Độ dài cạnh = 2/4 đáy là : 20 . 2/4 = 10cm

Độ dài cạnh = 1/2 tổng chiều cao và đáy là : 1/2( 15 + 20 ) = 17, 5cm

Chu vi hình tam giác = 10 + 17, 5 + 20 = 47, 5cm

Diện tích hình tam giác = 1/2(20.15) = 150cm2

6 tháng 8 2020

Diện tích tam giác là:20x15:2=150(cm2)

Độ dài cạnh thứ nhất là:20x2/4=10(cm)

Độ dài cạnh thứ hai là:(20+15)x1/2=17,5(cm)hoặc bằng 35/2cm

Chu vi tam giác là:20+10+17,5=47,5(cm)

                  Đ/S:Diện tích:150cm2

                         Chu vi:47,5cm

Áp dụng t/c dãy tỉ số bằng nhau ta có : 

\(\frac{x}{5}=\frac{y}{6}=\frac{z}{7}=\frac{x-y}{5-6}=\frac{36}{-1}=-36\)

Làm nốt nhé !

Ta có : x - y = 36

Lại có:\(\frac{x}{5}=\frac{y}{6}=\frac{z}{7}=\frac{x-y}{5-6}=\frac{36}{-1}=-36\)(dãy tỉ số bằng nhau)

=> \(\hept{\begin{cases}x=-180\\y=-216\\z=-252\end{cases}}\)

a) Áp dụng tính chất tia phân giác 

=> \(\frac{DB}{DC}=\frac{AB}{AC}=\frac{3}{4}\)

Áp dụng định lí Pytago => \(BC=10\)=> \(DB+DC=10\)

=> \(DB=\frac{30}{7};BC=10\)

b) Đây là 1 HTL (Đi thi ko cần phải chứng minh) (\(AH^2=HB.HC\))

c) Tam giác EBD đồng dạng tam giác ABC (gg) khi có chung góc B và BED=BAC=90 (gt)

=> \(\frac{EB}{BD}=\frac{AB}{BC}\)

=> \(EB.BC=BD.AB\)(ĐPCM)

d) Áp dụng HTL: \(\frac{1}{AH^2}=\frac{1}{AB^2}+\frac{1}{AC^2}\)

Thay AB=6; AC=8 vào: 

=> \(\frac{1}{AH^2}=\frac{25}{576}\)

=> \(AH=\frac{24}{5}\)

Ta tiếp tục áp dụng HTL: \(BH.BC=AB^2\)

Thay AB=6; BC=10 (CMT) vào ta được:

=> \(BH=\frac{36}{10}\)

Có: \(BD=\frac{30}{7}\)(CMT) => \(HD=\frac{24}{35}\)

=> Diện tích tam giác AHD = \(\frac{AH.HD}{2}=\frac{24}{35}.\frac{5}{24}:2=\frac{1}{14}\)

Vậy diện tích tam giác AHD = \(\frac{1}{14}\)(cm^2)

\(\left(\frac{1}{3}+\frac{1}{6}\right).2^{x+4}-2^x=2^{13}-2^{10}\)

\(\frac{1}{2}.2^x.2^4-2^x=8192-1024\)

\(2^x.8-2^x=7168\)

\(2^x\left(8-1\right)=7168\)

\(2^x.7=7168\)

\(2^x=7168\div7\)

\(2^x=1024\)

\(2^x=2^{10}\)

\(\Rightarrow x=10\)

Vậy \(x=10\).

(1/3+1/6).2^x.2^4-2^x=8192-1024

(1/3+1/6).2^x.2^4-2^x=7168

1/2.2^x.2^4-2^x=7168

1/2.2^x.(2^4-1)=7168

1/2.2^x.(8-1)=7168

1/2.2^x.7=7168

1/2.2^x=7168:7

1/2.2^x=1024

      2^x=1024:1/2

     2^x=2048

2^x=2^11

x=11

vậy x=11

câu 14 nào ?

Ta có: \(35^2\equiv375\)( mod 425) 

\(35^3=35.35^2\equiv35.375\equiv375\)( mod 425)

\(35^4=35.35^3\equiv35.375\equiv375\)( mod 425) 

\(35^8=35^4.35^4\equiv375.375\equiv375\)( mod 425) 

\(35^{16}\equiv35^8.35^8\equiv375.375\equiv375\)( mod 425) 

\(35^{32}\equiv35^{16}.35^{16}\equiv375.375\equiv375\)( mod 425) 

=> \(35^2-35^3+35^4-35^8+35^{16}+35^{32}\equiv375-375+375-375+375+375\equiv325\)( mod 425) 

Vậy số dư cần tìm là 325
