Answer:

16ft rounded to nearest 10th You cna see which one from the two it was below,

The taller tree 14ft also had elevation 16ft to be closer and so the elevation of the taller tree just so happened to be nearer to the house.

This is because the 9ft tree elevation was further away and works out to be 18ft elevation so it cant be the shorter it has to be the bigger tree.

Answer is 16ft

Step-by-step explanation:

With the 9ft tall tree we count run 16 on x axis then count up and know its 9

We then work out the diagonal line through Pythagoras.

Where a sq + b sq = c sq

9sq + 16sq = ?

c sq = ? = ?

--------------

We try again with pen to work out

9sq + 16sq

csq = sqrt 81 + sqrt 256 = sqrt 337

csq = sqrt 337 = 18.35

Tree 9ft = 18.35 from house to top of the tree top

---------------

Tree 14ft tall

14sq + 8sq

csq = sqrt 196 + sqrt 64 = 260

csq = sqrt 260 = 16.12

Tree 14ft = 16.12 from house to top of tree top

Explain the process and the properties you have to use to solve the logarithmic equation: log(3)x + log(3)4 - 2 log(3)3 = 2

Akimi4 [234]

81/4

Step-by-step explanation:

$log_{3}( \frac{4x}{{3}^{2} } ) = 2$

${3}^{2} = \frac{4x}{ {3 }^{2} }$

9=4x/9

81=4×

x=81/4

adding logs means elements are multiplied, subtracting means divide. number in front of log is raised to power

base of log is raised to power of element after =

element in log is then equal to log base raised to power

solve resulting equation

Find equation of set of points pieces that its distance from the point 3, 4, -5 and -2, 1, 4 are equal.

Gnesinka [82]

Answer:

Step-by-step explanation:

Suppose we a point $P(x,y,z)$ such that its distance from either the point $A(3,4,-5)$ or $B(-2,1,4)$ is the same.

Using this information we can formula:

distance AP = distance BP

first, let's find the distance from AP, using the distance formula.

$r = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2 + (z_1 - z_2)^2}$

$AP = \sqrt{(3 - x_2)^2 + (4 - y_2)^2 + (-5 - z_2)^2}$

similarly, we can find the distance BP

$BP = \sqrt{(-2 - x_2)^2 + (1 - y_2)^2 + (4 - z_2)^2}$

since both distances are exactly the same we can equate them

$AP = BP$

$\sqrt{(3 - x_2)^2 + (4 - y_2)^2 + (-5 - z_2)^2} = \sqrt{(-2 - x_2)^2 + (1 - y_2)^2 + (4 - z_2)^2}$

we can simplify it a bit squaring both sides, and getting rid of the subscripts.

$(3 - x)^2 + (4 - y)^2 + (-5 - z)^2 = (-2 - x)^2 + (1 - y)^2 + (4 - z)^2$

what we have done here is formulated an equation which consists of any point P that will have the same distance from (3,4,-5) and (-2,1,4).

To put it more concretely,

This is the equation of the the plane from that consists of all points (P) from which the distance from both (3,4,-5) and (-2,1,4) are equal.

you are working on a project for school. the project will take 12 hours to finish in all. so far, you have worked on the project

nasty-shy [4]

Answer:

6 hours and 45 minutes

Step-by-step explanation:

First, convert 12 hours into minutes.

12*60=720

Convert 5 hours to minutes and add 15

5*60=300+15=315

Subtract 720 from 315.

720-315=405

Convert into hours and minutes.

405/60=6.75

0.75 of an hour is 45 minutes so the answer is 6 hours and 45 minutes.
