The first one shown, 400/2, is showing the point on the graph where she walks 400 ft in 2 minutes. In order to find the next proportion, you just have to look two minutes over which in this case is 800 ft for 4 minutes... written 800 over 4.

Construct a triangle ABC where BC =4cm ,B=60° and AB+AC=6cm

Fittoniya [83]

Answer:

Below is the step-by-step explanation.

Step-by-step explanation:

To determine:

Construct a triangle ABC

Information Fetching and Information Steps:

From the given data,

$BC\:=\:4\:cm$

$B=60^{\circ }$

$AB+AC=6\:cm$

Procedure:

First draw a line segment $BC\:=\:4\:cm$

Then construct angle of $m$ ∠ $60^{0}$ at $B$ on $BC$ .

Taking $B$ as center with $6\:cm$ radius, draw an arc which cuts the ray of $m$ ∠ $60^{0}$ at $X$ .

Then Join $X$ and $C$ .

The draw a perpendicular bisector of $XC$ .

Wherever this perpendicular bisector intersect $BX$ , name that point as $A$

Join $A$ and $C$ .

Thus, ∆ $ABC$ will be a required triangle.

Keywords: triangle, perpendicular bisector, angle

Answer:D

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 8.5%/100 = 0.085 per year

putting time into years for simplicity

6 months ÷ 12 months/year = 0.5 years

then, solving our equation

I = 10000 × 0.085 × 0.5 = 425

I = $ 425.00

on a principal of $ 10,000.00

at a rate of 8.5% per year

for 0.5 years (6 months) is $ 425.00

A) Find a particular solution to y" + 2y = e^3 + x^3. b) Find the general solution.

Reptile [31]

Answer:

a.P.I= $\frac{e^{3x}}{11}+\frac{1}{2}(x^3-3x)$

b.G.S= $C_1Cos \sqrt2 x+C_2 Sin\sqrt2 x+\frac{1}{11}e^{3x}+\frac{1}{2}(x^3-3x}$

Step-by-step explanation:

We are given that a linear differential equation

$y''+2y=e^{3x}+x^3$

We have to find the particular solution

P.I= $\frac{e^{3x}}{D^2+2}+\frac{x^3}{D^2+2}$

P.I= $\frac{e^{3x}}{3^2+2}+\frac{1}{2} x^3(1+\frac{D^2}{2})^{-2}$

P.I= $\frac{e^{3x}}{11}+\frac{1-2\frac{D^2}{4}+3\frac{D^4}{16}+...}{2}x^3$

P.I= $\frac{e^{3x}}{11}+\frac{x^3-2\frac{\cdot3\cdot 2x}{4}}{2}+0}$ (higher order terms can be neglected

P.I= $\frac{e^{3x}}{11}+\frac{1}{2}(x^3-3x)$

b.Characteristics equation

$D^2+2=0$

$D=\pm\sqrt2 i$

C.F= $C_1cos \sqrt2x+C_2 sin\sqrt2 x$

G.S=C.F+P.I

G.S= $C_1Cos \sqrt2 x+C_2 Sin\sqrt2 x+\frac{1}{11}e^{3x}+\frac{1}{2}(x^3-3x)$

A 3 foot wide painting should be centered on 13 foot wide wall how many feet should be on each side of the painting

VLD [36.1K]

Answer:

5 feet of wall should be on each side of the painting.

Step-by-step explanation:

Given that a 3 foot wide painting should be centered on 13 foot wide wall, to determine how many feet should be on each side of the painting, the following calculations must be performed:

(13 - 3) / 2 = X

10/2 = X

5 = X

Therefore, 5 feet of wall should be on each side of the painting.
