=1 I calculated the combine value
Answer:
The statement is true
Step-by-step explanation:
we know that
In a Rhombus the diagonals bisect opposite angles.
therefore
diagonal AD bisect angle D and angle A
so
m∠CDA≅m∠BDA
m∠CAD≅m∠BAD
diagonal CB bisect angle C and angle B
so
m∠ACB≅m∠DCB
m∠ABC≅m∠DBC
X^3 - 21x = -20
add 20 to both sides
x^3 - 21 x + 20 = 0
Rational Root Theorem:
Factors of P (constant) 20 = 1, 2, 4, 5, 10, 20
-------------------------------
Factors of Q (leading Coefficient) = 1
Possible zeros (all + -) 1/1, 2/1, 4/1, 5/1, 10/1, 20/1
Of the choices given only the number 1 is a possible root.
Answer:
Rent in 10th year = $5345.90
Step-by-step explanation:
Rent of apartment during first year = $1800 per month
But growth in rent with 11.5% per year will be represented by the exponential function,
Rent in 't'th year =
= ![1800(1+\frac{11.5}{100})^t](https://tex.z-dn.net/?f=1800%281%2B%5Cfrac%7B11.5%7D%7B100%7D%29%5Et)
= ![1800(1.115)^t](https://tex.z-dn.net/?f=1800%281.115%29%5Et)
Therefore, rent during 10th year will be,
Rent in 10th year = ![1800(1.115)^{10}](https://tex.z-dn.net/?f=1800%281.115%29%5E%7B10%7D)
= $5345.90
The value of this equation is 20.
