Answer:
(½x+½y)²=6
Step-by-step explanation:
x^2 + y^2 = 14, xy=5
(A+B)^2=A^2 +2AB+B^2... (*)
(1/2x+1/2y)^2 =(*)
(1/2x)^2 +2(1/2x)(1/2y)+(1/2y)^2 =
1/4x^2 +1/2xy+1/4y^2=
1/4(x^2 +y^2) +1/2(xy)=
1/4*14+1/2*5=
14/4+5/2=
14/4+10/4=
24/4=6
let me know if I'm wrong.
Answer:
adi's height = n-t inches
Step-by-step explanation:
from this question
we have Adi to be t inches shorter than sunnee.
sunnee's height = n inches tall
to get adis height, we have to subtract the height difference t from sunnee's height.
the height difference is how many inches by which Adi is shorter = t
adies height = sunnee's height, n - difference in height, t
= <em><u>(</u></em><em><u>n-t)</u></em><em><u> </u></em><em><u>inches</u></em>
<em><u>this </u></em><em><u>expression</u></em><em><u> </u></em><em><u>represents</u></em><em><u> </u></em><em><u>adis</u></em><em><u> height</u></em><em><u> </u></em><em><u>in </u></em><em><u>inches </u></em><em><u>.</u></em>
Answer:
cos B= 7/25
tan B = 24/7
sin B = 24/25
Step-by-step explanation:
cos B= adjacent/hypotenuse = 7/25
tan B = opposite/adjacent = 24/7
sin B = opposite/hypotenuse = 24/25
Cross multiply and set it up like this.
1800 X
------- • -------
80 24
Multiply 1800•24
Then divide by 80 and you get 540.
