E^2x - e^x -56 =0
(E^x - 8) (e^x + 7) = 0
E^x - 8 = 0
E^x +7 = 0
X = ln8 or x = 2.07944154...
Answer:
m∠BXC = 70°.
We start out with m∠XBC. It is 55°, because it is a corresponding angle with ∠AXY.
Since ∠XBC and ∠XCB are the base angles of an isosceles triangle, they are congruent. This means that m∠XCB = 55°.
To find the measure of ∠BXC, we find the sum of the two base angles in the isosceles triangle and subtract it from 180:
180-(55+55) = 180-110 = 70°

Answer:
<h2>h = 18 in.
</h2><h2 />
Step-by-step explanation:
Area of a rectangular canvas = base x height (A = b*h)
where A = 252 in²
b = 14 in
find: height (h)
solution:
just plugin the values into the formula:
252 = 14 * h
h = 252 / 14
h = 18 in
Answer:
See below
Step-by-step explanation:
To solve a proportion ( an equation with two equal fractions), cross multiply by multiplying numerator and denominator of each fraction.
8/5=24/h 8h = 5*24 8h = 120 h=15
h/8=24/5 5h = 8*24 5h = 120 h= 24
h/5=24/8 8h =5*24 8h = 120 h=15
8/5=h/24 5h = 8*24 5h = 120 h=24
8/24=5/h 8h = 24*5 8h = 120 h = 15
5/8=h/24 8h = 5*24 8h =120 h = 15
h/5=8/24 24h =5*8 24h = 40 h = 5/3
To answer this question, we would use the combination formula which is
nCr, where n is the the number of objects and r is the sample.
So n would be 10, and r would be 4, since that is what we need to group.
<span>10 choose 4 is written 10C4, or C(10,4), and equals 10!/(4!(10-4)!)=10!/(4!6!)=10*9*8*7/(1*2*3*4) = 210</span>
