The 10th term of an a.p is -27 and the 5th term is -12 .find the first term?

horsena [70]

Step-by-step explanation:

$a_{10} = - 27... (Given) \\\\\therefore a + 9d = - 27...... (1)\\\\a_{5} = - 12... (Given) \\\\\therefore a + 4d = - 12.......(2)\\\\$

Subtracting equation (2) from equation (1)

$a + 9d-( a + 4d )= - 27-(-12)\\\\\therefore a +9d - a-4d = - 27+12\\\\\therefore 5d = - 15\\\\\therefore d = \frac {- 15}{5}\\\\\huge \orange {\boxed {\therefore d = -3}} \\\\$

Substituting d = - 3 in equation (1), we find:

$a + 9\times (-3)= - 27\\\\\therefore a - 27 = - 27\\\\\therefore a = 27- 27\\\\\huge \red {\boxed {\therefore a = 0}}\\\\$

Hence, first term is zero.

Find the area of the kite

Leya [2.2K]

Answer:

144ft^2

Step-by-step explanation:

since it's a kite, there are two pairs of congruent (exactly the same shape) triangles

bc of this you can find one triangle from each pair and double it

e.g.

$\frac{6 \times 8}{2}=24$

$\frac{12 \times 8}{2}= 48$

so you would do 2(24+48)=144

Since it arrived at a safari park, a giraffe's height has increased from 8 <img src="https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%

romanna [79]

It's A.

8 1/2 ÷12 3/4 × 100 = 66.66667%
100% - 66.66667% = 33.33333%

This wasn't an option, but the closest estimate to this is: 30%, so it's A.
