8 0

Answer:

Step-by-step explanation:

in Δ ADM and Δ CBM

AD║BC and AC cuts it.

so ∠DAM=∠BCM  (alternate angle)

∠AMD=∠CMB ( vertically opposite angles)

AM=CM (given ,M is mid point of AC)

Hence ΔAMD ≡ ΔCMB (ASA=ASA)

AD=CB

The spring has a stiffness k=200n/m and is unstretched when the 25 kg block is at
g100num [7]
To solve this we are going to use the formula fro the force applied to a spring: F=ks
where
k is the spring constant 
s is the extension 

Since we know the F=ma, we can replace that in our formula and solve for a :
ma=ks
a= \frac{ks}{m}
where
a is the acceleration 
k is the spring constant
s is the extension 
m is the mass

We know for our problem that k=200, s=0.4, and m=25. So lets replace those values in our formula to find a:
a= \frac{ks}{m}
a= \frac{(200)(0.4)}{25}
a=3.5 \frac{m}{s^2}

We can conclude that the acceleration of the block when s=0.4m is 3.5 \frac{m}{s^2}.

Given the following pyramid identify the L, P, and B then find the surface area
Liula [17]

Answer:

slant length (l) = 7.5 m

perimeter of base P = 40 m

area of base B = 100 m^2

Surface Area = 250 m^2

Step-by-step explanation:

Surface area of a pyramid formula

1/2Pl + B

1/2 (40)(7.5) + 100

150 + 100 = 250 square meters
