Answer:
area of rhombus = 1/2 
half * diagonal 1 * diagonal 2 is the area of rhombus.
hope this answer helps you...
please mark as brianliest.. thank you!
The area of the figure is 26 square units. There is 6 of a 2 which adds up 12 and there is one 8 and adding it with 12 would be 20. The last number was a 6 so you add 20 with 6 which adds up of 26 square units. So the area Of the firgure is 26 square units.
Answer:
22.5
Step-by-step explanation:
To find the rate of speed per hour, you need to divide the kilometer (90) by the hours (4).
90/4=
22.5
Answer:
x = 5/4
Step-by-step explanation:
By combining like terms, you get 8x = 10.
Divide the 8 on both sides of the equation.
x = 10/8
This, however, can be simplified by dividing by 2. This ultimately gives us 5/4.
By converting into parametric equations,
<span><span>x(θ)=r(θ)cosθ=cos2θ<span>cosθ
</span></span><span>y(θ)=r(θ)sinθ=cos2θsinθ</span></span>
By Product Rule,
<span>x'(θ)=−sin2θcosθ−cos2θsinθ</span>
<span>x'<span>(π/2)</span>=−<span>sin(π)</span><span>cos<span>(π/2)</span></span>−<span>cos(π)</span><span>sin<span>(π/2)</span></span>=1</span>
<span>y'(θ)=−sin2θsinθ+cos2θcosθ</span>
<span>y'<span>(π/2)</span>=−<span>sin(π)</span><span>sin<span>(π/2)</span></span>+<span>cos(π)</span><span>cos<span>(π/2)</span></span>=0</span>
So, the slope m of the curve can be found by
<span>m=<span>dy/dx</span><span>∣<span>θ=<span>π2
</span></span></span>= <span><span>y'<span>(π/2)/</span></span><span>x'<span>(π/2)
</span></span></span></span>=0/1
=0
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
