The volume of the base is 1.4 how I got the answer is by 3 times 7 that will give you 21 and you do 21 divided by 15 and your answer will be 1.4
Answer:
B. (-1, 2) and (4,7)
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
1) y = tan(xlnx-x+tan⁻¹(3) + 1)
2)
Step-by-step explanation:
1) y' = ln(x)(1 + y²), y(1) = 3 Ans y= tan(x lnx-x+1+tan⁻¹(3))
solution:
y' = ln(x)(1 + y²)
using condition y(1) = 3
tan⁻¹(3)=-1+c
c = tan⁻¹(3) + 1
now,
tan⁻¹(y)=xlnx-x+tan⁻¹(3) + 1
y = tan(xlnx-x+tan⁻¹(3) + 1)
2) y' = 9x² √(1 + x)³ (1 + y²), y(0) = 3
let 1+x³=u
inserting value of 'u' in equation above
inserting value y(0) = 3
c = tan⁻¹(3) - 2
Answer:
Area = 18
Step-by-step explanation:
Since the triangles are similar, we can set up a proportion of 10/4.5 = 40/x. The sides on top, with length 10 and 4.5, are similar. This ratio can then be applied to the areas, with the area of rectangle T in the numerator and the area of rectangle U in the denominator, giving us 40/x. To solve for x, we can multiply 40 by 4.5 and then divide the product by 10. This gives us 18, the area of rectangle U.
Answer:
Step-by-step explanation:
Given:
In Δ ABC
m∠C= 90°
For the triangle ABC we can apply trigonometric ratio to find m∠A.
We have:
Substituting values of side BC and AC
Taking inverse tan to get m∠A.
∴
AB can be found out using Pythagorean theorem:
AB being the hypotenuse can be written as
Substituting values of side BC and AC
Taking square roots both sides:
∴
