Answer:
<h2>25</h2>
Step-by-step explanation:
The rate of change of number of tree y on x branches of a tree is expressed as shown;
m = Δy/Δx where;
m is the rate of change
Δy is the change in number of leaves between 3 and 4
Δx is change in number of branches between 3 and 4
m = Δy/Δx = y₂-y₁/x₂-x₁
From table between 3 and 4, y₂ = 100, y₁ = 75, x₂ = 4, x₁ = 3
m = 100-75/4-3
m = 25/1
m = 25
<em>Hence the rate of change between 3 and 4 branches is 25</em>
Answer:
y<-6 and y>10
Step-by-step explanation:
In 2005, 23 is in the second deviation
19 22 25 28 31 33 35
In 1965, 23 is in the third deviation.
12 14 16 18 20 22 24
<span>By the way, 13.5% range from 22 to 25 in 2005, while 2.1% range from 22 to 24 in 1965</span>
M<A = <span>20°
m<B = m<C = 8</span><span>0°
</span>Law of Sines , in any triangle we have
a/sin A = b/sin B = c/sin c<span>
4/sin20 = AC/sin80 = AB/sin80
now we can solve AC
</span>4/sin20 = AC/sin80
<span>AC = 4 (sin80)/ sin20
AC = 4(0.98) / (0.34)
AC = 3.92 / 0.34
AC = 11.52
answer
</span>C.11.52 centimeters<span>

Answer:
x=5
Step-by-step explanation:
According to SSS, RPS and RPQ should be similar angles. Since the length RP is the same, then RQP and RSP should be similar too. Therefore PRS and PRQ should be similar too. Since QP and RS are the same (7) then QR and PS needs to be same in length too.
2x+3 = 4x-7
10 = 2x
x=5
