Answer:

Step-by-step explanation:
Area of triangle = 0.5 × Base × Height
→ Substitute in the values
200 = 0.5 × 5x × 5x
→ Simplify
200 = 12.5x²
→ Divide both sides by 12.5
16 = x²
→ Square root both sides
4 = x ∴ x = 4
Answer:
$27.90
Step-by-step explanation:
Step 1: Find how much 4 large necklaces will cost
$5.70 * 4 = $22.80
Step 2: Add the cost of 4 large necklaces to the price of 1 small necklace
$22.80 + $5.10 = $27.90
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange - 3x + 4y = 5 into this form
Add 3x to both sides
4y = 3x + 5 ( divide all terms by 4 )
y =
x +
← in slope- intercept form
with slope m = 
• Parallel lines have equal slopes, thus
y =
x + c ← is the partial equation of the parallel line
To find c substitute (2. 1) into the partial equation
1 =
+ c ⇒ c = - 
y =
x -
← equation of parallel line
Sinθ=opposite side/hypotenuse
cosθ=adjacent side/hypotenuse
where both the sides are relative to theta.
in this case, 22 is your hypotenuse. theta (θ) is the angle you are examining. i've included a diagram for reference because the equations may format differently depending on which angle you choose as theta.
using my diagram:
sinθ = o/h
sin 15 = o/22
sin 15(22) = o
o=5.69m/s
therefore the vertical component is about 5.69m/s.
cosθ=a/h
cos15 = a/22
cos15(22) = a
a = 21.25m/s
therefore, your horizontal component is about 21.25m/s.
Answer:
C: y + 1 = 6/7(x + 3)
Step-by-step explanation:
(5 + 1)/(4 + 3) = m
6/7 = m
y - 5 = 6/7(x - 4)
y - 5 = 6/7x - 24/7
y = 6/7x + 11/7
