Answer:
$50.40
Step-by-step explanation:
The garden has an area of ...
(15 ft)(12 ft) = 180 ft²
Amy wants to cover 1/4 of that with flowers, so the area devoted to flowers is ...
(1/4)(180 ft²) = 45 ft²
The cost for each square foot is $1.12, so the cost of the flowers will be ...
($1.12/ft²) × 45 ft² = $50.40 . . . . cost to cover 1/4 of the garden with flowers
To solve this problem yo need to have the "x", the "y", and the radius. To find the radius since it is not given we use the formula.
sq rt(-3^2+1^2)
sq rt(9+1)
sq rt(10) would be the length of the radius in this case.
Then we use the sine cosine and tangent fractions
sin:y/r
cos:x/r
tan:y/x
With the values plugged in the equations are
SIN:1/sqrt(10) Since there can´t be a sq rt in hte denominator we change it to 1(sq rt(10))/10
COS:-3/sqrt(10) Since there can´t be a sq rt in the denominator we change it to -3(sq rt(10))/10
TAN:1/-3 This one can stay the same.
This would be the measures of SIN, COS, and TAN.
Answer: 0.5
Step-by-step explanation:
L×L= area
L^2=0.25
Square root both sides
L=√0.25
L=0.5
Answer:
y=3
Step-by-step explanation:
Multiply 9 from both sides to cancel it out.
-27=-y/9
/9 /9
-3=-y
We can't have a negative variable, so we divide -1 from both sides.
-3=-y
/-1 /-1\
3=y
