I need help because I'm solving these questions by the manual, and yet it still says that I am wrong after multiple attempts.

Mathematics
1 answer:
Alexxandr [17]3 years ago
6 0

Answer:

1. QR = HI

2. angle W and angle T

3. WB = UV

Step-by-step explanation:

It could me fill in the part of the proof, since I notice on all of them they only mark one or two of the congruencies on the shapes. I'm not really sure of 3's answer.

Hope this helped somewhat and good luck

10. The coordinates of C and D are 4 and -28 respectively, and F mdpt CD. Solve for:
Zigmanuir [339]

Answer:

a) mCD=7

b) mCF=7

c) mFD=7

d) F(2,-14)

Step-by-step explanation:

Let  the coordinates of C and D be (4,0) and (0,-28) respectively  and F is the midpoint of CD

a) mCD  

Slope formula  

m= \frac{y_2-y_1}{x_2-x_1}

m= \frac{-28-0}{0-4}

m= \frac{-28}{-4}

m= 7

mCD=7

b) mCF  

mCF=mCD

Hence mCF=7

c) mFD

mFD=mCD

Hence mFD=7

d) Coordinates of F :  mid point formula

Mid points Formula

x= \frac{x_2+x_1}{2}

x= \frac{0+4}{2}=\frac{0+4}{2}=2

y= \frac{y_2+y_1}{2}=\frac{-28+0}{2}=\frac{-28}{2}=-14

coordinates of F are (2,-14)

Mountains poem in nepali for class 7​
dalvyx [7]

Step-by-step explanation:

म नजन्मिदै विधवा भएकी हिमाल

खै! किन हो मेरा यी हेर्ने नयनले उनलाइ

अझै पनि दिन र रातमा

सेतै लुगा पहिरिएकी देख्छ

अचम्म लाग्छ मलाइ पहिरिएकी सेतो लुगा माथि

मुनालले पाइला टेके पनि विष्ठा गरे पनि कहिल्यै

मैलो हुदैन सेतो लुगाको वास्तविक रङ

उत्तिकै सेतो देख्छु म

निर्जीव वस्तु भएनी हिमाललाइ

सजीव मनुस्यको जस्तै चोटको कल्पना गरेको छु मैले

किनकी चोटै चोटले ग्रसित भएकी उनी आजभोली

अपाङ्गको सिकार बनिसकेकी छिन

उनलाइ अन्धो भन्छु म किनकी उनी आँखा देख्दैनन

आँखा नदेखे पनि अरु कसैलाइ सुम्सुम्याउन समेत सक्दैनन

तर पनि कस्तुरी, डाफे,मुनाल,घोरल,चितुवा आदि जनावरहरुको

सहारा दिने आश्रय स्थल भएर उभिएकी छिन, के कम छिन र?

जमिन भित्र उनको खुट्टा गाडिएर होला

खुट्टाको दृश्य मैले अझै पनि देख्न पाएको छैन

कस्तो होला है! हिमालको खुट्टा ? सोचिरहन्छु म

सायद खुट्टा नै छैन र पो कहिल्यै पनि हिड्डुल गर्न सक्दैनन कि?

जब कुनै समयमा चुचुरोमा हावा बहन थाल्यो

एकदिन सेतो कपाल धरतीमा हाम फालेर

नदिहरु बढ्न थाले तर उहीँ बहेको हावाले

हिमालको श्रवण गर्ने कानको जाली

नै फुटाइदिएछ त्यही भएर म भन्छु

हिमाललाइ बहिरो पनि हुनुहुन्छ तपाईं

सधै टोलाएर बसेकी देख्छु म

रोजगारी भन्ने कुरा त उहीँ हो हिमाललाइ

बिहानीपख देखि सन्ध्या काल सम्म

प्रकृतिले बसिबसी ऐना टल्काउने

पदभार ग्रहण गराइदिएको छ जब घाम

झुल्किन्छ उनी अस्ताउन्जेल सम्म ऐना टल्काइरहन्छिन्

त्यसैले म भन्छु हिमाललाइ बिधवा भएर के भो त

खान लाउनको लागि रोजगारी मिलेकै छ क्यारे !

Identify the vertex, roots, and equation of the function below.
spayn [35]

The equation of a parabola in vertex form, is:

y=a(x-h)^2+k

Where <em>(h,k)</em> are the coordinates of the vertex.

From the given graph, notice that the coordinates of the vertex are:

(5,6)

The roots are the values of <em>x</em> where the graph crosses the x-axis. In this case, the graph crosses the x-axis at the points <em>(4,0)</em> and <em>(6,0).</em> Then, the roots are:

\begin{gathered} x_1=4 \\ x_2=6_{}_{} \end{gathered}

Substitute the values of the vertex into the equation of the parabola in vertex form:

y=a(x-5)^2+6

To find the value of <em>a</em>, substitute <em>(x,y)=(4,0)</em>:

\begin{gathered} 0=a(4-5)^2+6 \\ \Rightarrow0=a(-1)^2+6 \\ \Rightarrow0=a+6 \\ \Rightarrow-6=a \\ \Rightarrow a=-6 \end{gathered}

Therefore, the equation of the parabola is:

y=-6(x-5)^2+6
