Answer:

b1 = A/h - b2

Step-by-step explanation:

<u>Given equation:</u>

A = (b1 + b2)h

<u>Solving for b1:</u>

A = (b1 + b2)h ⇒ divide both sides by h
A/h = b1 + b2 ⇒ subtract b2 from both sides
b1 = A/h - b2 ⇒ answer

The directex of Y=1/8x^2 is?

nexus9112 [7]

$\bf \textit{parabola vertex form with focus point distance}\\\\
\begin{array}{llll}
(y-{{ k}})^2=4{{ p}}(x-{{ h}}) \\\\
\boxed{(x-{{ h}})^2=4{{ p}}(y-{{ k}})} \\
\end{array}
\qquad 
\begin{array}{llll}
vertex\ ({{ h}},{{ k}})\\\\
{{ p}}=\textit{distance from vertex to }\\
\qquad \textit{ focus or directrix}
\end{array}\\\\
-------------------------------\\\\
y=\cfrac{1}{8}x^2\implies (y-0)=\cfrac{1}{8}(x-0)^2\implies 8(y-0)=(x-0)^2
\\\\\\
4(2)(y-0)=(x-0)^2\impliedby \textit{that means, p = 2}$

so... if you notice, the vertex is at h,k and that'd be the origin, 0,0

so...since the directrix is "p" units from the vertex, so it'd be 2 units from 0,0

now, the parabola has an equation with a positive leading term's coefficient, namely the 1/8 is positive, thus, the parabola is opening upwards, and the directrix is "outside" the parabola, so is below the vertex

that puts the directrix 2 units below 0,0

y = -2

Rama is stringing beads whose lengths are each 0.19 inches. How can rounding be used to estimate the length of a row of 9 beads?

Mice21 [21]

Since the beads are about 0.20 inches, the length of a row of 9 beads will be approximately 9 × 0.20 = 1.80 inches.

Step-by-step explanation:

According to given statement;

Length of individual stringing beads = 0.19 inches

Rounding off = 0.2 inches

Length of row of 9 beads = 9* rounded off length of individual beads

Length of row of 9 beads = 9*0.2

Length of row of 9 beads = 1.80 inches

Since the beads are about 0.20 inches, the length of a row of 9 beads will be approximately 9 × 0.20 = 1.80 inches.
