Answer:

$(61x + 3) = 125 \degree$

$(25x + 5) =55 \degree$

Step-by-step explanation:

The first angle us (61x+3)

The second angle is (25x+5)

We use corresponding angles to get the top angle as a linear pair to (25x+5).

We use sum of angles on a straight line to obtain:

$(61x + 3) + (25x + 5) =180 \degree$

Group similar terms

$61x + 25x = 180 - 3 - 5$

$86x = 172$

$x = 2$

We substitute to get:

$(61x + 3) = 61 \times 2 + 3 = 125 \degree$

$(25x + 5) =25 \times 2 + 5 = 55 \degree$

A principal of $3500 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 13 years? Us

Anna71 [15]

The equation is for when you compound annually is
$A=P(1+r)^t$

A=future amount
P=initial amount or principal
r=interest rate in decimal form
t=time in years

so
A=A
P=3500
r=7.5%=0.075
t=13

$A=3500(1+0.075)^{13}$
$A=3500(1.075)^{13}$
use your calculator
A=8961.4457
round to nearest dollar
A=$8961

that's how much the investment will be worth after 13 years

Verify the identity (tan x + 1)^2 + (tan x-1)^2= 2 sec^2 x

Elina [12.6K]

$(\tan x+1)^2+(\tan x-1)^2=2\sec^2x\\\\\text{use}\ \tan x=\dfrac{\sin x}{\cos x}\\\\L_s=\left(\dfrac{\sin x}{\cos x}+\dfrac{\cos x}{\cos x}\right)^2+\left(\dfrac{\sin x}{\cos x}-\dfrac{\cos x}{\cos x}\right)^2\\\\=\left(\dfrac{\sin x+\cos x}{\cos x}\right)^2+\left(\dfrac{\sin x-\cos x}{\cos x}\right)^2\\\\=\dfrac{(\sin x+\cos x)^2}{\cos^2x}+\dfrac{(\sin x-\cos x)^2}{\cos^2x}\\\\\text{use}\ (a\pm b)^2=a^2\pm2ab+b^2$

$=\dfrac{\sin^2x+2\sin x\cos x+\cos^2}{\cos^2x}+\dfrac{\sin^2x-2\sin x\cos x+\cos^2}{\cos^2x}\\\\=\dfrac{\sin^2x+2\sin x\cos x+\cos^2+\sin^2x-2\sin x\cos x+\cos^2}{\cos^2x}\\\\=\dfrac{2\sin^2x+2\cos^2x}{\cos^2x}=\dfrac{2(\sin^2x+\cos^2x)}{\cos^2x}\\\\\text{use}\ \sin^2x+\cos^2x=1\\\\=\dfrac{2(1)}{\cos^2x}=2\cdot\dfrac{1}{\cos^2x}=2\left(\dfrac{1}{\cos x}\right)^2\\\\\text{use}\ \sec x=\dfrac{1}{\cos x}\\\\=2(\sec^2x)=2\sec^2x=R_s\\\\L_s=R_s\Rightarrow The\ identity$

A pair of vertical angles have the measure of 2y + 5 degrees + 4y degrees what is the value of y

timama [110]

Answer:

The value of y s 2.5

Step-by-step explanation:

Vertical angles are always equal to one another. In this case, we can find the angles by setting the two values equal and solving algebraically.

2y + 5 = 4y

5 = 2y

2.5 = y
