Answer:

False

Step-by-step explanation:

Since, we are given that the STL is a plane and also Z is a plane, then according to geometry, their intersection will give a line. Since, VTX is also a plane according to the figure given, therefore, intersection of the two planes that is STL and Z will give a line and not the plane VTX. Therefore, plane STL and plane Z will not intersect at VTX.

Hence, the given statement is false.

Two ships depart from a port at the same time, one heading south and the other east. Seven hours later, they are separated by a

Anuta_ua [19.1K]

Answer: 80 miles for the first ship, and 150 miles for the other.

Explanation:

First thing we should do is correspond each number with a letter:

Let x be the distance travel by ship heading east

Let y be the distance travel by ship heading south

y = x + 70 -- (1)

sqrt(x^2 + y^2) = 170 -- (2)

Subtract (1) into (2):

sqrt(x^2 + (x + 70)^2) = 170

x^2 + x^2 + 140x + 4900 = 28900

2x^2 + 140x - 24000 = 0

x ^2 + 70x - 12000 = 0

(x - 80)(x + 150) = 0

x = 80 or -150

Since the distance for the first ship can’t be negative, therefore, x = 80 -- (3)

Subtract (3) into (1), therefore, y = 150

Hope this helps! :)

Look at the way that Samuel answered the question above.

Solnce55 [7]

A) Multiplication is done wrong. The + sign with 16 underlined in the term -16m+16=-16 is wrong. it should be -16.

B) After solving $-2(8m+8)=-16$ correctly we get m=0

Step-by-step explanation:

A) Explain his mistake in complete sentences.

Samuel has done the mistake while performing the step:

$-2(8m+8)=-16$

When we multiply -2 with the terms inside the bracket, we apply the rule that if we have one positive sign (+) and one negative sign (-) while multiplying the result would have negative sign(-) i.e,

$-16m-16=-16$

While Samuel has calculated as $-16m+16=-16$

The + sign with 16 underlined in the term -16m+16=-16 is wrong. it should be -16.

B) Explain how to solve the equation correctly

Now, solving the given expression:

$-2(8m+8)=-16\\Multiplying\,\,-2\,\,with\,\,terms\,\,inside\,\,the\,\,bracket.\\-16m-16=-16\\Adding\,\,+16\,\, on\,\, both\,\, sides\\-16m-16+16=-16+16\\-16m=0\\Divide\,\,both\,\,sides\,\,by\,\,-16\\m=0$

So, the value of m is m=0
