Answer:

Assuming the shape is a half-circle, there's two right angles.

Step-by-step explanation:

The angle between the straight segment and the half-circle can be measured by taking a tangent line at the intersection point and it will of course be perpendicular to the straight segment, assuming the segment is the diameter of the circle).

Answer:

  m^2 = 35/9

Step-by-step explanation:

The line will be tangent to the ellipse where there is one point of intersection between the line and the ellipse. We can find that case by looking at the discriminant of the quadratic.

  x^2 +9(mx +2)^2 = 1

  x^2 +9(m^2x^2 +4mx +4) = 1

  (9m^2 +1)x^2+36mx +35 = 0 . . . . subtract 1, collect terms

__

Then the discriminant is ...

  (36m)^2 -4(9m^2 +1)(35)

We want it to be zero, so we have ...

  1296m^2 -1260m^2 -140 = 0 . . . . eliminate parentheses

  36m^2 = 140 . . . . . . . . . . . . . . . add 140

  m^2 = 140/36 . . . . . . . . . . . . divide by 36

  m^2 = 35/9

Answer

x [tex]\leq[/tex] -1

Step-by-step explanation:

Answer:

x < - 1

Step-by-step explanation:

Given

18 < - 3(4x - 2)

Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.

- 6 > 4x - 2 ( add 2 to both sides )

- 4 > 4x ( divide both sides by 4 )

- 1 > x , then

x < - 1

Step-by-step explanation:

Reflecting over the y-axis changes the only the first point changes into a negative, while the second stays the same.

The point (4,9) corresponds to the number of birds in the population when the biologists discovered it.

The function is a type of relation, or rule, that maps one input to a specific single output.

Biologists discovered an invasive bird species on an island.

The function fff models the population size (in hundreds of birds) for this species as a function of time (in months) after being discovered.

The population drops after 4 months making that the maximum the population of the fish.

The answer will be (4,9) the vertex of the parabola which is basically the top of the peak.

The point (4,9) corresponds to the number of birds in the population when the biologists discovered it.

180-157

Answer:

90

Step-by-step explanation:

The magazines are sold at a discount. Discount reduces the price of the good

If the magazines are sold at 20%, the magazine's price would be 80% (100% - 20%) of the original price

let a represent price of the magazine before the discount

This equation represents price of the magazine after the discount

0.8 x a = $72

Divide both sides by 0.8 and find a

a = $90

Answer:

less than 2

Step-by-step explanation:

Hello There!

If x varies with y and has a constant rate of change of 6 then we can create an equation to solve for y

y = 6x

Now we want to find x when y = 11

given the y value we plug in 11 to y

11 = 6x

now we solve for x

step 1 divide each side by 6

6x/6

11/6=1.83

we're left with x = 1.83

so we can conclude, when y = 11 x is less than two

extra notes:

because y values directly with x we are using a y = kx equation therefore we don't have to worry about a y intercept because the y intercept would be 0

domain(0,0) the range is (-3,0)

Step-by-step explanation:

give me the brinalst plzz i slove ur answer

The domain and range of function is (0,8).

The domain of a function is defined as the set of all the possible input values that are valid for the given function.

The range of a function is defined as the set of all the possible output values that are valid for the given function.

Given;

The graph

Now

The domain is on x axis (0,8)

The range is on y axis (-3,9)

When x<4, both are positive.

Therefore, the domain answer will be (0,8).

Answer:

10.75 inches

Step-by-step explanation:

A 44-inch pendulum swings at an angle of 14°. Find the length of the arc to the nearest hundredth of an inch through which the tip of the pendulum swings.

The formula of the length of the arc subtended by pendulum is given as = (x/360)*2πr or (x/180)*πr

Where:-

x = angle subtended by pendulum which is = 14°

r = Length of the pendulum = 44 inch

Lenghth of arc = ?

By putting values

Length of the arc = (14/180 × π × 44

= 10.751228192 inches

Approximately = 10.75 Inches

Answer:

The answer is 12.

Step-by-step explanation:

We need to find the value of the given expression 6a+4b−6 when a = 1 and b = 3

Put a = 1 and b = 3 in the above expression.

6a+4b−6 = 6(1) +4(3) -6

= 6+12-6

= 12

So, the value of the given expression is equal to 12.
