Answer:

One

Step-by-step explanation:

14/sin(54) = 7/sinC

sinC = 0.4045084972

C = 23.86, 156.14

Since 156.14+54 = 210.14 > 180

Only one triangle can be formed with angle 23.86° at C

Fundamental theorem of calculus <img src="https://tex.z-dn.net/?f=g%28s%29%3D%5Cint%5Climits%5Es_6%20%7B%28t-t%5E4%29%5E6%7D

Answer:

$\displaystyle g'(s) = (s-s^4)^6$

Step-by-step explanation:

The Fundamental Theorem of Calculus states that:
$\displaystyle \frac{d}{dx}\left[ \int_a^x f(t)\, dt \right] = f(x)$

Where a is some constant.

We can let:
$\displaystyle g(t) = (t-t^4)^6$

By substitution:

$\displaystyle g(s) = \int_6^s g(t)\, dt$

Taking the derivative of both sides results in:
$\displaystyle g'(s) = \frac{d}{ds}\left[ \int_6^s g(t)\, dt\right]$

Hence, by the Fundamental Theorem:

$\displaystyle \begin{aligned} g'(s) & = g(s) \\ \\ & = (s-s^4)^6\end{aligned}$

Solve each proportion. 2/4=4/p-3 pls help

eduard

Answer:

$p=\frac{8}{7}$

Step-by-step explanation:

$\frac{2}{4} = \frac{4}{p} - 3$

$\frac{1}{2} = \frac{4}{p} - 3$ (simplify)

$\frac{1}{2}+3 = \frac{4}{p} - 3+3$

$\frac{1}{2}+3 = \frac{4}{p}$ (Add 3 to both sides)

$\frac{7}{2}= \frac{4}{p}$ (simplify)

$\frac{7}{2}p= \frac{4}{p}*p$

$\frac{7p}{2}=4$ (Multiply both sides by p)

$\frac{7p}{2}*2=4*2$

$7p=8$ (Multiply both sides by 2)

$\frac{7p}{7}=\frac{8}{7}$

$p=\frac{8}{7}$ (Divide both sides by 7)

Use 1% or 10% to estimate 93% of 149 A. 169.5 B. 13.5 C. 112 D. 135

irakobra [83]

93% of 149

10% of 149 = 14,9

93% of 149 > 90% of 149

93% of 149 > 149 - 14,9 ≈ 149-15≈134
> 134
⇒ the answer is D
