Which is the equation of a line that has a slope of -2/3 and passes through point -3 -1?
Answer: y= -2x/3 -3
Step-by-step explanation:
Substitute the x and y values from the given coordinate into the slope-intercept formula and solve for b
y = mx + b
-1 = -2/3(-3) + b
-1 = 2 + b
-1 -2 = b
-3 = b The y-intercept is -3
the equation: y = -2x/3 - 3
A fireman spots a stranded woman in the window of a 200-foot tall office building. From the
point where the fireman is standing, the angle of elevation to the stranded woman is 42° 33'
and to the top of the building is 58° 6'. How far from the ground is the stranded woman?
Answer:
114.3 foot
Step-by-step explanation:
Height of building,h=200 foot
Let BC=x
[tex]tan\theta=\frac{perpendicular\;side}{base}[/tex]
Using the formula
[tex]tan(58^{\circ} 6')=\frac{200}{CD}[/tex]
[tex]CD=\frac{200}{tan(58^{\circ} 6')}[/tex]
[tex]CD=124.5 foot[/tex]
Now,
[tex]\frac{BC}{CD}=tan(42^{\circ}33')[/tex]
[tex]\frac{x}{124.5}=0.9179[/tex]
[tex]x=124.5\times 0.9179[/tex]
[tex]x=114.3 foot[/tex]
Hence, the distance of woman from the ground=114.3 foot
The ground is 123.24 ft far from the stranded woman.
Given the total height of the office building is 200 ft.
And the angle of elevation of the top of the building is 58° 6' and the angle of elevation to the stranded woman is 42° 33'.
We know that, from trigonometric ratios,[tex]tan \theta =\frac{perpendicular}{base}[/tex]
here [tex]\theta[/tex] is the angle of elevation of the top of the building from the fireman.
Now, [tex]tan ( 58^{0} 6')[/tex][tex]=\frac{200}{base}[/tex]
[tex]1.488=\frac{200}{base}[/tex]
[tex]base=\frac{200}{1.488}[/tex]
[tex]base=134.40[/tex] ft
Now the woman is stranded in the window of the building say at the height of h ft, and the angle of elevation of the woman from the fireman is 42° 33'.
So, [tex]tan (42^{0} 33')[/tex][tex]= \frac{perpendicular}{base}[/tex]
[tex]tan(42^{0} 33' )= \frac{h}{134.40}[/tex]
[tex]0.917=\frac{h}{134.40}[/tex]
[tex]0.917\times134.40=h[/tex]
[tex]h=123.24 ft[/tex]
Hence the ground is 123.24 ft far from the stranded woman.

Which are true if figure DEFG is reflected across the x-axis? Check all that apply.
D(0, 4) → D'(0, –4)
E(–2, 0) → E'(–2, 0)
The perpendicular distance from G' to the x-axis will equal 2 units.
The perpendicular distance from D' to the x-axis will equal 8 units.
The orientation will be preserved.
Answer:
A,B,C
Step-by-step explanation:
If figure DEFG is reflected across the x-axis, the correct statements are:
D(0, 4) → D'(0, –4)
E(–2, 0) → E'(–2, 0)
The perpendicular distance from D' to the x-axis will equal 8 units.
Options A, B, and E are the correct answers.
What is a reflection?There are two ways of reflection.
Along x-axis:
(x, y) – (x, -y)
Along y-axis:
(x, y) - (-x, y)
We have,
D(0, 4) → D'(0, –4) - True.
Reflecting a point across the x-axis negates its y-coordinate.
E(–2, 0) → E'(–2, 0) - True.
Reflecting a point across the x-axis does not change its x-coordinate.
The perpendicular distance from G' to the x-axis will equal 2 units. - False. The perpendicular distance from G' to the x-axis will be the same as the perpendicular distance from G to the x-axis.
The perpendicular distance from D' to the x-axis will equal 8 units. - True.
The perpendicular distance from D' to the x-axis will be the same as the perpendicular distance from D to the x-axis, which is twice the distance between D and the x-axis.
The orientation will be preserved. - False.
Reflecting a figure across the x-axis will reverse the orientation of the figure.
Thus,
D(0, 4) → D'(0, –4) - True
E(–2, 0) → E'(–2, 0) - True
The perpendicular distance from D' to the x-axis will equal 8 units. - True.

Jonathan will run a 614-mile relay with 4 other team members, where each team member runs an equal distance. How many miles will Jonathan run?
Answer: Jonathan will rum [tex]1\dfrac14\text{ mile}[/tex] .
Step-by-step explanation:
Given: Total distance to run =[tex]6\dfrac14[/tex] miles [tex]=\dfrac{25}{4}[/tex] miles
Total members = 1+4 = 5
if each member runs equal distance.
Then, each member will run = [tex]\dfrac{\text{Total distance}}{\text{Total members}}[/tex]
[tex]=\dfrac{\dfrac{25}{4}}{5}\\\\ \lim_{n \to \infty} a_n =\dfrac{25}{4\times5}\\\\=\dfrac{5}{4}\\\\ = 1\dfrac14 \text{miles}[/tex]
Hence, Jonathan will rum [tex]1\dfrac14\text{ mile}[/tex] .

How do I Invert 6/7? Please help me because I am confused!
Answer:
The invert part of “invert and multiply” means to take the denominator of this big fraction, 1/4, and invert it. In other words, flip it on its head so its numerator becomes its denominator and vice versa. The inverse of 1/4 is therefore 4/1, or just 4.

What are proportions?Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.
To find the value of x:
So, 12:x::9:3
⇒ 12×3=x×9
⇒ 9x=36
⇒ x=36/9
⇒ x=4
