The answer 5 times 20 equals 100
Here is the complete question.
Answer:
3.7 meters
Step-by-step explanation:
From the given information:
The radius is 3m
The central angle XYZ = 70°
To calculate the circumference of the circle:
C = 2 π r
C = 2 × 3.142 × 3
C = 18.852 m
Let's recall that:
The circumference length define a central angle of 360°
The approximate length of minor arc XZ can be determined as follow:
Suppose the ≅ length of minor arc XZ = Y
By applying proportion;
Y(360) = 18.852 × 70
Y = 1319.64/360
Y = 3.66
Y ≅ 3.7 m

-5x+y=-3. (1) isolate y 1.First isolate a variable.( I isolated y because it was already isolated)
3x-8y=24. (2). 2.Then substitute that into the other equation
—————. 3. Then solve for X
Sub y=5x-3 into (2). 4. Then substitute X into one of the equations
5. Then solve for Y and ta-da you find the answer.
3x-8(5x-3)=24.
3x-40x+24=24. Hope this helped! :)
3x-40x=24-24
-37x=0
X=0
——————
Sub x=0 into (1)
-5(0)+y=-3
Y=-3
.: (0,-3)
For x=1
h(2)=h(1)+h(0)
h(2)=12+3
h(2)=15
for x=2
h(3)=h(2)+h(1)
h(3)=15+12
h(3)=27
for x=0
h(1)=h(0)+h(-1)
12=3+h(-1)
h(-1)=12-3
h(-1)=9
