Answer:

Yes

Step-by-step explanation:

Pythagorean theorem states that for right triangles a^2 + b^2 = c^2, which is true for this as a^2 = 1225 + 144 (b^2) = 1369,

1369 = 37^2

Graph the set of points. Which model is most appropriate for the set?

Tamiku [17]

Check the slope between the moving points

<span>slope between (–6, –1) & (–3, 2) = 1 </span>
<span>slope between (-3, 2) & (–1, 4) = 1 </span>
<span>slope between (-1, 4) & (2, 7) = 1 </span>

<span>the points are collinear and make an angle of 45 degrees with the x-axis </span>

<span>we can have an equation of a line passing through (-6,-1) and slope 1 as </span>

<span>(y + 1) = 1(x + 6) </span>
<span>y = x + 5 is your linear model mostly</span>

Solve the equation for x.<br> -=7<br> Answer here

Leviafan [203]

Complete Question:

Solve the equation for x

$x-7=7$

Answer:

$x = 14$

Step-by-step explanation:

Given

$x-7=7$

Required

Solve for x

$x-7=7$

Add 7 to both sides

$x-7+7=7+7$

$x=7+7$

$x = 14$

Hence:

For $x-7=7$ , $x = 14$

Rich also has £400 pounds invest 3% compound interest . How many years does he need to invest the money to get at least £475

zepelin [54]

Answer: 6 years

Step-by-step explanation:

Formula to calculate compound amount: $A=P(1+r)^t$ , where P= Principal , r=rate of interest, t= time

Given: P = £400, r = 3% = 0.03 , A= 475

Required equation: $400(1+0.03)^t\geq475$

$400(1.03)^t\geq475\\\\\Rightarrow\ (1.03)^t\geq\dfrac{475}{400}\\\\\Rightarrow\ (1.03)^t\geq1.1875$

Taking log on both sides , we get

$t \log 1.03\geq\log1.1875\\\\\Rightarrow\ t(0.0128372)\geq(0.0746336)\\\\\Rightarrow\ t\geq\dfrac{0.0746336}{0.0128372}=5.81385\approx6$

Hence, he needs to invest the money for 6 years to get atleast £475.
