Answer:
Step-by-step explanation:
The general equation is y = mx + b
You already have m which is the slope. So the general equation becomes y = -5x + b
The point is meant to find b
x = - 4
y = 7
7 = - 5*-4 + b
7 = 20 + b Subtract 20 from both sides.
7 - 20 = 20-20 + b Combine
- 13 = b
Answer: y = - 5x - 13

An incident ray of light strikes water at an angle of 30°. The index of refraction of air is 1. 0003, and the index of refraction of water is 1. 33. What is the angle of refraction rounded to the nearest whole number? 22° 24° 30° 42°.
The measure of the angle of refraction is 22 degress, the correct option is A.
What is the angle of refraction?
The angle made by a refracted ray with a perpendicular to the refracting surface.
Given
An incident ray of light strikes water at an angle of 30°.
The index of refraction of air is 1. 0003, and the index of refraction of water is 1. 33.
In order to determine the angle of the refracted ray, we may apply Snell's law, which states that the ratio of the sines of the angles of incidence and refraction is constant for a given wave when it passes through two different media.
The angle of the refraction is given by;
[tex]\rm 1.0003 \times sin(30) = 1.33 \times sin(\phi)\\\\ \rm 1.0003 \times 0.5 = 1.33 \times sin(\phi)\\\\Sin\phi=\rm \dfrac{1.0003 \times 0.5 }{1.33}\\\\Sin\phi=0.37\\\\\phi = 22[/tex]
Hence, the measure of the angle of refraction is 22 degress.

The measure of angledcg is 145°. point c has four lines extending from it. one line extends to point d, another extends to point e, another extends to point f, and another extends to point g. angle e c f is 20 degrees. angle f c g is 25 degrees. what is mangledce? 90° 100° 180° 190°
The measure of ∠DCE is 170°.
∠ECF = 20°
∠FCG=25°
∠GCD=145°
Suppose ∠DCE = x
What is the sum of all angles at a point?The Sum of all angles at a point is 360°.
∠ECF +∠FCG+∠GCD+∠DCE =360°
20+25+145+x =360
x =170°
∠DCE = 170°
Therefore, the measure of ∠DCE is 170°.

A farmer has 540 m of fencing to enclose a
rectangular area and divide it into two sections as
shown.
a) Write an equation to express the total area
enclosed as a function of the width.
b) Determine the domain and range of this area
function.
c) Determine the dimensions that give the
maximum area.
The dimensions that give the maximum area is 135 m by 135 m for a rectangular area with 540 m of fencing
What is an area?An area is the amount of space occupied by a two dimensional shape or object.
Let w represent the width and l represent the length, hence:
540 = 2(l + w)
l = w - 270
The area (A) is:
A = length * width
A = w(w - 270) = w² - 270w
The domain of the function is (270, ∞), the range is (0, ∞).
The maximum area is at dA/dw = 0, hence:
2w - 270 = 0
w = 135 m, l = 270 - w = 135 m
The dimensions that give the maximum area is 135 m by 135 m

Janelle plants 14 carrot plants for every 6 tomato plants in her garden. What is the ratio of carrot plants to total plants in Janelle’s garden?
Answer:
14:20 or 7:10
Step-by-step explanation:
The ratio of the carrots to tomatoes is 14:6 therefore if she plants 20 vegetables, she'll have 14 carrots and 6 tomatoes. Therefore the ratio of carrots to the total plants is 14:20 which is equal to 7:10

HELP ASAP!!!!!! 65 POINTS!!!
Answer:
CD =7.5 AC =20
Step-by-step explanation: you can answer this question by creating a proportion. For the side AB, we can find the total length by adding AE and EB, for a total of 8. Now we can build a proportion, where x equals AC. 12.5/x= 5/8. When you build a proportion, it’s important to make sure you use the same corresponding parts in the same places, for example, in both the fractions we made for the proportion, the total side length was on the bottom. From this proportion, we now cross multiply to get 5x=100. Divide both sides by 5 and you get that the length of AC is 20. We can do the same with CD. The proportion you’d use to find CD would involve the smaller line segment over the total length of the line. This would look like so: x/20=3/8. Cross multiply again and you’d get 60=8x. Divide both sides by 8 and you’d get x=7.5. This means the length of CD is 7.5.
