Answer 1

Answer:

  B

Step-by-step explanation:

The dimensions of A and B are, respectively, (3, 2) and (2, 2). This means the dimensions of the product will be (3, 2), the same as A. This eliminates answer choices A and C immediately.

__

To determine whether the answer is B or D, find a term in which those matrices differ. Then compute that term from A and B.

Here, term (1, 2) is -37 in choice B and -32 in choice D. The actual product term is the dot product of row 1 of A and column 2 of B:

  [1, -4]·[7, 11] = (1)(7) +(-4)(11) = 7 -44 = -37 . . . . matches choice B

__

Your scientific or graphing calculator can probably compute the matrix product for you. Certainly, any spreadsheet can, as shown in the attachment.

A child casts a shadow 1.3 m long. The distance from the top of the child’s head to the end of the shadow is 1.9 m. To the nearest centimetre, how tall is the child?

Answers

Answer:

Height of the boy is 1.4 m and casts a shadow of 1.2 m

At the same time, a building casts a shadow of 5.4 m and suppose height of the building is x m

Then ratio of their heights and shadows are in proportion

⟹1.4x=1.25.4

⟹x=1.21.4×5.4

⟹x=6.3

Hence, height of the building is 6.3 m.

Ann's parents are not Christians. They forbid Ann to visit her Christian friends.


Do you think Ann should obey her parents? Why or why not?

Answers

Answer:

No

Step-by-step explanation:

It is very healthy for someone to be with a community of likeminded individuals although the bible indeed supports obedience to one's parents, that's only in affect unless what they are telling you to commit sinful acts. In this case Ann's parents are forbidding her to see her Chirstian friends which is sinful speaking how Christians are considered God's people. Even though God expects you to honor your parents, you cannot honor the dishonorable.

Leviticus 19:3 "Every one of you shall revere his mother and his father, and you shall keep My Sabbaths; I am the LORD your God."
Colossians 3:21 "Fathers, do not provoke your children, lest they become discouraged."
Romans 12:18 "If possible, so far as it depends on you, live peaceably with all."

God is speaking during times when his people were raised by good parents who have the fear of the Lord in their hearts. In these times they're many "bad" parents who don't honor the Lord's teachings which they themselves should not be honored.

Hope this helps.

Find the distance between two points: (5,3),(8,5)​

Answers

Answer:

[tex] \displaystyle\boxed{\rm \: Distance= \underline{\underline{\sqrt{13}}}} [/tex]

OR in Decimal,

[tex] \boxed{\rm \: Distance=\underline{\underline{3.605}}}[/tex]

Step-by-step explanation:

Given:

Two points, that is (5,3) & (8,5)

To Find:

The Distance of the two given points

Solution:

To Find the distance between two points, we will use the distance formula, i.e. :

[tex] \boxed{ \rm \: Distance = \sqrt{(x_2 - x_1) {}^{2} + (y_2 - y_1) {}^{2} } }[/tex]

According to the Question,

[tex] \rightarrow \: \rm \: x_2 = 8[/tex]

[tex]\rightarrow \: \rm \: x_1 = 5[/tex]

[tex]\rightarrow \: \rm \: y_2 = 5[/tex]

[tex]\rightarrow \: \rm \: y_1 = 3[/tex]

Now Substitute the values on the formula of Distance and then Simplify:

[tex] \rm \: Distance= \sqrt{(8 - 5 )^{2} + (5 - 3) {}^{2} } [/tex]

[Follow PEMDAS rule while simplifying]

[tex] \rm \: Distance= \sqrt{3 {}^{2} + 2 {}^{2} } [/tex]

[tex] \rm \: Distance= \sqrt{(3 \times 3) + (2 \times 2)} [/tex]

[tex] \rm \: Distance= \sqrt{9 + 4} [/tex]

[tex] \rm \: Distance= \sqrt{13} [/tex]

[tex] \rm \: Distance= {3.605} [/tex]

Hence, the distance between the two given points would be [tex]\sqrt{13}[/tex] or [tex] 3.605 [/tex].

Answers

Answer:

Step-by-step explanation:

[tex]\sqrt{82}=9.06[/tex]

10² ÷ 5 *√82 - π*2 = 100÷ 5 *9.06 - 3.14*2

                              = 20 *9.06 - 3.14*2

                              = 181.2 - 6.28

                              = 174.92

or

10² ÷5 *√82 - π*2 = 100÷5 *√82 - 2π

                             = 20√82-2π

Answer:

[tex]10^2 \div 5 \times \sqrt{82} - \pi \times 2[/tex]

Using order of operations, we need to carry out the exponents first:

[tex]10^2=10 \times 10=100[/tex]

[tex]\implies 100 \div 5 \times \sqrt{82} - \pi \times 2[/tex]

Then we need to carry out multiplication and division (it doesn't matter in which order):

[tex]\implies 100 \div 5 \times \sqrt{82} - \pi \times 2[/tex]

[tex]\implies 20\times \sqrt{82} - 2\pi[/tex]

[tex]\implies 20\sqrt{82} - 2\pi[/tex]

Unless you have been given an approximation for pi, it cannot be simplified any further.

The job pays $250 for ten hours of work.
He needs to make $750.
How many hours of tutoring would Mr. White need to work?

Answers

Answer:

30 hours of work

Step-by-step explanation:

Ok if Mr. White  works 10 hours he gets 250$
250+250=500$
10 + 10 = 20 hours
500+250=750
20+ 10 = 30

so this means he will have to work 30 to get 750$

Answer:

30 hours

Step-by-step explanation:

If 10 hours = $250

Than you can divide 750/250 and you’ll get 3. Multiply 3 by 10 ( 3 • 10 ) and you’ll get 30 hours.
