Answer:

The root of this equation would be A) x=1

Step-by-step explanation:

To get this, you first need to bring the 98x over to the left side.

49x^2-98x+49=0

Then, you can simplify the equation by taking out 49.

49(x^2-2x+1)=0

Then, factor that equation to get 49(x-1)(x-1)=0 or 49(x-1)^2=0

Thus, your root would be x=1

Sorry this is a little late, but I hope this helped you!

Afina-wow [57]

Answer:

A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.

Anuta_ua [19.1K]
Hello,
let
t=(-4)+(-12)+(-20)+(-28)+(-36)+....=-(4+12+20+28+36+...)=-s

a_{1}=4=-4+1*8
a_{2}=12=-4+2*8
a_{3}=20=-4+3*8
a_{4}=28=-4+4*8

...
a_{18}=?=-4+18*8=140

a_{i}=-4+i*8

s=\sum_{i=1}^{18} (-4+i*8)=\sum_{i=1}^{18} (-4)+\ 8*\sum_{i=1}^{18}(i)\\\\=(-4)*18+8*(1+2+3+4...+18)\\\\=-72+\frac{(1+18)*18}{2}\\\\=-72+171=99

\boxed{\ t=-99}

The sides of an isosceles triangle have lengths of 10, 10, and 4. Find the measures of the base angles.
kotegsom [21]

Answer:

The base angles measure 78.46 degrees to the nearest hundredth.

Step-by-step explanation:

Applying the Cosine Rule:

10^2 = 10^2 + 4^2 - 2.4.10cosX     where X is a base angle.

cos X = (100 - 100 - 16)/ (-80)

cos X = -16/-80

cos X = 0.2

X = 78.463 degrees
