

so, that formula is Ac = pi×r²

the "wall" formula is Aw = pi×r×s

r = radius

s = slant height = 12

the formula for the surface area of a sphere is

As = 4×pi×r²

we know now, that both surface areas are the same, and also the radius is the same for both objects.

Ac + Aw = As

pi×r² + 12×pi×r = 4×pi×r²

=>

12×pi×r = 3×pi×r²

12×pi = 3×pi×r

12 = 3×r

r = 4 m

now, we only need to use this value of r in our formulas for surface areas, like for the sphere :

4×pi×r² = 4×pi×4² = 4³×pi = 64×pi
