18<-3(4x-2)
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
What is the median of the data set? 15, 19, 20, 22, 26, 30, 31
O A. 15
O B. 31
O c. 22
O D. 7.
Answer:
C. 22
Step-by-step explanation:
The median is the middle number of the set if the numbers are in order from least to greatest.
This set of numbers is in order, so the median is the middle number = 22

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.
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
A line that includes the point (-10,-5) has a slope of -8. What is its equation in point-slope form?
Answer:
Step-by-step explanation:
y + 5 = -8(x + 10)
y + 5 = -8x - 80
y = -8x - 85
Answer:
[tex]y + 5 = -8 (x+10)[/tex]
Step-by-step explanation:
The point-slope form of an equation is represented by the formula [tex]y-y_1 = m (x-x_1)[/tex]. Substitute values for the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula to write the equation of the line in point-slope form.
[tex]m[/tex] represents the slope, so substitute -8 in its place. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects. Thus, use the x and y values of the point (-10, -5) for the formula. Substitute -10 for [tex]x_1[/tex] and -5 for [tex]y_1[/tex]. This gives the following equation and answer:
[tex]y-(-5) = -8(x-(-10)\\y + 5 = -8 (x+10)[/tex]

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.

A publishing house is selling subscriptions to its magazines for 20% off the original price. If a subscription to Newsweek Magazine is on sale for $72, how much does it usually cost?
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

6a+4b−66, a, plus, 4, b, minus, 6 when a=1a=1a, equals, 1 and b=3b=3b, equals, 3.
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.

[tex]x^{2} +9y^{2} =1[/tex] is an ellipse. The line y=mx+2 is tangent to the ellipse. Determine the value of ([tex]m^{2}[/tex]). Express your answer as an integer or as a common or improper fraction.
9514 1404 393
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

B. y = 3x + 5
C. y = 5x + 3
D. y = -5x - 3
please help
Answer:
B
Step-by-step explanation:
We want to find the equation of a line with a slope of 3 that includes the point (0, 5).
We can use the slope-intercept form, given by:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
Notice that the given point (0, 5) is already the y-intercept. So, b = 5.
By substitution, we acquire:
[tex]y=3x+5[/tex]
Hence, our answer is B.
Answer:
B: y=3x+5
Step-by-step explanation:
the line crosses the y axis at point 5, the slope is 3

use the geometric mean theorems to find AC and BD. BA=20 BC=15
Step-by-step explanation:
first, you use the pythagorean theorem to find the missing side of the original and big triangle.
[tex]20 {}^{2} + 15 {}^{2} [/tex]
next, you simplify these into actual numbers
[tex]400 + 225[/tex]
after, you add these numbers together and find the square root.
[tex]\sqrt{625} = 25[/tex]
you have the answer for AC. next you need to find BD. of you line up BC with BD, BC would be longer, , so you know its shorter, but not by much, so I'd assume to guess like 13 for BD- that's just me- but I'm not sure how to exactly find it.
The requried Measure of the BD and AC in the given question is 17.32 and 25 respectively.
What is the geometric mean theorem?The geometric mean theorem for a right triangle states that the length of the altitude (height) to the hypotenuse of a right triangle is the geometric mean of the lengths of the two segments of the hypotenuse.
Here,
From the triangle, following the Geometric mean theorem,
BD = √[AB×BC]
BD = √[20×15]
BD = √17.32
Now,
Applying the Pythagorean theorem to find AC,
AC = √15² + 20²
AC = 25
Thus, the requried Measure of the BD AC in the given question is 17.32 and 25 respectively.
