Svetlanka [38]

Answer:

Therefore, the two options for triangles to be congruent using AAS are

1. BC ≅ MQ       (Additional information)

2. AC ≅ RQ       (Additional information)

Step-by-step explanation:

Given:

∠CAB =∠MRQ = 29°

∠ABC = ∠RMQ = 116°

To Prove:

Δ ABC ≅ ΔRMQ  by AAS congruence test which additional information is required

Proof:

<u>Case 1.</u>

In  Δ ABC and Δ RMQ

∠CAB =∠MRQ = 29°      ……….{Given}

∠ABC = ∠RMQ = 116°     ..……..{Given}

BC ≅ MQ                        ……….{Additional information required}

Δ ABC ≅ Δ RMQ ….{By Angle-Angle-Side congruence test}

<u>Case 2.</u>

In  Δ ABC and Δ RMQ

∠CAB =∠MRQ = 29°      ……….{Given}

∠ABC = ∠RMQ = 116°     ..……..{Given}

AC ≅ RQ                        ……….{Additional information required}

Δ ABC ≅ Δ RMQ ….{By Angle-Angle-Side congruence test}

Therefore, the two options for triangles to be congruent using AAS are

1. BC ≅ MQ       (Additional information)

2. AC ≅ RQ       (Additional information)

It was recently estimated that homes without children outnumber homes with children by seven to five. If there are 3564 homes in
Gwar [14]

Answer:

2079

Step-by-step explanation:

Homes without children outnumbers homes with children by about 7 to 5 ;

If number of children = 3564

Number of homes without children :

Expressing the relaship interms of ratio :

Without children : with children = 7 :5

Total ratio = 7 + 5 = 12

Number of homes without children:

(7 / 12) * 3564

0.5833333 * 3564

= 2079

What's the larger angle?
topjm [15]

Answer:

100°

Step-by-step explanation:

Since the angles om a straight line add up to 180°

10x°+8x°=180°

18x°=180°

x=10

The larger angle = 10x°

= 10(10)°

= 100°

determine whether AB and CD are parallel, perpendicular,or neither. A(-1,-4), B(2,11), C(1,1), D(4,10)
sergiy2304 [10]

Step-by-step explanation:

the x distance from A to B is 3 (from -1 to 2), and the y distance is 15 (from -4 to 11).

the x distance from C to D is also 3 (from 1 to 4), but the y distance is 9 (from 1 to 10).

so, the slopes are different

AB : 15/3 = 5

CD : 9/3 = 3

and the lines are therefore not parallel.

perpendicular slopes are simply inverting y and x in the ratio and flip the sign (from - to + and vice versa). but that is not the case here either (just to start - both slopes are positive).

so, the 2 lines are "neither".

Hey, I need help with questions 1 and 2, if anyone can help, please? thanks!
Eva8 [605]

The correct works are:

  • Blue(s + h) = 2s^2 + 4sh + 2h^2 + 3.
  • \frac{Blue(s + h) - Blue(s)}{h} = 4s + 2h

<h3>Function Notation</h3>

The function is given as:

Blue(s) = 2s^2 + 3

The interpretation when Steven is asked to calculate Blue(s + h) is that:

Steven is asked to find the output of the function Blue, when the input is s + h

So, we have:

Blue(s + h) = 2(s + h)^2 + 3

Evaluate the exponent

Blue(s + h) = 2(s^2 + 2sh + h^2) + 3

Expand the bracket

Blue(s + h) = 2s^2 + 4sh + 2h^2 + 3

So, the correct work is:

Blue(s + h) = 2s^2 + 4sh + 2h^2 + 3

<h3>Simplifying Difference Quotient</h3>

In (a), we have:

Blue(s + h) = 2s^2 + 4sh + 2h^2 + 3

Blue(s) = 2s^2 + 3

The difference quotient is represented as:

\frac{f(x + h) - f(x)}{h}

So, we have:

\frac{Blue(s + h) - Blue(s)}{h} = \frac{2s^2 + 4sh + 2h^2 + 3 - 2s^2 - 3}{h}

Evaluate the like terms

\frac{Blue(s + h) - Blue(s)}{h} = \frac{4sh + 2h^2}{h}

Evaluate the quotient

\frac{Blue(s + h) - Blue(s)}{h} = 4s + 2h

Hence, the correct work is:

\frac{Blue(s + h) - Blue(s)}{h} = 4s + 2h
